Revision Notes for Router Software 12.01/revision 1=============================================================
SITE MANAGER COMPATIBILITY
=============================================================
Router Version is managed by Site Manager version v12.01 revision 1 ------------------------> 6.01 and 6.01 rev 1
12.01 revision 1 is Year 2000 Compliance Certified by Bay Networks. It has successfully passed Bay Networks Test Procedure which tests conformance to Bay Networks Year 2000 compliance definition, both of which can be found at Bay Networks Year 2000 Web Site at http://www.baynetworks.com/year2000/. =============================================================
12.01 revision 1 corrects the following problems:
=============================================================
CR 21299: APPN.
APPN parameters wfAppnNodePortMaxRcvBtuSize,
wfAppnNodePortMaxSendBtuSize in wfAppnNodePortEntry and
wfAppnNodeLsMaxSendBtuSize in wfAppnNodeLsEntry need to be changed
from 2057 to 1500 to accommodate the 1600 MTU size of a WAN port.
CR 23552: Switched Services
If a dial on demand circuit is active in standby mode, and you
disconnect and then reconnect the BRI line, the standby circuit
connection is not properly reestablished.
CR 24390: ATM.
An MCP may occur after dynamically changing a Hybrid Mode PVC on an
ATM interface.
CR 27324: ISDN.
This is an enhancement request to allow you to configure the number
of times a router will attempt to register a SPID (for basic rate
ISDN) with an ISDN switch.
The following parameters were added to wfIsdnLocalPhoneNumEntry:
wfIsdnSpidRetries, wfIsdnSpidRetryAttempts, wfIsdnSpidRetryTimer,
and wfIsdnSpidResetBri.
CR 27745: DLSw.
When you reset an IP interface on a DLSw router, a bus error occurs.
CR 28088: IPX.
For IPX Route Filters, the log message "IPX Route Filter with rule
number 1 includes rule number 2 on circ. index 1" is generated
despite the fact that the filters are configured correctly.
CR 28250: FTP
When you transfer a file with a file name that starts with a numeric
value to the router, the router faults and receives orphan buffers.
CR 28589: BootP.
If you configure DHCP on a multinetted interface, the last IP
address configured should become the DHCP gateway. If you reboot the
router, the last configured IP address is no longer the DHCP
gateway. Instead, another IP address on that interface becomes the
gateway.
CR 29517: IPX.
If a router receives an IPX SAP packet on an interface with a
network number that is different from the one for which the packet
is destined, the packet is not dropped.
CR 29813: ARP.
Routers fail to update the ARP table according to specifications in
RFC 826.
CR 30380: ATM.
An MCP error occurs when you disable and enable ATM
signaling entities.
CR 30440: ISDN.
After you reset an ISDN BRI interface using the Technician
Interface, SPIDs get rejected.
CR 30591: DLSw.
There is no mechanism to display and monitor DLS and LLC2
connections on a per slot and per interface basis.
The following four MIB attributes were added: wfDlsSlotCurrentSessions - displays the number of DLS connections on
the slot that are in a CONNECTED state.
wfDlsSlotHiWaterSessions - displays the maximum value reached by
wfDlsSLotCurrentSessions since DLS was enabled, or since
wfDlsSlotHiWaterReset was set to 2.
wfLlcInterfaceCurrentLinks - displays the number of links on the LLC
interface.
wfLlcInterfaceHiWaterLinks - displays the maximum value reached by
wfLlcInterfaceCurrentLinks since the LLC base was enabled, or since
wfLlcInterfaceHiWaterReset was set to 2.
CR 30870: ISDN.
When you change a valid ISDN local telephone number in dynamic mode,
the router terminates operation.
CR 30998: DLS.
If you substitute a wildcard as part of a MIB instance ID when
performing a MIB Get operation on the MIB entry
wfDlsConnectionEntry, the router responds with an incorrect answer.
CR 31797: ARP.
This is an enhancement request to add a Technician Interface command
that would clear out every ARP entry learned from a specific IP
interface. A new command, clear ip arp prefix/prefix_length, was
added to clear the entries learned on the given subnet.
CR 31861: Compression.
When you run sync passthru over MLPPP with compression, and WCP is
configured on the PPP interface, several bus errors and tag
violations occur.
CR 32070: Dial-on-Demand.
In a configuration where AURP runs over a Dial-On-Demand line with
WCP configured, IP eventually loses connectivity.
CR 32142: IP.
