=================================================== Revision 11.02/5 corrects the following problems: ==================================================== CR 32544: LLC2. When you dynamically add DLS or APPN to an IP interface, LLC2 may fail to come up. CR 33165: Frame Relay. Frame relay fails to identify an empty list of Full status inquiry and fails to close the permanent virtual circuit (PVC). CR 33235: Frame Relay. A configuration that contains many Direct Mode PVCs may Watchdog when you convert to a higher version of router code. CR 33853: DLSw. DLSw fails when the wfDlsConnectionEntry MIB entries are aged out in dls_mib.c. CR 33880: DLSw. DLSw does not use the "Backup Peer Hold Down Timer" after a TCP connection reset, only after the DLSw keepalives are exhausted. CR 33298: DVMRP. When DVMRP route switch timer expires, a delete cache message is sent to delete the old incoming vif cache entries. This delete cache message was not propagated to remote slots, resulting in upstream neighbor being pruned for certain (s, g) pairs. CR 34027: DVMRP. DVMRP routes are not declared unreachable when the reporting neighbor times out. DVMRP waits for the route expiration timer to expire before updating those routes. CR 34103: DVMRP. Router does not always prune (s, g) caches for which there is neither a local member nor a downstream neighbor. CR 34104: OSPF. A condition exists in OSPF in which an ARP request can be generated out of the wrong interface when the OSPF nexthop for that network is in transition. A response from a device running proxy ARP at that time causes installation of the host route, which results in traffic being forwarded out the wrong interface. CR 34207: DVMRP When the router learns a new and better route to source net S from vif2, it still keeps cache entries for source S on vif1 instead of switching to vif2. CR 34210: DVMRP When DVMRP triggered update is sent out due to some topology changes detected by DVMRP, the software only sends updates to the first of all the DVMRP interfaces on a given slot. CR 33696: FRAD. When configuring 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 32310: SDLC. An enhancement request to upgrade the severity level on several trap SDLC messages from Info to Warning. CR 26560: FRAD. An endless XID loop occurs when you configure the following scenario: host(3172) - ethernet - frad - frame relay (ban or bnn) - frad - sdlc - 3174(pu2.1) CR 27260: IP. When you enable the IP host cache after the router has learned a large number of hosts through the port, the router experiences a fault, causing the slot to reset. CR 28807: FTP Dynamically enabling FTP in the router does not work. CR 30336: X.25 A problem exists whereby Parallel PDN and IPEX services do not work on the same X25 line. The PDN service will call a remote X121 address of 0000000, instead of its configured remote X121 address. CR 30952: DLSw.
The DLS slot memory statistics show fictitious memory usage
by this DLS slot. This condition reflects incorrect statistics
and inhibits the establishment of new connections as the
erroneous statistic is used to determine if DLS may acquire
more memory from the system heap during connection
establishment.
CR 32880: IP. A BLN router configured for host-only mode fails during the first telnet attempt after each boot or reboot attempt. CR 32886: DLSw. If you disconnect and reconnect a PU1 controller to the SDLC primary line on a router, the DLSw gets stuck cycling between disconnected and established states. CR 32943: XB. You cannot reestablish a session between PC3270 and the IBM Host after bouncing source route base in a translational bridge environment. CR 32978: DLSw. If you dynamically delete a circuit on which DLS is configured, a Vector 2 - bus error occurs. CR 33035: OSPF. A problem exists in certain configurations where the OSPF Multihop ECMP functionality fails to distribute networks across equal cost OSPF point-to-point paths. CR 33120: SWSERV. A problem exists in Router Software Version 11.01 and later in which the router sends ISDN call setups requesting the same B channel on a PRI for successive calls. CR 33348: SWSERV. If you schedule TOD parameters for a demand circuit using NOT_AVAILABLE, after the end time has passed, the demand circuit does not become active. This is not a problem if the whole day is NOT_AVAILABLE; only when part of the day is NOT_AVAILABLE. CR 33404: APPN. A router running version 11.00 rev 6 fails with a tag violation. CR 33634: IP. The hog buf in ip_rtm_update (gate id 0x00152) can cause the slot to run out of buffers, thereby causing other gates to ERROR on the same slot. CR 33685: OSI. With load balancing disabled, OSI may install multiple MIB instances for the same route. CR 33711: DLSw. If you disable TCP on a router with 500 or more DLS connections, some of the connections never become disabled. The router will continually transmit Ras or RNRs to the local station, which may prevent the host from realizing that the connection has gone down. CR 33764: APPN. When a router is connected to an existing router (running version 11.00/4), a problem arises if you reboot the new router. The CP-CP session forms correctly, but the transfer of the APPN topology database is erratic. It can take two days for the transfer to complete. CR 33910: SYSL A problem exists when a syslog message is delivered as a UDP packet over a frame relay network with WCP enabled. When WCP compresses this packet, it sets a -1 to the next pointer of a buffer, which causes the system to fail. CR 