Revision 10.01/9 corrects the following problems:
=============================================================================
CR 31179: IPX.
High CPU utilization during IPX updates may lead to out-of-buffer
faults.
CR 32284: OSPF.
A problem exits in router software versions 10.01 and later,
11.00 and later, and 11.01 and later, in which OSPF crashes if
you configure announce policies on the router to aggregate
external class C networks into class B or class A networks.
CR 31900: IP.
A problem exists in software version 11.01 using an ARE board in
which the router decrements the TTL by 2. This problem occurs only
when you enable an IP traffic filter on the ARE interface.
CR 32046: Source Route Bridge.
If you disable the Source Route Bridge (SRB) base when booting the
router, a bus error may occur.
CR 32155: Source Route Bridge.
If you enter an invalid Source Router Bridge (SRB) interface Ring
ID, an invalid SRB bridge ID, or an invalid SRB internal LAN ID
using the Technician Interface, an orphan buffer occurs.
CR 30411: DLSw.
Enhancement request to remove a single DLS connection from a DLS
router. Currently, if a single connection hangs, you must globally
disable and reenable DLS to clear the connection. This feature
should be provided via a MIB set, and does not need to be
available using Site Manager.
CR 31178: IPX.
The IPX ping request packet length is 37 bytes even though the
length field indicates a packet length of 36.
CR 31702: DLSw.
Terminating NetBIOS over DLSw on an ARE interface LEC causes a
Midpage Read Error to occur.
CR 28711: GAME.
CR 27869
The router restarts with a "System restart in tmo_wdog.c at line 70"
message after several CANUREACH messages.
CR 29066: DLSw.
If a station receives two RIFs at same time, the second RIF
will be cached instead of the first.
------------------------------------------------------------------------------
Revision 10.01/8 corrects the following problems:
=============================================================================
CR 30791: ATM.
Routers running router software 10.00 or later will fail to
acknowledge LE_ARP responses from the C100, causing intermittent
connectivity problems between the router and the switch.
CR 29796: SWSERV.
The second SPID registration fails after a line failure.
CR 31517: ATM LANE.
Routers running router software 10.00 or later will fault on the
ARE interface upon receipt of an IP multicast packet.
CR 19627: GAME.
If A BN router contains only an ARE (and its link module) without a
Flash card and no other boards in any other slot, the router will
not boot.
CR 31177: ATM.
Bridge frames are not being forwarded over ATM PVCs defined as
Hybrid Mode using 1490 encapsulation.
CR 29985: Telnet.
When using the console dial-up terminal window to telnet to a
another system and the telnet connection disconnects unexpectedly,
you are unable to reestablish the call.
CR 29113: GAME.
When a router configured for end station support receives an ARP
request for one of its interfaces with a RIF, the router responds
correctly to the ARP request and prints the same log message
repeatedly until it eventually experiences a bus error.
CR 17128: ISDN_DRVR.
The command "show isdn bri stats" is unable to retrieve B
channel statistics using ISDN scripts. Instead, it retrieves only
the D channel statistics.
CR 30445: DLSw.
After deleting llc2 from an Ethernet interface on which DLSw was
configured, the router experienced a bus error. Following the bus
error, devices on this interface fail to respond to a ping command.
CR 31259: Switched Services.
The second SPID registration fails after a line failure.
CR 27393: Learning Bridge.
If you have Learning Bridge (LB) running on a router with at least
1 learning bridge interface configured and you dynamically disable
LB then add another LB interface on another slot, the router
experiences a bus error.
CR 30410: Source Route Bridge.
If you have Source Route Bridge (SRB) running on a
router with at least 1 source route bridge interface configured
and you dynamically disable SRB then add another SRB interface on
another slot, the router experiences a bus error.
CR 26360: PPP.
A router experiences a watchdog error during LCP Configure
negotiation.
CR 24812: TI_RUI.
An IPX ping of 8 bytes causes a bus error to occur on AN, ASN, and
BN routers. The router should log a "does not respond" message
when the MAC address is greater the 6 bytes.
CR 29858: ARE.
The ARE experiences a VBM error when processing a UDP checksum.
CR 28876: DLSw.
When a router receives TEST-P and then TEST-F with an invalid
destination MAC address of 0x000000000000, a bus error occurs.
CR 31926: Translation Bridge.
Translation Bridge (XB) may stop caching RIFs.
CR 29988: APPN.
When you configure an AN router for a GAME buffer size of 1824
(default), an APPN ping of 1500 bytes causes a FAULT (nbase
ASSERT) in the function nba_alloc_inter_msg.
CR 32016: NBIP.
A bus error can occur in the NetBIOS over IP when caching MIB
support is enabled. This failure occurs after you restart or reboot
a slot on a router.
CR 31856: SMDS.
The router is unable to forward IP datagrams to destinations
using an SMDS link when the datagram size (beginning with IP
header and including payload) is exactly 54 or 55 bytes less than
the configured MTU on the SMDS interface of each of the routers.
------------------------------------------------------------------------------
Revision 10.01/7 corrects the following problems:
=============================================================================
CR 29704: LNM.
The Timer Error Report value should be set to 2 seconds;
currently this value is set to 0.3 seconds, which fails to
comply with the 802.5 standard.
CR 28588: Frame Relay.
After bouncing one line of a multiline between Frame Relay switch
and the router, IP routes learned by RIP disappear from the
routing table.
CR 29616: Frame Relay--Multiline.
CR 29617
When you configure Frame Relay for multiline with Random Base
distribution on a router running software version 10.00, IP RIP
uses only one of the Available Data Paths and switches to the
other Data Path if the first Data Path's PVC becomes inactive.
CR 29856: IPX.
A problem exists in routers running software version 10.01 or later
in which IPX static routes are advertised with incorrect costs.
This problem occurs in environments where servers use tick cost to
calculate the expected response time for a connection and
determine retransmission times.
CR 27632: DLSw.
NetBIOS sessions may fail to establish through DLSw if the client
sends the "name query" message to the server's unicast MAC address
rather than to the NetBIOS functional address.
CR 29243: TCP.
If a TCP session does not receive the correct sequence when a
connection is being established, the router leaves the connection
entry in a listening mode. This causes memory to be allocated for a
connection that should be inactive.
CR 29529: OSPF.
OSPF may cause a bus error when bouncing IP in two remote AS
boundary routers.
CR 29654: BF/ARE.
The ARE transmit ATMizer periodically sends a series of cells
that exceed its configured PCR rate. This condition occurs every
5-6 minutes when under constant load.
CR 28165: IPX.
IPX series 10 and higher does not support Novell encapsulation
on a synchronous line. A log warning message appears in the log if
it is configured.
CR 29992: NVFS.
The 6Mb SRAM card from Centennial Technologies does not work with
the BNX or router software.
CR 29201: Translation Bridge.
28829:
When an translation bridge circuit goes down, the learning bridge
forward table is flushed, but the translation bridge RIF cache
remains intact. A new RIF will not be learned until the RIF ages
out (default of 5 minutes), thereby causing AREs to be sent out
until the RIF ages out.
Also, when the LEARN message is sent to the learning bridge, the
the local slot learns the address immediately, causing ARE's to be
sent out until the remote slot learns the address.
CR 29587: BGP.
When you bounce TCP, IP base, or BGP base on a remote router, BGP
fails with an exception vector 2 bus error in
bgp_process_changed_network. The router has learned approximately
1000 routes from its BGP peer.
CR 27185: BGP.
A watchdog occurred in BGP during testing. The router on which
the error occurred was configured with 100 IP routes in its table
and was running OSPF.
CR 29894: Technician Interface.
Ping calculates the average response time by dividing the total
trip times by the number of attempts, not the number of successes.
CR 19992: Technician Interface.
The ping command does not report "service not running" if you use
the -AT or -VINES option and the corresponding service is inactive.
CR 19627: Token Ring.
When generating a source route frame from WALTS that is destined
for a source routing segment on the AN router, the AN router
faults in timac_drv.c line 778.
CR 30266: Source Route Bridge.
A problem exists in router software version 10.01 and later in
which a bus error can occur on a router that has received frames
destined for a frame relay source route interface while that
interface is still initializing.
CR 30080: DLSw.
The ARE will experience the fault "BB Read of Guard page.