A counter problem causes wfIpInterfaceCacheNetworks to show a larger
value than wfIpInterfaceFwdCacheSize. wfIpInterfaceCacheNetworks
should never be larger than wfIpInterfaceFwdCacheSize.
CR 32169: Spanning Tree.
The spanning tree algorithm selects the wrong bridge as the root
bridge if the difference between two bridge IDs is greater than
0x8001.
CR 32236: Technician Interface.
If you try to save a large configuration file in dynamic mode,
the router may have an error which prevents you from saving the file
from either Site Manager or the Technician Interface.
CR 33424: BootP.
If there is not enough space in the vendor field of a BootP packet,
the following message is logged:
2: 09/12/97 14:03:03.410 DEBUG SLOT 2 BOOTP Code: 8
Received request on interface 68.224.252.224, inserting subnet mask
Not enough space in vendor field to insert subnet mask
CR 32629: DLSw.
This is an enhancement request to support Remote Data Link
Correlator. Added wfDlsConnectionEntry.wfDlsConnectionRemoteDLCorr,
which contains the Data Link Correlator.
CR 32752: FTP.
During an FTP session, if you interrupt a command by entering
Ctrl-C, an orphaned buffer fault may occur and the ftp session
terminates.
CR 32779: QLLC.
After you reset the LLC base in a DLS/QLLC environment, you cannot
reestablish a session between a PC3270 client and token ring host.
CR 32840: IPX.
In network configurations where a remote router uses Group Mode
frame relay to connect to two different routers, network costing may
be set so that one of the local routers connected to the remote
routers Group Mode frame relay will not have an IPX host entry for
the remote router. This causes all IPX pings from the remote router
to fail. It also causes IPX pings to the remote frame
relay interface to fail.
CR 32879: IP.
When you try to configure additional interfaces on a BLN configured
for Host Only Mode, faults occur in map_rem.c.
CR 32902: Frame Relay.
The show fr stat circ command displays Drops as Discards and
Discards as Drops. The command does display the correct numbers.
CR 33039: DVMRP.
If a neighbor does not send a probe to DUT after the timer is
modified, the neighbor does not get timed out as per the new
modified timer value (wfDvmrpBaseNeighborTimeout). The neighbor gets
timed out with the old timer value. If DUT receives a probe after
the timer is modified, the neighbor gets timed out as per the new
timer value.
CR 33136: FDDI.
FDDI interface does not recover after receiving PC trace message
with external bypass switch.
CR 33353: Frame Relay.
Source route bridging will stop forwarding packets when you
dynamically change hybrid mode on a frame relay permanent virtual
circuit (PVC). To correct the condition, you must reset the sync
interface.
CR 33408: IP.
This is an enhancement request to add a global parameter that causes
the router to disregard packets sent to an address that the local
router knows is a broadcast address. Added a new attribute to IP
Base MIB called wfIpBaseDirectedBcastEnable which should be set to
disabled to turn off directed broadcasts.
CR 33453: LAPB.
LAPB retransmits already acknowledged X.25 packets, causing
the X25 switch on the other side to reset the LAPB session between
the X.25 switch and the router. This causes X.25 virtual circuits to
be reset and IP circuits over those virtual circuits to come down.
CR 33566: ISDN PRI.
When log messages are written to the log, an exception vector 3 -
address error may occur because of a corrupted stack.
CR 33577: IP.
A condition exists in all revisions of code where IP_BARP will
consume all buffers on a slot if an external device is trying to
reach nonexistent but valid host addresses on a subnet.
A new MIB attribute, wfIpBaseArpBufLimitPrcnt, was added to wfIpBase
to specify the percentage of total buffers that can be used by
IP_BARP for buffer saving. To monitor this buffer activity, a new IP
command, ip arp_buf was added.
CR 33604: IP.
The router stops forwarding ASB packets out an interface after you
make a dynamic change to an interface that has the same natural IP
network configured as that interface.
CR 33634: IP.
The hog buf in the IP Routing Table Manager can cause the
slot to run out of buffers, thereby causing other gates to
error on the same slot.
CR 33696: FRAD.
When you configure DLSw in dynamic configuration mode,
changing the secondary (HostFRAD) point-to-point or
multidrop local device to primary causes all sessions on the
port to fail.
CR 34023: DLSw.
When a frame relay link breaks or the FEP fails, the router
continues to poll the controller. This prevents the customer
from configuring another FEP to call the IPLS.
CR 34159: IP.
A router faults with a "watchdog restart" when it receives an IP
frame that contains a TTL set to 1,IP options of 00 (no options),
and three bytes of padding to terminate the IP header.
