------------------------------------------------------------------------------
Revision 10.01/12 corrects the following problem:
=============================================================================
No CR: ASN
The checksum on the ASN may become corrupted, preventing the ASN
from booting. To correct the problem, upgrade your current
asnboot.exe file to version /rev/10.01/12 and your current
asndiag.exe file to version 2.28.
------------------------------------------------------------------------------ Revision 10.01/11 corrects the following problems: ============================================================================= CR 33910: SYSLOG.
A bus error may occur when you telnet to a router on which SYSLOG
and WCP is enabled.
CR 33853: DLSw.
The router faults when the MIB object wfDlsConnectionEntry is aged
out.
CR 33922: SDLC.
An AN router may experience a bus error fault when the SDLC is set
to "VARIED OFF" on the AS400 for the remote SDLC
controllers.
CR 33711: DLSw.
When you disable TCP on a router configured with 500 or more
DLS connections, some connections remain active. The
router transmits RR's or RNR's to the local station continually,
possibly preventing the host from realizing that the connection
has gone down.
CR 33995: IPX.
The batch file ipx.bat incorrectly indexes circuits that are
missing from the wfCircuitNameEntry. When a circuit is created
and subsequently deleted, the wfCircuitNameEntry can become non-
contiguous. If you use the IPX.bat to enable or disable any of the
IPX circuits that are greater in value than the circuit
(wfCircuitNameEntry) that was deleted, an error indicating that
the IPX circuit xxx is not found or the wrong one (previous) is set.
CR 34018: GAME.
A debug message causes confusion between fault and debug code,
resulting in stack dumps.
CR 27162: IP.
The router produces a watchdog error in r_next_range.
CR 34161: LLC.
Deleting an interface configured with LLC2 causes Site Manager
to set the LLC base record to delete, which unloads LLC from the
slot, causing a bus error to occur.
CR 24909: Flash.
Routers will not boot with Router Software Version 8.12/11 and
later using Hitachi Maxell type flash cards.
CR 33957: MCTE1.
If you run install.bat on an ASN router with an MCE1 interface
and you try to configure it, you are not prompted for a WAN
protocol (for example, Frame Relay, Standard, or PPP).
CR 33798: HW_PROCESSOR.
The router periodically checks to verify that the I/O module
has not disconnected from the chassis by sending a signal to a
certain pin on the I/O module. Noise occurring on that pin at the
time of the check can cause the signal to be interpreted
incorrectly, causing the router to generate the following message:
# 816: 07/08/97 08:31:03.769 WARNING SLOT MODULE Code: 3
I/O module has been removed.
------------------------------------------------------------------------------ Revision 10.01/10 corrects the following problems: ============================================================================= CR 32246: ATM.
A problem exists in 10.01 where a VBM error is detected, causing
the BN router to fault when AppleTalk is configured on an ATM/ARE
interface configured with AURP.
CR 30810: GAME.
A PPP link over DOD fails to activate on an ASN router configured
with special hardware (32MB RAM, 1 Quad-BRI, 1 or no other
module). The ASN router shows different types of error messages
usually associated with LCP failure and or buffer
starvation.
CR 31710: GAME.
A problem exists in router software version 8.12 through 11.01/1
in which a gate that exists is being killed by other slots after
having already been killed by the original slot.
CR 33025: DLSw.
After terminating a DLS connection entry between a PC3270 and
a host, the MIB variable wfDlsConnectionConnectionCct is set to 0.
CR 32544: LLC.
When dynamically deleting and then re-adding DLS or APPN to an
interface, LLC2 will intermittently fail to come up. To activate
the LLC2 interface, you must globally bounce LLC.
CR 32778: Frame Relay.
An problem exists in 10.01 in which wfSyncLackRescTx is
incrementing too frequently when Protocol Priority is enabled.
Protocol Priority should check to see how many buffers are
available on the TX descriptor queue and then place only that
number of buffers on the descriptor ring.
CR 32927: DECnet.
DECnet may periodically send out an invalid packet instead of a
full routing update.
CR 33729: DLSw.
A router configured with DLSw over ATM Lane circuits experiences
faults.
CR 32400: OSPF.
When an intra path to an ASBoundary router changes, an ASB Summary
LSA update routine will not be called unless the intra path is the
best route.
CR 30313: OSPF.
MAX aged LSA's (3600) are not being flushed from LSDB's after
disabling (power down) one of the ABR's in a dual ABR.
------------------------------------------------------------------------------ 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 the 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
<circuit name>", 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<ENTITY>, -s<SLOT>, -f<SEVERITY>, 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
MIB objects returns. Use "list wfIpx*" to return all MIB objects
that begin with wfIpx. This command is case sensitive.
CR 27965: IPX.
29317:
28078:
IPX fails to upgrade a NetBIOS static route when the 8.12 router
software version instance ID is a length of 9. If a special
character exists in a pre-9.00 configuration, a "\" character
should be prepended to the special character. Also, if a name is
less than 16 characters, append an asterisk (".*") to the end to
account for functionality prior to router software version 9.00.
CR 23591: DLSw.
The MAC and NetBIOS cache would not age out correctly.
CR 28680: OSPF.
Internal cost is not compared when two LSAs give equal OSPF type 2
cost to the same destination.
CR 29529: OSPF.
When you attempt to bounce IP in two remote AS boundary routers, a
bus error occurs.
CR None. ARE.
An ARE fails to ping to a device attached to an IBM 8260 in
LAN emulation.
CR 28291: AT.
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