Not Valid. VBM error detected" when DLSw is terminated on the ATM
interface on the router. The event log periodically displays the
following message: "TXAP detected a start offset error".
CR 27641: DECnet.
When you change the DECnet cost or priority in dynamic mode on a
PPP line, the router generates faults and a tag violation error.
CR 29633: Frame Relay.
In a Frame Relay environment, if the switch is using Rev1 LMI as
the management type, the packet format will contain the Receive
bit (R-bit) as one of the detail parameters on the address field
of the Frame Relay packet. The R-bit is designed to alert the
router of a congestion state. A customer is requesting that the
R-bit be made optional.
CR 30142: DLSw.
Defining DLS on an emulated LAN can prevent an SNA session between
an IBM host and PC3270 client from passing I-frames.
CR 30440: ISDN.
Bouncing an ISDN BRI interface to a Teleos switch (either DMS100
or NI1) on an ASN router from the Technician Interface causes
SPIDs to be rejected.
CR 29252: APPN.
When you activate an implicit link station with a DSPU and you
configure the corresponding APPN interface to support HPR for
implicit link stations, the hpr_supported parameter in the ls_cb
for this link station is not cleared. When the link
station is
deactivated, the ncs_reset_ls() function faults.
Subsequent attempts to restart the APPN causes disconnects to be
sent to all the devices on the Token Ring.
CR 30539: OSPF.
OSPF interface adjacencies can get stuck in the Exchange state
during the OSPF neighbor negotiations.
CR 30368: OSPF.
After rebooting their AS boundary router, the IP routing table
retains all the valid external RIP learned routes. However,
some AS External type 2 links in the LSDB might be missing.
CR 30418: OSPF.
Changing an interface type from Point-to-Point to Broadcast in
remote mode using Site Manager version 5.01 sets the MIB to
invalid. However, you can perform the same operation successfully
in dynamic mode.
CR 30600: IPX.
IPX may experience VBM errors while processing NetBIOS packets
because IPX is reusing a pointer to a buffer that has just been
sent.
CR 28269: MIB.
tenbasetduplexcongctrl(6) and hundredbasetxduplexcongctrl(7) are
not implemented by wfCSMACDLineCapability, thereby preventing you
from setting ifType and ifSpeed to the appropriate values for full
duplex with a congestion control interface.
CR 30182: ARP.
An HP Probe frame causes a broadcast storm to occur in a looped
bridge network with spanning tree configured.
CR 30723: OSPF.
OSPF externals derived from static routes age out of LSDB after
you reset OSPF.
CR 30702: IPX.
A problem exists in router software version 10.00 or later in which
a router may incorrectly pad an IPX frame that has on odd length
so that it has an even length upon transmission. The length field
in the IPX header remains unchanged, however, the frame contains an
extra random byte at the end. This problem occurs on interfaces
configured for LSAP or for SNAP encapsulation.
CR 29797: ATM.
When you dynamically change ATM attributes, the ATM trunk fails.
CR 29081: GAME.
When a DS3 TX or RX cable (but not both) is disconnected locally
from either the DS3 telco termination point or from the DS3
interface, the DS3 driver fails to recognize that the device is
down and all upper layer protocols (such as, IP) remain operational.
CR 28015: Modem Interface.
A modem fails to answer incoming calls when the RTS and DTR
signals on the console port are in the Mark state. You must
bounce the Console or Modem Enable function to cause RTS and DTR
to transition back into the Space state, at which point it will
answer incoming calls.
CR 30587: PPP.
PPP over multiline stops working, preventing IPCP from
negotiating.
CR 30361: MIB.
A problem exists within the mapping of the external clock speed in
wfSyncEntry to the MIB II equivalent parameter. Normally, when the
clock source is set to external, the clock speed that is shown in
wfSyncEntry.93.* should be mapped over to MIB II's ifEntry.5.*
(clockspeed).
CR 29971: NML.
Corrupted unicast traffic may be transmitted onto a FDDI ring by a
router configured for NML on the FDDI interface.
CR 31005: ATM.
IPX ping fails to respond on an ATM PVC interface after the
initial IPX ping was successful.
------------------------------------------------------------------------------
Revision 10.01/6 corrects the following problems:
=============================================================================
CR 26327: Switched Services.
A dial on demand connection cannot be established on an ISDN BRI
(DMS100) line once the router has lost connection with the ISDN
switch.
CR 27336: SYSL.
Using the SYSLOG feature of router code, the log file gets copied
to a UNIX workstation, but all of the details do not get copied
into the SYSLOG log file in the UNIX workstation.
CR 25634: Learning Bridge.
Bridge traffic filters do not correctly filter NetBIOS multicast
traffic.
CR 27674: XB.
When you configure two interfaces with Source Route Bridge (SRB),
Translation Bridge (XB), and Learning Bridge (LB), an All Routes
Explorer (ARE) received on one interface will cause two AREs to be
forwarded out the second interface. The first ARE is a
straight source route frame, while the second contains the XB
Virtual Ring number. As a result, XB causes an significant
increase in broadcast traffic, which is unnecessary.
CR 28306: ATM.
Disabling and then reenabling the IP base causes a bus error on an
ATM slot configured for Ethernet LAN emulation along with DLSw.
CR 27182: OSPF.
A problem exists in which the router will advertise the external
forward address correctly if the interface to the external has
OSPF enabled and operational. However, if you disable OSPF on that
interface (that is, OSPF is not running on the interface that
the external is pointing to), the external forward address will
still be advertised. The forward address should be 0.0.0.0, not
non-zero, since there is no OSPF running on the interface that the
forward address points to.
CR 27425: ISDN_DRVR.
The fault at isac_host2cop.c line 847 occurs on ASN router
equipped with two quad BRI modules and configured with more than
four BRI leased lines.
CR 25310: ISDN.
A router shows a gradual depletion of free memory when an
ISDN PRI line remains operational, even when the number of lines
is constant and no traffic is being transmitted through the line.
The rate of depletion is about 450 bytes/min. ISDN BRI does not
exhibit this behavior.
CR None: IPX.
A router configured with router software version 9.02 or later
processes SAPS for only one host at a time. The router responds to
each of the hosts sequentially and will not respond to the next
host until the entire SAP table has been set to the previous
host. This creates a problem when multiple requests are received
and the router has a large SAP table.
CR 27758: Translation Bridge.
The frame that the translation bridge sends to the Ethernet
contains invalid data in the LLC header.
CR 27853: VINES.
VINES will experience a memory leak in vines_reassembly_act when
there is a large routing table and several neighbors on the same
LAN are using sequenced RTP updates.
The amount of memory lost and the rate at which it is lost is
proportional to the size of the network, the amount of neighbors
on the LAN and the stability of the network. It is when full
sequenced RTP updates are received that memory is consumed.
CR 27559: IP.
The Enable/Disable IP interface script does not work on multinetted
interfaces. When you issue the command "disable ip circuit
", it disables only the first instance of the
specified circuit. This applies to the Enable script too.
CR 27632: DLSw.
NetBIOS sessions may fail to establish through DLSw if the client
sends the "name query" message to the server's unicast MAC address
rather than to the NetBIOS functional address.
CR 28979: GAME.
bm_buf_dump() checks to ensure that each address is within a page
boundary before proceeding to read a long word. But it fails to
check the address that reads data between pages, thereby causing
the Mid page fault.
CR 28247: Frame Relay.
Routers running router software version 10.0 and later check for a
destination hardware address of the inverse ARP reply packet, and
if it is different from its own hardware address, it drops the
reply.
CR 28696: EZ Internetwork.
If you add an IP address to the BOOTP Client Interface Table that
is not the same subnet as the interface over which the BOOTP
request was received, then EZ-Install fails.
CR 28607: ATM.
Transparent bridging between Ethernet and FDDI over an ATM PVC
does not work when running router software version 9.01 and
later. The router forwards multicast and broadcast traffic (IP
RIP, RIP2, BPDUs) correctly, but not unicast traffic.
CR 28276: OSPF.
A problem exists in which the routing table shows OSPF external
routes with the wrong next hop. This can be seen with two routers
configured back to back over Frame Relay, with one router
advertising the externals to the other router over this Frame
Relay link. The downstream router's routing table will contain
external routes with the next hop of its local FR interface,
thereby preventing the downstream router from communicating to
all external routes learned over this interface.