CR 34226: IP.
When you enable the IP Extended Filter Support parameter
(wfIpBase.20.0), filters that forward to the next-hop address do
not work correctly, resulting in an error.
CR 34254: DLSw.
The log message for a negative CAPx message shows an offset of 0 for
certain CAPx errors.
CR 34258: IP.
This is an enhancement request provide the ability to display the
total number of IP routes per slot for all slots. Use the command
"ip routes -O -s#" (where # is the slot number). If you do not enter
a slot number, all slots are displayed.
CR 34264: DLSw.
In an environment using DLSw 1795 with SDLC PU type 2.0 attached
devices, when one router sends a flow control reset to another
router, the second router still sends one more frame. The first
router receives the packet and issues a Halt-DL.
CR 34272: Technician Interface.
This is an enhancement request to increase the severity level of the
message "tf_validate: header size invalid, Object.1.18.3.5.1.4.3.1,
Instance 29.1.1" to WARNING to indicate that the filter no longer
operates correctly.
CR 34298: Technician Interface.
If you telnet to a circuitless IP address on an ARE and run various
Technician Interface processes, VBM errors may occur.
CR 34322: TCP.
TCP retransmit-time-out value (RTO) is set to wfTcpRtoMax regardless
of actual RTT (even if the actual RTT is short). If wfTcpRtoMax is
the default (4 minutes), traffic over TCP (for example, DLS)
suddenly stops for 4 minutes.
CR 34416: PPP/Multilink.
This is an enhancement request to change the fragmentation algorithm
to require that frames larger than the configured fragment size be
fragmented.
CR 34423: X.25.
When a router recovers from congestion, it sends an X.25 RNR packet,
but may fail to generate an X.25 RR packet because it is waiting for
another part of a fragmented packet.
CR 34471: DLSw.
Performing MIB GETS on wfLlcLinkEntry does not show all instances.
For example, if you configure DLSw on 2 slots, bring up DLSw
connections on both slots, and then enter g wfLlcLinkEntry.3, only
one circuit is displayed.
CR 34602: DLSw.
A bus error may occur after you delete an X.25 circuit on a client
router while two QLLC sessions are active. The bus error also
terminates operation of the second circuit on the slot.
CR 34653: DLSw.
A bus error occurs when you boot a BLN router with a variety
of DLS configurations.
CR 34660: DLSw.
If you have DLS peers pointing to each other, and one is of type UDP
or UNKNOWN and the other is RFC1795 or RFC1434, the router with the
higher revision will fail to back down to the RFC1795 router.
CR 34678: DLSw.
When a router receives an SSP Netbios_NQ_ex, it logs it as a
CANREACH_ex.
CR 34682: LLC.
LLC2 traffic filter configuration does not work properly when you
define a specific range for DSAP or SSAP values. The fact that a RIF
field is present is not taken into account when applying the filter
to the packet.
CR 34684: APPN.
APPN over LANE does not work.When a router sends a test poll to a
second router, the second router does not recognize the destination
MAC address and does not forward the packet to APPN. The MAC
override should not just change the ESI portion of the NSAP address,
but should also change the actual hardware MAC address.
CR 34719: IP.
IP will not install BGP routes when the BGP NEXT_HOP has an
unnumbered link as its next hop.
CR 34730: SNMP.
The WFTRAPS.asn file shipped with Site Manager needs to be up-to-
date with the current image version and the traps it supports.
Currently, some of the events are missing.
CR 34738: DLSw.
When you disable DLSw on a router, SDLC Link Stations remain up and
continue to poll indefinitely.
CR 34740: Token Ring.
This is an enhancement request to increase the severity of following
log message from DEBUG to either INFO or WARNING.
# 188: 07/10/97 05:06:05.292 DEBUG SLOT 3 TOKEN_RING Code: 26
Connector MAU2 open error, phase=3 error=8.
This message indicates that a serious event has occurred - one that
may prevent access to a token ring to a router. The Phase and error
codes tell you what is halting the access.
CR 34746: QLLC.
A bus error occurs after X.25 calls are cleared several times.
CR 34753: ANH.
After you boot an ANH router using ti.cfg, all partition and link
LEDs remain on, even though the router does not have an ethernet
interface configured. The lights do not go out until you run
install and select ethernet as the driver type.
CR 34776: ATM.
An orphan buffer FAULT may occur in an environment where the ATM
switch is frequently closing active ATM data virtual circuits.
CR 34868: Translation Bridge.