33933: APPN. When an EN (AS/400) router is configured with multiple CP-CP sessions, the router that receives a Cross_Domain_Initiate GDS variable as a part of EN's LOCATE message incurs a tag violation error. This problem results in memory corruption while attempting to allocate and free buffers in Session Services. CR 33957: SCRIPTS. When setting up an ASN router with a MCEI interface, the configuration script fails to ask you to specify the type of WAN protocol to be used. After you configure the physical level, the process jumps to the IP configuration. CR 33995: IPX. Creating a circuit in an IPX router and then deleting that same circuit using the IPX script, causes the MIB variable wfCircuitNameEntry to be non-contiguous. The ipx.bat batch file incorrectly indexes circuits if there are circuits missing from the wfCircuitNameEntry. CR 34000: FireWall. A problem exists in FireWall in which there is no device, such as a slot mask, to control which slot FireWall runs on. If FireWall is not running on the slot that is configured with the IP address used to communicate with the management station, communication will fail. CR 34161: LLC. Deleting an interface configured with LLC2 causes the router to experience a bus error. 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 wfDisConnectionEntry (Version 11.01or later), the router responds with an incorrect answer. CR 31364: BGP. Community-based policies match routes without any community attribute. CR 32236: Technician Interface. If you try to save a large configuration file in dynamic mode, the router fails, preventing you from saving the file from either Site Manager or Technician Interface. CR 33674: QLLC. After you disable the MIB object, the state value does not change. CR 34024: BOT. An enhancement request to enable the BayRS Bisync protocol to support more leading SYNC characters. Currently, the BISYNC code is hardcoded for 2 leading SYNC characters. The customer's Bisync controller requires 7 SYNC characters. The BayRS code requires configurable leading SYNC characters in order to interoperate. CR 24909: FLASH. Routers fail to boot with Hitachi Maxell type flash cards. CR 30140: BGP. When you configure a second BGP peer between two routers, and the MIB object is enabled (default), the router terminates the second peer without logging a message explaining why the peer was terminated. CR 31607: IP. Magic route images fail in BayRS Version 11.02 CR 31938: BGP. There is a problem with the bgp.bat script (Version 1.20) when you use the show bgp policy announce/accept command to view BGP policies. If you insert more than a few entries in certain attributes, the router generates an error. CR 32204: IP. When you configure IPEX with X.25 gateway mappings, the system test requires you to disconnect the IP physical interface, then reconnect it and reestablish the TCP connections. But if you disconnect the Ethernet transceiver on the DSDE interface, you create a fault in IP that causes the MIB mappings to restart in IPEX. CR 32417: BGP. A problem exists during convergence in an AS such that BGP can submit a route with the Next Hop not on a directly connected network. Then IP installs a host entry for this Next Hop, which leads to various forwarding problems. CR 32700: BGP. When you bounce peers on a router configured for BGP, free memory decreases rapidly. CR 32980: SM. File Manager misinterprets file date stamps beyond the year 1999. CR 33056: IPX. If you have multiple route filters with the same priority, the oldest filter takes precedence, thereby ignoring the ordering sequence in the route filter table. CR 33505: DLSw. A problem occurs in DLSw that causes certain XID exchanges to fail. CR 33666: DLSw. A problem exists where reserved capx with values in the range 0x8c - 0xcf returns error messages. These values should be ignored. CR 33785: DLS. When you globally disable DLS, the MIB object still shows active connections. CR 33878: Technician Interface. If you use install.bat to install a new router using SMDS outside the US, the install.bat script adds a prefix of C1 for the configured individual address and E1 for the group address. CR 34107: Router A problem exists in BayRS 11.02/2 in which the router can experience a bus error if it receives excessive LAPB resets. This occurs particularly when the interface is attempting to activate. CR 34112: DLSw. A problem exists when non-BayRS routers send frames with different circuit ID values to a receiving BayRS router. CR 31943/ 31944: BGP. An enhancement request to "show bgp routes" to allow you to see community information being announce/accepted. CR 23861: IP. An enhancement request to allow configuration of IP Policy filters(Announce/Accept) over unnumbered links, for when certain IP routes need to be manipulated. CR 30266: Frame Relay. A bus error can occur in frame relay if a router receives frames destined for a frame relay source route interface while that interface is still initializing. CR 34388: IP. If you configure a multiline circuit on multiple slots, and you reset one of these slots, the non-multiline slots might fail to install the adjacent host for the multiline circuit. CR 28911: SM-CONFIG You cannot schedule a boot operation for the router for the year 2000 or after. CR 31649: PING-MIB The reported IP ping round-trip times are incorrect. This affects both the TI ping command and the ping MIB. CR 32394: Technician Interface. If you use the embedded enable/disable sync command from the Technician Interface, and reference a circuit by name, a bus error may occur. CR 33316: TR-LANE. When you configure a router for source route bridge over token ring LANE, it may LE-ARP for a Route Descriptor field instead of a MAC address. CR 34085: QLLC. A bus error occurs if you make multiple dynamic changes to a QLLC map entry. CR 31550: IP. The router experiences a fault when attempting to test pool priority/dial backup lines, and multiple circuits configured on one line. 