CR 27543: BOOT.
After you perform a named boot on a BCN router, the ARE processor
will not find the default software image (bn.exe) on same the slot
on which the named boot was performed. The ARE will search all
other slots for the bn.exe image if it cannot find the named boot
image file on the slot from which it originally booted.
CR 28296: BOOTP.
When you set the broadcast bit in a BOOTP reply packet to 1, the
router acting as a relay agent should send out the DHCP message as
an IP broadcast using an IP broadcast address as the destination
address and the link-layer broadcast address as the link-layer
destination address (RFC 1541, Sec 4.1, Droms). However, the
router uses the client hardware address, not the link-layer
broadcast address.
CR 28945: IPX.
The router fails to respond to an IPX GNS or GSQ if the query
comes in over an ATM PVC.
CR 28556: GAME.
A customer requests that users have access privileges for loadmap
to enable those who do not have Manager access to the router
to be able to do loadmaps (especially in light of protocols
unloading on routers).
CR 18964: GAME.
The router causes the log to wrap with the following "mapping"
message:
# 55: 09/20/95 17:46:14.056 DEBUG SLOT 1 GAME Code: 87
mapping [0x31710fd4] of dying 0x02063 @ 0x0badadde survived
(owner=0x00401 @ 0x30089b62, map_act=0x300b6826,
gh=0x3164f150- >0x00002063)
CR 29440: DLSw.
Two Windows NT terminals using NetBIOS to connect to one router
simultaneously select a Lotus Notes server connected via a DLS peer
router. Sometimes one connection attempt times out.
CR 29075: ATM.
ARE E3 Interface needs to set the E3 G.832 Payload Type to "ATM"
instead of "Unequipped" to interoperate with the UT-XC
Italtel-Siemens ATM Switch.
CR 29398: TCP.
A watchdog timeout error, or an "out of memory condition" error,
occurred in routine tcp_get_stm.
CR 27187: Frame Relay.
A router (running 10.01 rev 1) continuously faults when
attempting to initialize a Frame Relay circuit if PVCs are
configured as invalid or inactive and the switch advertises the
PVC as active.
CR 27029: OSPF.
LSDB fails to remove external type 2 routes after they are removed
from the routing table.
CR 29234: NML.
NML still functions after it is dynamically disabled, preventing
bridged traffic from passing.
CR 29290: NML.
When creating an Ethernet interface with bridge and NML configured,
bouncing the interface or bridge will cause a bus error once the
interface becomes active and bridge and NML is operational.
CR 29589: Flash.
ATA Flash sometimes drops a word on large writes (crash dumps on
ARE's).
CR 29384: ARE.
A LANE flush request is not compliant with the LANE 1.00
specification. The source-lan-destination field should be set to
0.
CR 28381: OSPF.
An OSPF Links State Advertisement may be continually retransmitted
every retransmit interval under certain conditions. This does not
cause loss of connectivity, but causes a small amount of
unnecessary OSPF traffic.
CR 28104: IGMP.
When a router receives consecutive LEAVE messages, it repeatedly
sets "group_time_left" to a certain value (default: 12 seconds)
to prevent the group from aging out until the host stops sending
these messages.
CR 26869: DLSw.
When you enter an instance ID in the get wfIpxServEntry
incorrectly, a tag violation occurs because of the incorrect name
length portion of the instance ID used to copy into a fix buffer.
CR 28412: Translation Bridge.
Translation Bridge logs the following messages when it drops the
frames from Source Route Bridge (SRB) because its SAP is not
configured in wfBrXbBaseSaps. SAP 80 is always reported regardless
of the SAP that is actually being dropped.
# 3: 11/26/96 10:14:59 DEBUG SLOT 1 SR Event Code: 106
XB dropping - SAP 80.
CR 29180: Router Redundancy.
A problem exists in router redundancy in which the secondary
router never fails over to the primary router. After the primary
line goes down, the routers proceed to boot as expected, swapping
roles. Shortly after the fail-over, the routers boot again and
continues in a boot-loop indefinitely.
CR 29341: IP.
A router configured with Token Ring ignores OSPF Hello messages
sent with a broadcast address of C000FFFFFFFF.
CR 29024: Learning Bridge.
An illegal instruction error may occur when Learning Bridge is
initializing on a router equipped with a FRE-II that is running
router software version 8.12 or later.
CR 28392: IP.
Source and Destination port added to Detailed Logging feature of
IP traffic filters.
CR 28843: Protocol Priority.
When you enable Protocol Prioritization, it is initialized as the
TCP connection to the router is established. However, because there
are two TCP connections associated with each DLS connection,
it tries to initialize ppri twice, causing a MIB error to occur
the second time.
CR 29796: SWSERV.
The second SPID registration fails after a line failure.
CR 29006: Frame Relay.
Frame corruption occurs while running Frame Relay on a
Transparent bridge between Ethernet and FDDI.
CR 28383: Technician Interface.
A router experiences random faults and slot resets while using
the Technician Interface on an ARE slot.
CR 27613: ATM.
When attempting to join multiple (5)ELANs (on a C100), an HP
ATM Analyzer on the line indicates that the router is not
responding to incoming SETUP's (usually from the BUS) for
approximately 4-5 seconds.
CR 30015: AppleTalk.
A g_fwd fault can occur on a BCN router running AppleTalk on all
slots when a slot gets busy or is reset.
CR None: DLSw/TCP.
Throughput degradation in DLSw TCP file transfers.
CR 29504: X.25.
An X.25 IP local address is disabled when a service record is
deleted even though there are still some service records remaining.
=============================================================================
Revision 10.01/5 corrects the following problems:
=============================================================================
CR 27247:
27251: DLSw.
Dynamically adding a local device to a multidrop SDLC line does
not work.
CR 27052: IP.
IP fragmentation does not work properly when using SNAP
encapsulation over Ethernet.
CR 27418: DLSw.
After you establish an active session across a network and then
delete a local device associated with this session, the
session fails to disconnect (remains active).
This condition occurs with secondary and primary local devices.
CR 27419: DLSw.
An active session running on a local device does not disconnect
when you disable the session.
CR 26125: DLSw.
A Walts script that is driving the automat generates 500 test
polls per second with the destination address equal to that of the
host and a unique source address. After a few minutes of
operation, the router experiences a watchdog error.
CR 27479: DLSw.
A NetBIOS name query is sent through a router to its destination
but the destination fails to respond. Subsequent name queries sent
less that 5 seconds apart are dropped.
CR 26467: APPN.
A tag violation occurs when you attempt to ping a router configured
with APPN over SDLC.
CR 26578: IP.
A problem exist in 10.00 or later where entries in the ARP cache
do not get removed after you change the wfIpNetToMediaType
attribute from dynamic to invalid.
CR 27483: ATM.
An ARE router experiences an VBM error on a slot when routing
between 1577 IP and LANE on the same port and when certain traffic
conditions are present.
CR 27114: TCP.
The router software does not close TCP connections according to the
RFC. This causes problems when interoperating with products
intolerant to variations on the connection close protocol
specified by the TCP RFC.
CR 25918: Switched Services.
In certain situations, the Raise DTR modem will not attempt
subsequent retries if the initial call fails.
CR 17269: BOOTP.
The wfBootpRelayFulEntry interface attributes are zero until
forwarding occurs.
CR 17283: BOOTP.
When you configure a router using Site Manager, the router will
not update the Preferred Server IP addresses.
CR 19940: MIB.
The MIB attribute wfHwEntry.wfMotherBdRev is incorrectly stored in
decimal instead of hexadecimal.
CR 27030: ATM.
If the ARE router receives an LE-ARP that was sourced from an end
station with a MAC address of 000000000000, the router experiences
a bus error.
CR 27568: Frame Relay.
A problem exists in the router code with a Frame Relay direct mode
PVC running software compression. It is possible for WCP to
enter a state where one end of the PVC has WCP in an
operational state (enabled) while the remote end of the PVC has
WCP in a non-operational state (disabled).
CR 23703: AT.
The router experiences a hogs bufs condition that causes it to
reset a slot because it is unable to allocate a buffer.
CR 25452: IPX.