When a source routing traffic filter is applied to a packet, the
router drops the packet destined for the source routing interfaces,
but does not drop the packet destined for learning bridge
interfaces.
CR 34908: DECnet.
After you enable a DECnet router on an ethernet VLAN, a VBM error
occurs on a router that is attached to the ethernet VLAN via ATM.
CR 34922: PPP.
After you enable wfPppLineEntry.wfPppLineRfc1661Compliance, the
value for wfIpIntfStatsEntry.wfIpIntfStatsMaxInfo does not change.
This results in wfIpIntfStatsEntry.wfIpIntfStatsMaxInfo having a
larger value than wfPppLineEntry.wfPppLineMru. To change the value
for wfIpIntfStatsEntry.wfIpIntfStatsMaxInfo, you must either reboot
the router or reset the slot. This fix applies to only non-dial
services lines.
CR 34948: DLSw.
The log message "SSP rcv command in TCP local, 14" should be changed
to "NetBIOS DATAFRAME Rcv" to be more intuitive to the users reading
the log.
CR 34959: DLSw
Remote DLS clients do not reestablish a connection to the host
after a network disruption.
CR 34988: OSPF.
Bouncing OSPF on an Area Border Router with several point-to-point
OSPF nbrs may result in a bus error in OSPF.
CR 35041: IP.
In BayRS Version 12.00 or greater, ASB (all subnet broadcast) does
not work in ISP mode.
CR 35116: IPEX.
IPEX in gateway mode will not accept new TCP connection
requests for sessions where its TCP peer detected a TCP
Open timeout (that is, the router was too slow to accept the request
to open.) IPEX must be able to recover from unaccepted TCP Accepts.
CR 35129: X.25 Gateway.
If you bring down a large number of sessions by killing the server
process, a bus error occurs in the X.25 gateway.
CR 35132: DLSw.
After a router receives an LLC XID frame, the router may not
transmit a CANUREACH_cs message, which causes the router connections
not to come up.
CR 35136: MIB.
When you issue the "l -i wfMod" command, a bus error occurs.
Occasionally, this bus error triggers a GAME restart.
CR 35143: DLSw.
If a NetBIOS client attempts to connect to an Ethernet LANE server
or a Token Ring LANE server, the router terminates operation.
CR 35177: DLSw.
BayRS is not fully compliant with RFC 1434 or RFC 1795 when
operating with two half-duplex TCP connections.
CR 35204: DLSw.
A bus error may occur in TCP when IP is bounced on a DLSw router.
CR 35268: DLSw.
When the router receives a multicast SSP NETBIOS_NQ_ex, the ARE
experiences several errors, including an exception vector 5 - VBM
error.
CR 35328: ARE.
When you use IP traffic filters in ISP mode with the action set to
Accept, a bus error occurs if the filter is on an ATM ARE board.
CR 35361: IP.
A bus error may occur when you delete an access policy in BCC if it
was also created in BCC.
CR 35414: IP.
In a multiline setup with three or more lines, if one of the lines
goes down, the router may fail to resolve the far-end host address
via ARP.
CR 35428: DLSw.
When you run NetBIOS over DLSw Version 2.0, a panic may occur in
dls_utils.c as a result of a race condition when establishing
connections.
CR 35447: IP.
The router intermittently returns a "Fragmentation Needed but DF set
- ICMP Destination Unreachable" message with an incorrect Next-Hop
MTU at the end of the ICMP header (low-order 16 bits).
CR 35494: APPN.
When you transfer an APPN topology from one router to another, the
topology may not transfer completely.
CR 35502: APPN.
When you activate an APPN link station, a fault occurs because a
buffer is freed incorrectly.
CR 35507: PPP.
If you have two routers connected via leased line and PPP using
CHAP, and the CHAP timer is set to 0 on one router and to 60 on the
other, the router with the timer set to 0 (the receiver) leaks
memory. Eventually, that router runs out of memory and restarts.
CR 35523: ISDN.
A bus error occurs in a server one charge call ID configuration when
the router (callback server) is going to set up the call.
CR 35525: DLSw.
If you boot a router that has DLS Protocol Priority globally enabled
and there is an ARE in the router, an exception vector-2 MCP may
occur.
CR 35568: Switched Services.
When you use a dial on demand asynchronous circuit, you can only
establish a connection two times. The third time you try to connect,
you cannot ping across the dial on demand line.
CR 35571: DLSw.
A router cannot establish a DLSw session if that router
has two peers that are terminated on an FDDI port.
CR 35611: BGP.
A VBM error may occur if BGP adds a new route while running on an
ARE.