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 32629: DLSw. An enhancement request to allow the deletion of a single DLS connection via the Remote Data Link Correlator. CR 33356: FDDI. In a Dual Homed configuration, PHY_A disconnects if a process runs too long in the CPU. The router reports a PHY_A disconnect and then 50 seconds later will put PHY_A back into standby. This could be a serious problem if PHY_B fails during those 50 seconds that PHY_A is disconnected. CR 33654: DVMRP. A problem exists in DVMRP where DVMRP_BASE will slowly grab buffers and not release them. This continues until the slot runs out of buffers, and the router fails. CR 33929: DVMRP. A problem exists whereby DVMRP fails to poison and respond to a route, for which it is dependent upon the sourcing upstream neighbor. CR 34358: SM-ADMIN. Technician Interface allows the user to set invalid years with the date command. Only the years 1971 to 2070 are allowed. CR 34395: OSPF. If you bounce an Autonomous System Border Router (ASBR) in an OSPF area, the Area Border Router (ABR) might permanently age out the Type 4 link for that ABR, eliminating connectivity to that ASB's external routes for all routers outside of that area. CR 34422: DVMRP. Sometimes grafts received from down stream neighbors are not propagated to upstream neighbors. CR 34456: Frame Relay. A fault may occur when you reboot a router with a configuration that was saved after certain dynamic configuration changes were made to frame relay. CR 34594: DVMRP. A router generates an error in dvmrp_timers.c at line 197s after its DVMRP neighbor times out. CR 33253: LLC. A memory leak occurs if you continually bounce a MIB object. CR 33378: DVMRP. IP fragmentation fails for subsequent multicast packets after properly fragmenting the first packet. CR 33889: RIP2. In RIP2, when a router fails to install a natural network in the routing table that it had learned as a subnetted network of that natural network. CR 34175: ATM. When you dynamically configure a router in Ethernet LANE while adding IP/RIP to the second service record, an Exception Vector2 - MCP error occurs. CR 32859: DVMRP. Certain MIB object counters do not increment properly as the router accepts multicast traffic for forwarding. See CR 32860. CR 32860: DVMRP. Certain MIB object counters do not increment properly as the router transmits multicast traffic. See CR 32859. CR 33612: DVMRP. The router fails to send in a graft after a dependent downstream router on a pruned branch restarts. CR 34374: Firewall. A problem exists in certain multiple layer 2 and 3 protocols such that when packets are received in a list of buffers rather than one buffer at a time, IP and IPX do not work together. Further, if the first packet is a non-IP packet, the entire list might bypass the filter and allow all traffic to get in. CR 34484: PPP. IP incorrectly considers the Maximum-Receive-Unit to include not only the Payload (information field), but the header as well. This can cause a discrepancy in the total packet size crossing the PPP line and the maximum protocol size. CR 34336: DVMRP. The router fails to delete mask entries from routes_by_mask_utbl in the base environment. CR 32983: LOADER. If there are two or more advance routing engines (ARE) configured in one router, and you perform a named boot without using the bn.exe image or config, one of the ARE’s will fail to load all of its executable files. CR 30380: ATM. An MCP error occurs when disabling and enabling ATM signalling entities. CR 33672: SYNC. If a port on an octal sync card receives an excessive amount of errors, resource errors occur on the other ports that are on the same chip. CR 34653: DLSw. A bus error occurs when booting a BLN router with a variety of DLS configurations. CR 34693: ATM. An error occurs when running ATM with LAN Emulation configured. CR 30591: DLSw. An enhancement request to display the number of DLS circuits active on a slot or an LLC2 interface. Without this facility, it is difficult to monitor and plan for DLSw growth on a router. CR 32822: Spanning Tree. An enhancement request to increase the severity of a debug message to the warning message "Port record not available for port X CR 34749: DLSw. A bus error occurs when you delete the DLSw slot entry and then globally disable DLSw. CR 34226: IP. When you enable the IP Extended Filter Support parameter (wfIpBase.20.0), filters that forward to next hop address do not work correctly, resulting in an error. CR 34893: ATM. An error occurs in 11.02 rev 3 and later, resulting in an Inter-Cell Gap that exceeds the configured Peak Cell Rate for a DS3 board. CR 34632: BNX Switch. If you disable the Frame Relay side of a Frame Relay/ATM interworking circuit (on the FRE), while running BNX code 7.10 rev2 when the is disabled (on the FRE) TX ATMizer status errors occur on the ARE slot. ========================================================================- Revision 11.02/4 corrects the following problems: ============================================================================= CR 33928: OSPF.