A router running router software version 9.02 and later
will process SAPs for only one host at a time. The router responds
to each of the hosts sequentially and will not respond to the next
host until the entire SAP table has been sent to the previous
host. A problem can exist when multiple requests are received and
the router has a large SAP table. Even if a Get Nearest Server
request is received, it will not be responded to until the General
Service Query has been responded to.
CR 22465: PPP.
SHOW PPP commands do not display correct information for HSSI
circuits if you have configured a multiline for a PPP circuit and
configured at least one PPP circuit over a HSSI.
CR 26912: PPP.
An error exists in scripts associated with router software version
8.12 and later. This error prevents you from accessing the MIB
variable wfHssiEntry.wfHssiActiveCct when you run the SHOW PPP
CIRCUITS command on a HSSI interface. This problem occurs because
the MIB entry wfHssiActiveCct does not exist.
CR 27608: BOOTP.
Unable to set MIB variables for BOOTP in MIB version 9.00 for
the MIB object wfBootpClientIntfEntry.
CR 27188: VINES.
The router experiences a bus error when configuring VINES inbound
traffic filters on a synchronous interface. VINES interface never
recovers.
CR 26812: OSPF.
OSPF faults after experiencing a bus error in ospf_extern_comp().
This problem exists only when the router has route policies
configured to ignore OSPF external routes.
CR 27665: Spanning Tree.
When two routers are interconnected via ATM and Spanning Tree
is configured on these circuits, the blocking circuit never
establishes a steady state. The blocking circuit repeats
the cycle of blocking, listening, learning, and forwarding.
CR 25087: IP.
When configuring an IP traffic filter to accept destination TCP
port 23 (Telnet), and to drop all other TCP ports, the accept
filter does not get executed. This problem is specific to the ARE
router.
CR 27595: OSPF.
Information in the MIB indicates that the primary and backup
soloists are running on the same slot when in fact they are
running on different slots.
CR 26293: Technician Interface.
The help for the log command contains no mention of the -x
argument.
The "log" command in the Technician Interface contains a feature
that disables the logging of events (as opposed the display of
the logged events). This is accomplished by using the -xargument to
the log command, in combination with other arguments, such as
-e, -s, -f, to specify the events being
disabled.
CR 27620: ATM.
After telnetting into an ATM slot (ARE/0C3) and attempting to
disable or enable an Ethernet circuit on another slot (for example,
disable csmacd conn 1.1), the ATM slot fails with an exception
vector 5 - VBM error recorded in the event log.
CR 27822: DLSw.
When DLSw builds a XID-F based on the received XID-P, the XID data
is copied to the LLC header portion of the buffer rather than to
the position following the header.
CR 27972: SNMP.
The router will attempt to generate authentication failure traps
when queried by network management stations that support the
SNMPv2C protocol. SNMP should just discard the message and
increment snmpInBadVersions.0.
CR None: SDLC.
A link station fails to connect after deleting a local device and
adding a new local device.
CR 27938: Protocol Prioritization.
Non-SNAP and IP traffic (for example, OSI and SNA BNN) are not
filtered correctly when looking for a specific NLPID, or when a
user-defined filter is based on the FR_MPE reference point.
The FR_MPE reference point was being initialized only for SNAP
encapsulated frames.
CR 21979: TCP.
During IPEX testing of flow control through TCP it was determined
that the xmit echo sequence counter was being updated locally and
not from the remote TCP peer. This caused the local peer window
to open and the remote peer window to close.
CR 22005: TCP.
When the client acknowledges received data, TCP does not
consistently send a window acknowledgment back to the peer. This
causes the transmission of data to stop.
CR 22007: TCP.
TCP window update is not passed to IPEX client consistently.
Apparently, TCP is waiting to be polled by the client.
CR 22009: TCP.
TCP was incorrectly fragmenting packets transmitted from IPEX.
CR 22012: TCP.
When the TCP sending client tx window is full, data is fragmented
and data loss is detected by the receiving client. This results in
a client fault at the receiving end.
CR 22016: TCP.
TCP will intermittently retransmit message blocks continuously, and
remains in this retransmission loop. In this state, TCP does not
pass data to the client.
CR 22019: TCP.
TCP will retransmit multiple messages simultaneously, thereby
consuming the majority of the bandwidth on the WAN link.
CR 22446: TCP.
The router faults at the remote TCP connection when packets whose
size is 64 bytes or less are transmitted to IPEX.
CR 23899: TCP.
A fault occur occurs in "error in tcp_xmt.c at line 366" when the
remote wfSyncEntry is bounced and data is being passed.
CR 24916: IPEX.
The router faults with the following TCP error: "error in
tcp_xmt.c at line 366".
CR 26654: DLSw.
A TCP connection in 11.00 rel was consuming more memory than
required.
CR 28072: Source Route Bridge.
A router configured to run source routing bridge (SRB) with SRB
traffic filters may drop Specifically Routed Frames (SRFs)
randomly.
CR 27536: IP.
IP consumes all local memory when pinging through a router to a
non-existent IP addresses. For instance, this problem could occur
if a network management workstation ping all IP addresses within
a subnet.
CR 28067: SYNC.
If you configure a BCN router for Standard WAN protocol and set
the wfSyncEntry.wfSyncLocalAddress and/or the
wfSyncEntry.wfSyncRemoteAddress MIB object to 48 or greater, a bus
error will occur when you run the embedded SHOW SYNC scripts.
CR 28134: ST2.
ST2 connection bandwidth allocations will not be cleaned up when
only one line of a multiline circuit goes down.
CR 27402: Frame Relay.
When running partial frame relay switch, loss of a physical or
logical link goes undetected.
CR 28039: LLC.
When you dynamically delete a 11c circuit that you configured with
Frame Relay, a bus error occurs.
CR 27533: ATM.
A problem occurs in 10.01 rev 3 in which an ATM slot resets under
heavy traffic conditions and under heavy CPU utilization.
CR 25558: OSPF.
OSPF adjacency sometimes gets stuck in state loading after
rebooting.
CR 27005: OSPF.
A router running software version 10.00 code in an OSPF
environment in which other routers run 8.12 code may choose a
higher path cost route over OSPF point-to-point interfaces. This
may cause the router to use non-optimal routing paths.
CR 28003:
CR 28186: Learning Bridge.
Adding a Bridge Forward_to_cct filter onto an ATM PVC can cause
the router to discard the traffic being transmitted through this
filter. The filter count will increment but it will never make
it to the circuit to which it is being forwarded across the
backplane.
CR 27651: IPX.
The IPX routing tables show incorrect routes or routes with
inflated costs.
CR 27866: OSPF.
In an OSPF multiarea environment, some networks from one area may
not be visible in the routing tables of routers in other area(s).
CR 27900: AT.
A problem exists in the 10.00 router code that prevents AURP
from forwarding traffic after introducing a network change that
would force one AURP tunnel to go down and another to take over.
This results in loss of AppleTalk connectivity.
CR 28153: Technician Interface.
When running SHOW CIRCUIT STATS when specifying one individual
circuit, a tag violation occurs on the slot on which the circuit
resides.
CR 28200: OSPF.
An Area Border Router may fail to properly summarize routes when
attached to more than two areas. This occurs because their type
3 network summaries had been managed incorrectly.
CR 28296: BOOTP.
When you set the broadcast bit in a BOOTP reply packet, the router
as a relay agent sends the packet with an IP broadcast address
(which is correct) and the client hardware address (which is
incorrect; it should be a broadcast address according to RFC
1541).
CR 28781: DLSw.
If a DLSw/TCP connection gets congested, it will issue an
"ENTERBUSY" signal for the connections which need to send data.
When the congestion has abated, DLSw should issue an "EXITBUSY"
for all connections it put into "ENTERBUSY". If there are more
than 20 connections put into "ENTERBUSY", the router will fail to
bring the 21 connection out of EXITBUSY. The connection remains
like this until the client is reset.
CR 25351: DLSw.
When a DLS Mac entry is cached (for example when a test poll was
received from that MAC address), creating an instance of
wfDlsDefaultMacEntry for that MAC peer address causes a fault.
CR 27299: DLSw.
When you dynamically delete a DLS default NetBIOS peer instance,
errors occur in mib_ent.c.
CR 27806: IP.
An X.25 IP-peer (adjacent host) is unreachable after X.25 packet
level was down in an OSPF environment in which the OSPF type for
the X.25 IP interface is Point-to-Point or Point-to-Multipoint.