CR 35649: DVMRP.
35650: This is an enhancement request to add a log message indicating that
the state of a DVMRP circuit has changed.
CR 35675: IPEX.
When you run a large number of IPEX sessions, some sessions stop
passing data after several hours (10 to 15). The more hours it
is running, the more sessions that stop passing data. The log shows
no messages other than clock updates. Statistics show that all X.25,
IPEX, and TCP sessions are still in active states.
CR 35685: IP.
When you use a regular expression (for example, ^((123 | 1247 | 2447
| 5432))+ &) in either BGP policy or ip bgp_routes -R, IP returns
more matches than expected because the regular expression code
incorrectly expands the |.
CR 35721: IPEX.
If the IPEX tcp_accept call fails, the IPEX session is not cleaned
up. This causes IPEX sessions to remain in the TCPUP state.
CR 35798: BGP.
If you have multiple BGP connections to the same router and the "BGP
Collision Detect" parameter is set to "Disable," the router drops
one of the connections and logs a message stating that the
connection was dropped because one exists.
CR 35878: DLSw.
DLSw interoperability fails with Cisco 11.3 and IBM routers running
RFC 2166.
CR 35887: OSPF.
When you use an OSPF Announce Policy filter to aggregate a range of
external networks, the aggregated LSA may constantly refresh if a
network within the range is unstable.
CR 35893: IP.
A router configured in ISP mode experiences a bus error within a few
minutes following a reboot operation. This happens before BGP
imports the full routing table.
CR 35911: OSPF.
An AS External Route may fail to be installed into a routing table
if a more specific route with the same address exists. For example,
10.4.0.0/255.252.0.0 would fail to install if 10.4.0.0/255.255.255.0
existed.
CR 35935: DLSw.
When you disconnect a token ring interface, a memory leak occurs and
the router slot faults.
CR 35992: ARE.
When an LE_ARP request is sent to an ARE, and the request is
for the Group LAN ID of the source route bridges in the network, the
ARE fails to respond. Note: The router will now respond
to the LE_ARP, however, the network should be designed so that only
one Bay Networks router will receive and respond to the LE_ARP that
is sent.
CR 36052: OSPF.
A problem exists in OSPF where under certain configurations, it will
summarize a summary advertisement that is based on a stub network
that is down. When the stub network goes down, OSPF fails to flush
the summary generated based on the stub.
CR 71080: IP.
IP traffic filter sends a message to the router log even if there is
a match on another traffic filter higher in the list.
CR 71085: OSPF.
In an Autonomous System Border Router (ASBR), when we create a new
IP interface, it is immediately advertised as a type 5 external by
OSPF. Later, when OSPF is configured on that interface, it
now becomes a type 1 or 2 and is advertised as such. However, OSPF
does not flush out the old type 5 that was generated.
CR 71443: IPX.
A problem occurs in 12.00 in which the router experiences a bus
error when a host sends a RIP request or SAP request using a source
socket of 9001 (NLSP).
CR 71475: ISDN.
For an ISDN leased line media type, the inter-frame fill pattern
should be 7E instead of FF.
CR 71634: IPEX.
When IPEX in Gateway Mode is operational, the router exceeds buffer
space when many TCP sessions are torn down because the TCP server is
disabled. When you restart the server, the IPEX/TCP sessions do not
re-establish.
CR 71703: IPEX.
When you request IPEX configured in Gateway Mode to bring up many
TCP sessions, the router takes too long to process all the TCP open
requests, causing the peer to timeout some of the open requests.
CR 71738: IP.
A configuration with multiple BGP regular expressions may cause the
log to be filled with "Truncating regular expression" warning
messages. However, the processing of the regular expression was not
affected.
CR 71739: IP.
The ip bgp_routes -N command may display routes that are not really
being announced.
CR 71767: AppleTalk.
A problem occurs in AppleTalk in which an ARE interface can
experience VBM errors. This problem can occur in an
environment in which there is a variety of extended networks and
non-extended networks.
CR 71779: IPX.
IPX route filters fail to work properly if you configure multiple
filters on a circuit, each with a different priority. In this case,
only the first filter (first one created and highest priority) is
matched.
CR 72074: X.25.
If X.25 receives a disconnect request from the local interface and
then receives a disconnect from the remote interface through IPEX,
the VC may remain in an operational state and never be cleared.
CR 72526: IPEX.
IPEX in gateway mode incorrectly accepts new TCP connection requests
before the previous session was completely terminated, causing the
IPEX session to hang.