As a result, the OSPF neighbors cannot exchange their tables.
CR 28364: OSPF.
OSPF Adjacencies over PtoP (or PtoMP) will remain FULL after
bidirectional connectivity is lost.
CR 28423: Telnet.
Under heavy load conditions, TCP may fail to register TCP clients
for certain IP interfaces once the interfaces become active.
CR 27088: Technician Interface.
Enhancement request to use a wildcard to shorten the list of

When you configure multiple tunnels, AURP will forward
AppleTalk frames out the wrong tunnel.
------------------------------------------------------------------------------
Revision 10.01/4 corrects the following problems:
=============================================================================
CR 26102: IPX.
A router configured with NetBIOS static routes in a hub and spoke
environment does not forward traffic. These IPX encapsulated
NetBIOS packets, which are broadcast from spoke router to spoke
router, are dropped because the network address of the receiving
interface is contained in the list of network addresses resident
in the packet.
CR 26690: Switched Services.
A fault condition in map_rem.c occurs if a slave router receives
a call via Dial Backup while a Primary Direct Mode PVC line
still exists. This condition causes the IP interface on the
specific Direct Mode PVC to remain inactive until you restart the
physical interface.
CR 25480: IPX.
A 16-character server name in the IPX encapsulated NetBIOS packet
can cause the name matching routine to fail.
CR 25968: TCP.
Enabling and disabling TCP may place the TCP connection
in a closed state, from which it never recovers.
CR 25291: MIB II.
The fainter MIB object contains two attributes, affinities and
ifOutOctets, which do not contain the correct information when
corresponding to a multiline circuit where the circuits are
on different slots. The value for the ifEntry object should be
the aggregate of both the synchronous interface
statistics contained in a multiline interface.
CR 26687: MIB II.
While using the SNMP manager, the MIB-11 attribute ifEntry.5
(speed) does not return the aggregated line speed of a
mulcting circuit.
CR 27489: Switched Services.
A bus error occurred after the primary circuit in backup mode is
terminated on the slave side.
CR 27243: Loader.
When unloading run.exe and sh_ip.exe simultaneously from the same
slot, the router experiences the following error:
Error: exception vector 2 - Bus error OR (2) Watchdog expired,
service terminating.
This condition occurs after automgr.bat or autouser.bat is
loaded on a slot and the SHOW IP routes (embedded script) is
executed via a Telnet session. If the Telnet session if forced to
terminate prior to the completion of the SHOW IP routes script,
the slot configured for IP in the Telnet session faults.
CR 22142: IP.
The router may generate an error in IP_rt_cache.c at line 245
when you attempt to add IP routes.
CR 26637: IP.
FTP may hang when transferring data over slow links.
CR 26872: IP.
When you delete a circuit configured with IP and TCP, the router
faults when no other circuit on that slot is configured with IP.
CR 26943: DVMRP.
Mutilates storms occur when traffic arrives over a tunnel that
you have configured and there is no route through which to
transmit the traffic, or the traffic is destined to be transmitted
out the wrong interface. This condition should cause the router to
drop the traffic, but instead the router floods the
traffic out all interfaces, including the tunnel itself.
CR 27039: MCT1E1.
If the router sends inverted data to a QMCT1 and you reset the
slot, the port will remain in a red alarm state.
CR 27120: DLSw.
SDLC tests on the DLS hurdle consist of a BLN router connected
to APPN HOST BLN via DLS over Token Ring. SDLC cannot
establish a link with DLS, causing all three (3) SDLC-related tests
on the DLS hurdle to fail.
CR 27017: Switched Services.
A router configured with a primary line and a dial back-up line
may cause Dial Backup to fail because the secondary line may never
dial the modem should the primary line fail.
CR 27117: Switched Services.
The dial backup master configured on an IN router may fail to dial
the modem on the first attempt.
CR 27212: OSPF.
The wfOspfGeneralGroup.wfOspfPrimarySlot.0 can report the
incorrect primary OSPF soloist slot after OSPF bounces.
CR 27240: DECnet.
After configuring DECnet on the router, modifying any interface
parameter leaves the DECnet interface in a down state from which
it never recovers.
CR 27045: FTP.
The FTP command displays the wrong command entries.
CR 25618: Technician Interface.
When issuing the SHOW CIRCUIT BASE command, the Technician
Interface enters into a loop condition in which it displays
circuits on the screen repeatedly until you intervene.
CR 25635: Technician Interface.
The SHOW CSMACD BASE CIRCUIT command does not list circuits if
you change the circuit name from its default name.
CR 27237: IPX.
IPX does not filter a network address of 0. For example, if the
source network address of a packet you specify is zero, and
a traffic filter is created for network zero, the router ignores
the traffic filter.
CR 27470: IPX.
System performance degradation may occur because the "lost route
algorithm" was executed unnecessarily.
CR 27055: IP.
If the sending host sends multicast data with the IP fragment bit
set, the IP-forward-to-IP-address filter does not retain the
IP fragment bit, and assigns different IP sequence numbers.
CR 26885: IP.
After booting the router, several OSPF routes were missing from
each slot, except for the OSPF soloist slot. During the route
update process, IP may have skipped over a group of routes
because its RNP queue was being modified before IP completed
processing all routes.
CR 25842: IP.
Host entries may fail to display when the wfIpNetToMedia MIB table
is queried.
CR 27005: OSPF.
A router running router software version 10.00 code in an OPSF
environment in which all other routers run 8.12 code chooses a
higher path cost route. This may cause the router to use
non-optimal routing paths.
CR 27474: VINES.
VINES experiences a bus error when it unsuccessfully attempts to
allocate a buffer and then attempts to free the same buffer.
------------------------------------------------------------------------------
Revision 10.01/3 corrects the following problems:
=============================================================================
CR 24365: DLSw.
A new DLSw feature has been introduced that will allow you to
enable or disable NetBIOS session alive frame transmissions.
Previously, a NetBIOS session would always transmit session alive
frames over DLSw every 30 seconds. These session alive frames
could cause lines to remain active unnecessarily, possibly
increasing the usage cost of the line.
Use the Technician Interface to enable or disable NetBIOS session
alive frame transmissions. To enable the NetBIOS session alive
filter, stopping session alive frame transmissions, issue the
following Technician Interface command:
set wfDlsNetbiosSessionAliveFilter.1
To disable the NetBIOS session alive filter, allowing session
alive frame transmissions, issue the following Technician
Interface command:
set wfDlsNetbiosSessionAliveFilter.2
CR 24662: LAN Bridge and Source Route Bridge.
If a router encounters a slot disconnect, all bridge traffic
generated between the affected slots will terminate.
CR 25986: TCP.
When a client issues a Telnet session to a network address of
which the router is a subnet, the router attempts to establish a
Telnet session, but the local memory allocated to this process is
never returned when the session ends. The log clearly indicates
the Telnet/TCP session initializing, but does not indicate that
the session has ended. As a result, a memory leak occurs.
CR 25956: IPX.
The initiation of IPX RIP and SAP updates are staggered so that
SAP updates start after a time delay of half the RIP update
period. If you fail to configure RIP, then the value used to
initiate the SAP updates may be incorrect, thereby preventing SAPs
from being sent.
CR 21151: DVMRP.
In a route loop topology, the non-dominant router rejected routes
on the wrong interface.
CR 23779: DVMRP.
In a route loop topology, the non-dominant router accepted the
multicast data from its dominant router and deleted the cache
entry on the correct VIF, thereby causing DVMRP to fail.
CR 24985: DVMRP.
A nexthop address of 0.0.0.0 sometimes appears in the DVMRP
routing table, thereby causing DVMRP to fault.
CR None: LLC.
The presence of the g_timer_get_read() variable caused the timer
to expire prematurely which led to the transmission of multiple
SABME's. This condition caused sessions to disconnect.
CR 23215: MIB II.
A problem in the router code causes indexing errors to occur
in Frame Relay direct mode PVC's. This problem affects network
management stations in particular, which are unable to correlate
IP addresses to their corresponding Frame Relay direct mode PVC's
in network management maps.
CR 26404: Switched Services.
An incorrect line in the router code causes a flag to be set
that erroneously indicates that the modem is down when it is
in fact operational.
CR 26441: BNX SWITCH.
A T1 port can be suspended in a loopback state. The only way to
disable this state is to bounce the port.
CR 26296: DLSw.
A router configured on a Token Ring network receives a test frame,
which it sends as a CANUREACH to the router's DLS peer.
The peer sends an LLC test poll explorer frame as a single-route
broadcast (STE) only. A MIB variable has been created that allows
you to send STE's or ARE's (all-routes explorer frames) to each
interface.
CR 26487: DVMRP.
The router will accept route updates from an unknown neighbor
provided the source IP address of the update resides on the
correct network. DVMRP should not send route updates
before sending probe packets, and DVMRP should not accept route
updates from an unlearned neighbor.
CR 23695: DLSw.
When you deactivate the line from the host, and then reactivate
it, the DLSw connection to the controller does not come up. The
log shows the disconnect message transmitted out to the AN router,
but fails to show the router's response. To activate the line, you
must bounce DLSw on the remote AN.
CR 26222: SDLC.
Bus error in sdlc_disconnect_send_msg on slot 8 during scaling
testing where there were 12 primary SDLC devices per port on all
ports. This bus error would repeat every 3 to 20 minutes.
CR 26791: DVMRP.
The non-dominant router sends a graft upon receipt of a IGMP host
join message. This results in duplicate packets being forwarded
to the LAN.
CR 26825: DVMRP.
Bay Networks routers do not accept route updates from unknown
neighbors. Because Cisco routers do not send DVMRP probe messages
over a tunnel, Bay Networks routers will drop all route updates
and multicast traffic transmitted from the Cisco routers. A switch
must be added to allow accepting route updates from unknown
neighbors.
CR 26853: DLS.
A recovery problem occurred after disconnecting/reconnecting the
SDLC lines to the PU or the host on an SDLC-to-SDLC connection.
CR 26842: MCT1.
MCT1 module faults with multiple bus errors and fails to recover
when attempting to boot LN routers.
CR 23288: IGMP.
A fault occurs in igmp.misc.c when attempting to create a new
IGMP interface.
CR 24875: Source Route Bridge.
When the router switches to the backup line and then later
switches back to the primary line, source route frames get
dropped.
CR 26885: IP.
After OSPF goes down one slot and comes back on another slot,
some IP routes may be missing on one slot (the old OSPF soloist
slot), and all other slots are pointing to the old OSPF slot as
the author of that route.
CR None: Frame Relay.
Frame Relay-ATM network interworking required support allowing many
DLCI's to map to the same VCID.
CR 25885: DLSw.
CR 25929 A bus error occurs when attempting to establish a DLS/SDLC
connection to one particular link station. This condition can be
attributed to the configuration of a duplicate local device.
CR 26593: DLSw.
PUs can fail to activate in a manner that results in
NCP status code PAPU2 after you execute a prescribed sequence
of actions. This sequence of actions can be cleared only by
a NetView operator.
CR 25849: SDLC.
The primary FRAD inexplicably fails to issue DISCs to all
configured remote devices. For example, when you configure 3 PUs
with link station addresses 01, 02, and 03, the FRAD initially
sends DISCs for all three, but after all three failed to respond,
FRAD stops sending DISCs. Then when 03 eventually responded, the
FRAD still failed to send a DISC for it. Resetting the slot caused
the FRAD to begin sending DISCs for PU 03, but not for 01 and 02.
CR 26919: SDLC.
In the below network, PC3270 sessions fail to recover
after disabling and enabling the wfSyncEntry instance for the
Frame Relay port on a router configured with Primary SDLC
ports. This problem occurs because the remote/primary SDLC router
does not send out the XID null frames onto the Frame Relay line and
the host/secondary SDLC router does not send out a DISC request
to the host after the frame relay port on the host router notices
that the primary router stops polling the host router.
host remote
host -- sdlc -- router --- FR 1490 --- router -- sdlc -- PCs
CR None: SNMP.
When setting multiple VARs in one PDU that includes display
strings, the SNMP agent sets the value of the strings to the
correct length, but truncates the last three to four bytes.
CR 26192: MIB.
The configuration file for the ASN router (ti_asn.cfg) supplied
with all versions of 10.00 (rel through 10.00 rev4) has a 9.00 MIB
version.
CR 26364: APPN.
You cannot enter a host name consisting of 17 characters
when issuing an APPN ping at the Technician Interface prompt.
You should be able to enter up to 17 characters for an APPN
host name.
CR 25123
CR 23427: DLSw.
A bus error occurred in dls_flow_tcp_busy after disabling DLS
on a remote router. The remote router is a BCN. The BCN's SDLC
lines are configured as Primary. This error occurs if there is no
configured slot IP address in DLS.
CR 27063: DLSw.
The router generates the following log message too frequently:
"received an SSP command in TCP local"
CR 27087: IPX.
An ARE router constantly resets when IPX is configured within any
ATM Service Record. The problem has been seen in both a PVC and
LANE configuration where IPX is configured on the ARE and at least
one other slot on a BLN or BCN router.
CR 26440: DataPath.
Successive attempts to disable and re-enable Learning Bridge
causes the router to eventually fault because of insufficient
memory. This problem stems from a memory leak in the routine
dp_cc_op_act.
CR 26924: DLSw.
The router code corrupts DLSw data packets during periods in which
the buffer depletes its memory. The packets become corrupted when
the 16-byte DLSw data frames get inserted between the end of the
TCP header and the start of the DLSw data. This condition causes
the receiving routers to experience tag violations.
CR 27140: IP.
A problem occurred when routers running OSPF learned the same
external network with two different masks (the more specific mask
learned by RIP being injected into the OSPF cloud; the less
specific mask via a static route). Then when the RIP network is
disabled, the more specific route gets flushed out of the
OSPF lsdb, and IP points to a disabled interface as the next valid
hop.
CR 26129: MIB.
Problem occurred when attempting to open an 8.12 config file
(with a MIB stamp of 8.10) with SM 4.01/rel in local mode. Problem
exists on both PC/Windows and UNIX SM platform.
Added support for the following IPX MIB attributes to ensure
backward-compatibility for the Site Manager IPX MIB.
wfIpxBaseNetSizeBoundEn
Allows you to enable or disable the maximum allowable size of the
network table.
wfIpxBaseMaxNetTblSize
Allows you to specify an integer that determines the maximum
allowable size of the network table.
wfIpxBaseNetTblFillNotify
Allows you to specify an integer from 1 through 100 that
notifies you when (configured) percentage is reached.
CR 20940: Redundancy.
A router experienced a bus error when Router Redundancy received
corrupted frames and attempted to process the frames as multiple
Router Redundancy PDU fragments along with SNMP frames.
CR 26268: BNX Switch.
Congestion control was not setting FECN and BECN on trunks
correctly.
------------------------------------------------------------------------------
Revision 10.01/2 corrects the following problems:
==============================================================================
CR 26969: DLSw.
Test polls generated by running a TCL script in a dual switch
DLS network causes the router to fault with tag violations.
-----------------------------------------------------------------------------
Revision 10.01/1 corrects the following problems:
==============================================================================
NOTE: Revision 10.01/1 incorrectly referenced CR 25249. The correct CR
number is 24249, as documented in the 10.01/1 revision notes.
-----------------------------------------------------------------------------
CR 23065: IP.
Attempting to boot an ASN router configured for IP host-only may
cause a tag violation to occur.
CR 25483: Switched Services.
The router fails to redial if the first connection attempt times
out before the DCE asserts DSR, but after receiving a connection
indication (CNX) from the DCE.
CR 26247: APPN.
APPN attempts to connect to a link station 10 times (its fixed
limit) before it times out. This problem occurs with APPN over
SDLC when SDLC tries to bring up the link station 10 times before
timing out and alerting APPN. If APPN reaches its limit of 10
retries, it deletes the link station.
CR 26452: GAME.
A g_fwd may fail before the slot has discovered that the remote
slot has gone down. This results in a panic as the sending slot
thinks the remote slot should have received the buffer because
it is still in its slot mask.
CR 25591: Translation Bridge.
RIF entries on a Token Ring segment may fail to age properly.
CR 24346: Translation Bridge.
Disabling the Translation Bridge base results in bus errors when
transferring files back and forth to an end station on an
Ethernet segment from an end station on a Token Ring segment while
multiple SRF's are being received simultaneously.
CR 18837: BOOTP.
In a multinetting environment, the router chooses the last address
added to the multinetted interface as the BOOTP gateway. If you
disable BOOTP for that address, the router continues to use this
address as the BOOTP gateway instead of selecting the next
address in the network configuration as the new BOOTP gateway.
CR 25126: MCT1E1.
The Munich driver mail may fail to transmit all frames, except
interrupt queue frames on the priority queue. This problem occurs
only on logical lines with high error rates.
CR 24714: OSPF.
When you configure two AN routers across a synchronous interface
with a MTU size of 4608, OSPF adjacencies can take up to 20
minutes to form. The AN router receiving the Data Base Description
packets remains in the loading state while the router sending this
information will be in the full state.
CR 19711: Scripts.
The SHOW HARDWARE SLOT command generates too many columns on a

CR 19688: DLSw.
DLSw drops non-NameQuery/NameRegisterNetBios broadcast frames that
a router receives in a short interval because of the nature of its
caching system.
CR 22792: IP.
Within IP traffic filters, for any rule that has a log action,
the router logs an entry. Only the rule with the highest
procedure should be performed.
CR 23340: LLC.
The router may fault with the following error during a test poll
storm:
"Error in Buffer.c at line 157"
CR 24142: IP.
The router faults after receiving corrupted ICMP packets that have
an IP length that exceeds 65,000 bytes.
CR 25569: DLSw.
A Windows NT/NetBIOS session may randomly fail to establish through
DLSw whenever the server and the client pick up the same local
session ID for the session they are attempting to establish.
CR 25656: GAME.
The first day of each month the clock on the AN router shifts by
one extra day. As a result, the Frame Relay circuit on the router
disconnects, preventing the router from sending LMIs to the
switch. This condition also has caused the clock to stop
temporarily.
CR 24249: FRE-2.
If you plug an incorrect console cable/connector into the SRML
module of a running BN router, the LED's located in the front of
the FRE's suddenly stop blinking, indicating that the router is
inoperable. The lights resume normal operation when you remove
the console connector.
CR 25844: DLSw.
Playing a test poll storm in a dual switch configuration
causes a watchdog to occur on the adjacent router.
CR 24048: LNM.
An IBM LAN Network Manager station intermittently fails to
establish a link to a Token Ring interface. This situation occurs
only when the Token Ring interface was previously linked and then
unlinked from another LNM station.
CR 24049: LNM.
When unlinking an IBM LNM Manager from a Token Ring interface,
the router generates incorrect LNM link status for the MIB variable
wfLnmInterfaceEntry. When you unlink the LNM station,
the LNM link status should reflect a "nil" value, rather than
retain the previous MAC address of the IBM LNM Manager station.
CR 25418: DLSw.
When you issue a "get wfDlsSlotEntry.*.5" command from the
Technician Interface, the router generates invalid information
for the MIB variables .wfDlsCurrentMemory and .wfDlsHiWaterMark.
CR 25805: NVFS.
Compacting Series 2 Flash cards (especially Epson Seiko Flash
cards) can occasionally corrupt file systems.
CR 25956: IPX.
IPX may stop sending IPX SAPs if you have not configured IPX RIP.
CR 24311: IPX.
If IPX tries to send IPX update messages to busy slots, it may
fault because of a g_fwd failure.
CR 25867: DLSw.
A router running with hundreds of DLS connections may fault with
the following error because a buffer is being freed erroneously:
"Error in Buf.float.c at line 114"
CR 24821: X.25.
When X.25 processes a connect indicate and you have not enabled the
flow control negotiation parameter, X.25 rejects all facility
code. The flow control negotiation parameter is limited to
packet and window size only.
CR 26107: Frame Relay Switch.
Excess burst is not being calculated correctly, causing frames
that exceed excess burst to be dropped at the ingress; the
data does not exceed excess burst. Excess burst
uses the large default that should never be exceeded.
CR 26139/
25737: Frame Relay Switch.
When one Navtel is configured to send packets at 256 bytes, and the
second Navtel has a packet size of 32 or lower, the traffic
stops. Traffic resumes when the packet size is increased to a
value of 64 or higher.
CR 26118: Frame Relay Switch.
When creating multiple mappings for the MIB attribute
wfCctOptsCngcEntry, the first map fired and deleted all the
structures and the second map tried to use invalid memory. This
caused a tag violation to occur.
CR 25846: OSPF.
After OSPF's Dykstra algorithm runs for 65,535 tries, OSPF faults
with the following message: "LSA in UNEXPECTED STATE".
CR 26163: MCT1E1.
When selecting an unused QMCT1 or DMCT1 interface in Site Manager,
the Link Module Fail LED lights up. When you reboot the router,
the fail LED's on both the QMCT1 and Dual MCT1 link modules turn
off.
CR 25900: MCT1E1.
On a router configured with IP over PPP, with 64-byte packets
using one slot with 48 logical lines, the QMCT1 is unable to
utilize 85 percent of the 128K line.
CR 26230: DLSw.
If SDLC secondary disconnects, and the router reaches a
CANUREACH state during this period, DLS never reestablishes.
CR 25351: DLSw.
When a DLS MAC entry is cached (for example, when a test poll was
received from that MAC address), creating an instance of
wfDlsDefaultMacEntry for that MAC address may cause the router to
fault.
CR 20516: LLC.
Disabling a DLS interface on a Token Ring network while it is
transmitting and receiving DLS traffic causes a watchdog timeout
to occur in llc.
CR 21715/
22160: DLSw.
A watchdog timeout occurs in DLS after disabling the DLS base
record. If you have multiple SAPs configured (for example, all 127
possible SAPs), DP takes too long to deregister SAPs when DLS
shuts down.
CR 23591: DLSw.
Establishing a DLS over SDLC connection may take a long time
because of a delay in the transmission of CANUREACH.
CR 24959: MCT1E1.
When listing the instances of the MIB variable
wfDs1E1BertStatsEntry, the listing succeeds intermittently for
port 1 but fails to succeed for subsequent ports.
CR 25119: MCT1E1.
When a primary clock is lost on a QMCT1, the router fails to
initiate the secondary clock on port 3.
CR 25255: Hardware Compression.
The driver faults when it mistakenly determines the state of the
rings as hung when the rings are functioning properly.
CR 25096: MCT1E1.
The QMCT1 port 1 primary clock was changed to an external clock.
However, there is no external clock connected. Therefore,
port 1 clocking should revert to the secondary clock but does not.
CR 24161/
CR 25120: Bisynchronous.
The Bisync/BOT code does not handle a DLE-DLE combination
correctly within transparent text.
CR 23255: DataPath.
When running a bridge storm (bridging loops without Spanning Tree),
a slot may reset with an "out of memory" error or a watchdog timer
error.
CR 25443: FDDI.
A hardware problem can occur when the state of a protocol is
"down", but the state of the interface is "up". If you monitor the
FDDIEntry, the Tx stats continue to grow while the Rx no longer
increments. If you perform a packet capture on Rx on this
interface, the trace will show that packets are being received,
but unacknowledged. This condition can be caused by hardware
corrupting information in the Ring Descriptors, which causes the
interface to hang and never recover.
CR 25473: DLSw.
Link stations do not recover when a Frame Relay cable is
disconnected and connected again.
CR 24918: GAME.
A new Autosave log feature has been implemented on LN routers
that allows users to automatically save the log to the Flash card
or floppy drive when the log is about to wrap. This new feature
prevents the log information from being lost.
You can enable the Log Autosave feature from the Technician
Interface only.
The Log Autosave feature requires that you set two new attributes
in wfSerialPortEntry object: wfSerialPortAutoSaveNumFiles and
wfSerialPortAutoSaveVolume. The wfSerialPortAutoSaveNumFiles
attribute allows you to specify a value that determines the number
of times a log will be saved when it wraps. Specifying a value of
0 disables the feature; 0 is the default.
The wfSerialPortAutoSaveVolume attribute allows you to specify
a volume number ("2:"), or a volume name ("a:"), which determines
where you want logs to be saved. Specifying a colon after the
volume or volume name is optional.
On a BN platform, there is only one instance of the
wfSerialPortEntry object. Therefore, you will need to specify the
attributes described above for this instance.
On an ASN platform, there are 4 instances of wfSerialPortEntry,
each corresponding to a possible slot. You can configure the
feature on only one of the instances corresponding to an existing
slot.
On an LN platform, there are also 4 instances of wfSerialPortEntry.
Enable the feature on the first instance, which should correspond
to the console port (wfSerialPortEntry.wfSerialPortName.1 =
"CONSOLE").
The log gets saved in a file named "auto.log", where is a
number from 1 to the number you specify in
wfSerialPortAutoSaveNumFiles.
The logs will be saved until the number of logs reaches
wfSerialPortAutoSave\NumFiles, or until the Flash card or floppy
drive is full.
Wrapping a log on any slot automatically saves the log.
CR 25335: DVMRP.
A watchdog error can occur in DVMRP if some DVMRP interfaces are
being dynamically configured while other DVMRP interfaces are
learning multiple routes.
CR 25499: DLSw.
After activating flow control, traffic flow of the remaining
unsent frames will be sluggish after the traffic congestion
is rectified.
CR 23216: SDLC.
When deleting a primary SDLC circuit and then reconfiguring it,
DLS connections will not recover.
CR 25065: AN2.
An enhancement request has been issued to allow non-Token Ring AN
routers to support buffer sizes similar to the Token Ring AN's.
You can set buffers sizes on non-Token Ring AN routers to 1824 or
4800 bytes. This setting will be saved in NOVRAM and will be read
in at boot time.
Buffers can be carved by issuing the following set commands from
the Technician Interface:
set wfKernCfgParamEntry.wfKernCfgParamDelete.1 1
set wfKernCfgParamEntry.wfKernCfgParamBufSize.1 4800 (or 1824)
set wfKernCfgParamEntry.wfKernCfgParamDelete.1 2
commit
reset 1
To return to the default buffer sizes, enter the following
set command from the Technician Interface:
set wfKernCfgParamEntry.wfKernCfgParamBufSizeReset.1 1 ; commit
*** We recommend that you follow the above steps in the order in
which they appear. We also recommend that you delete
instances of wfKernCfgParamEntry before saving the config.
This process is similar to carving local/global memory
partitions.
When you set wfKernCfgParamEntry.wfKernCfgParamBufSize.1, the
buffer size gets saved to NOVRAM. At boot time, this setting
determines the buffer size.
CR 23172: IPX.
IPX accepts broadcast packets with an incorrect destination
address and tries to forward them.
CR 25212: Frame Relay.
Access Circuit does not recover after you pull a cable out and
plug it back in when the management type is NONE.
CR 24049: LNM.
When issuing the SHOW LNM LINKS command or viewing the MIB
(wfLnmInterfaceEntry) for LNM, the router displays incorrect
information about LNM link status after unlinking an IBM LNM
station.
CR 23288/:IGMP.
CR 23783 A fault occurs in igmp.misc.c when attempting to create a new
IGMP interface.
CR 25742: Frame Relay Switch.
A typographic error occurs in the translating tool, add2base. The
second description for each time unit should be Tx not Rx. For
example, for time unit 13, the description should be
StatsDcLbcTxMaxDelta13 not StatsDcLbcRxMaxDelta13!
Circuit (cct) number 8 (0x8)
StatsDcLbcRxMaxDelta13 448
StatsDcLbcRxMaxDelta13 508 <-----
StatsDcLbcRxMaxDelta14 448
StatsDcLbcRxMaxDelta14 508 <-----
CR 25399: Frame Relay Switch.
The add2base tool did not comply with channel assignment
requirement.
CR 25777: DLSw.
A session cannot be re-established after disabling and
then enabling DLS on an interface.
CR 25727: Frame Relay Switch.
The DE bit has not been set properly after the circuit has been
idle for a while. A Frame Relay circuit is up and passing traffic
and traffic is stopped for a period of time. When traffic resumes
at line rate (128k) and CIR is set low (10k), a certain
amount of traffic will be passed before the DE is set. The amount
of traffic allowed through before setting DE is directly
proportionate to the amount of time the circuit is idle.
CR 24378: OSPF.
When the OSPF backup soloist transitions from backup to primary,
OSPF neighbors may time out.
CR 25820: TI.
Running install.bat script displays the option of 'QMCT1_RJ48'.
This is not a supported link module.
CR 25557: LB.
A problem exists in which packets bridged from FDDI to Frame Relay
are being corrupted. The router is incorrectly modifying the
Ethertype to an invalid and different value for every
bridge packet transmitted from the FDDI. The receiving router does
not understand the Ethertype so it drops these frames.
CR 25647: Frame Relay Switch.
The Status Enq. on a Frame Relay Switch circuit configured for
bi-directional polling will drift past the polling interval when
the slot is experiencing heavy traffic volume.
CR 25592: IPX.
A bus error occurs when enabling and disabling IPX globally on a
router with a large RIP and SAP table.
CR 25539: IP.
After configuring an OSPF Announce policy range, disabling the
interface will cause OSPF to change the LSDB to announce the last
address set in the range.
CR 25830: Frame Relay.
When setting wfCctOptsCngcEntry.wfCctOptsCngcCfgHwtxQThreshold to
a value greater than the value of the
wfLogicalLineEntry.wfLogicalLineCfgTxQueueLength, the following
MIB does not get set to that value:
wfCctOptsCngcEntry.wfCctOptsCngcHwtxQThreshold
CR 25822: Frame Relay Switch.
Configuring the Statistics Data Collector to run on a a switch
caused a bus error to occur.
CR 25460: SYNC.
A buffer leak may occur on a slot in which priority queuing and
BOFLs are enabled and the synchronous interface is in a down state.
CR 25480: NetBIOS.
A router configured with NetBIOS static routes may not forward
packets correctly because of a timing problem that causes a host
entry to be created with the wrong slot information.
CR 26564: DLSw.
Specific DLSw gates will incorrectly increase their memory
consumption each time you establish a session involving non-NULL
XIDs through the router.
CR 26537: DLSw.
An orphan buffer occurs when a DLS connection disconnects and
then attempts to reestablish itself. The DLS disconnection can
be caused by disabling and reenabling TCP, DLS, or physical
circuits.
CR 26748: OSPF.
An OSPF bus error occurs on routers that contain multiple
flopping OSPF point-to-point links.
CR None: IPX.
An orphan buffer error occurs as a result of encaps failure.
CR 25525: MCT1E1.
Removing the cable does not report 'Loss of Signal' in the
expected threshold.
CR 25925: Frame Relay Switch.
After resetting the slot on a Dual MCT1 and QMCT1 that contain an
external clock, the slot uses the secondary clock (internal)
rather than the primary clock (external). The slot should
use the primary clock because it is still operational.
CR 25847: MCT1E1.
When hotswapping (specifically when putting it back in) the QMCT1
in slot 2 on a BCN router while under load, the router
faults and fails to recover.
CR 25924: Frame Relay Switch.
Under certain conditions a logical line on a port with 12 logical
lines stops receiving packets and receives no interrupts.
CR 21181: SDLC.
When you disable SDLC globally, the MIB attribute wfSdlcDisable
is set to 2, but SDLC continues operating.
CR 25679: SDLC.
Disabling the SDLC base does not disconnect an SDLC session; it
remains operational.
CR 22101: OSPF.
The outcome of applying an Accept Policy filter is not used when
submitting an external route to IP.
CR 24731: Switched Services.
When the dial-on-demand inactivity timer elapsed, IP shuts down
on a WAN interface and fails to recover.
CR 25988: Frame Relay Switch.
RCN time delta value overlap will cause problems with billing
systems. The TIME DELTA for the switch RCN file is set for 24 hours
(or 8640000). Because the start time is also at midnight, there
will be a overlap or .0001 second if each file is created at
midnight and the time delta is always 24 hours (or 8640000).
CR 25960: BNX Switch.
wfDs1E1PortLoopbackState does not change when the
wfDs1E1ConfigLoopbackConfig attribute is set to lineloop(3) or
payloadloop(2).
CR None: HSSI.
This attribute determines how many seconds to wait before
transitioning to the Carrier Lost state when the Carrier Signal
is lost. When set to 0 (default), the Driver immediately
transitions to the lost state upon detecting Carrier Loss. If
the Carrier Signal returns before reaching this threshold,
the Driver fails to enter the Carrier Lost state.