A router configured for OSPF may fail to properly advertise a Type
2 LSA for a network on which it is the designated router. This
results in a loss of connectivity to that network throughout the
AS and routers not using that network in their shortest path first
calculations.
CR 33984: OSPF.
A condition exists in OSPF (version 9.0 and later) in which an
ABR fails to originate a more specific summary net for a
non-backbone area when a less specific summary net is present in
the non-backbone area. The ABR fails to consider the validity of
the less specific summary net or whether it is even present in the
Backbone LSDB.
CR 34155: OSPF.
An enhancement request to add gate statistic reporting capability
to OSPF. This new feature will enable you to determine how many
buffers were processed after each run of the OSPF receive gate and
how many of each kind of OSPF messages were processed during that
particular run.
CR 32886: DLSw.
After a PU1 controller is disconnected and reconnected to the
SDLC Primary line on a router, DLSw gets stuck cycling between
disconnected and established states. After entering an
established state, the AS/400 sends an XID poll, which is
transported across to the remote controller. The remote controller
responds with an XID Final, which is transported back to the
central site, received by DLSw and by the SDLC code, but never
transmitted back to the AS/400.
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 33921: SDLC.
An AN router can experience a bus error fault when you set the
SDLC line to "VARY ON" on the AS400 for the remote SDLC
controllers.
CR 34135: DLSw.
On a fully configured control unit, not all LUs become active. As
a result, you must often manually deactivate and reactivate the
high numbered LUs. This condition occurs on SDLC-attached
controllers and/or a SDLC-attached host.
CR 33959: IPEX.
An enhancement request for the calling address insertion/overwrite
feature. The alarm management system used relies on the calling
address field in the incoming call to identify the device
reporting the alarm. The X.25 devices used in this network do not
fill the calling address in their calling request packets. However,
the alarm system still works because the public X.25 network
inserts the correct calling address when it receives a call
request with this field empty.
Created a new MIB variable, wfIpexMappingXlateCallingX121. When
wfIpexInsCallingDte is enabled, the calling address is
overwritten by the value specified in
wfIpexMappingXlateCallingX121, if configured.
CR 34018: GAME.
A debug message causes confusion between fault and debug code,
resulting in stack dumps.
CR 24909: Flash.
Routers will not boot with Router Software Version 8.12/11 and
later using Hitachi Maxell type flash cards.
CR 34266: SDLC.
A DLC-SDLC DLSw connection does not recover after VC moves from an
active to inactive state.
----------------------------------------------------------------------------- Revision 11.02/3 corrects the following problems: ============================================================================= CR 31179: IPX.
High CPU utilization during IPX updates may lead to out-of-buffer
faults.
CR 32246: ATM.
Configuring AppleTalk AURP on an ATM/ARE interface causes a BN
router to fault.
CR 32284: OSPF.
A problem exists in router software versions 10.01 and later where
OSPF faults when you configure announce policies on the router to
aggregate external class C networks into class B or class A
networks.
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 29796: Unsuccessful SPID registration after a line failure. 31259: The Line Manager faults when bringing down an ISDN line. 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 32778: Frame Relay.
An problem exists in which wfSyncLackRescTx is
incrementing too frequently when Protocol Priority is enabled.
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 30313: OSPF.
MAX aged LSA’s (3600) are not being flushed from LSDB’s after
disabling one of the ABR’s in a dual ABR.
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 33025: DLSw.
After terminating a DLS connection entry between a PC3270 and
a host, the MIB variable wfDlsConnectionEntry.wfDlsConnectionCct
is set to 0.
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 30810: ASN.
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 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 29254: APPN.
APPN DLUR fails to send discovery packet to PUs. As a result,
the LLC2 session never terminates.
CR 31082: Hardware Link Module.
A problem exists in which a dual port 100BASET card is corrupting
frames installed in a BLN router. The problem occurs when sending
1504-byte frames that contain UDP data bi-directionally at wire
speeds across both ports on the Ethernet card.
CR 32008: Switched Services.
A problem exists in which dial backup fails after dynamically
creating a frame relay backup circuit using PRI ISDN. The failure
occurs when one of the backup circuits does come up properly (not
always the same one). Resetting the PRI slot alleviates
this problem.
CR 32408: X.25.
A problem exists in which multiple IP interfaces/service records of
type PDN are created on an X.25 circuit. IP statistics indicate
that the IP interfaces are sending traffic through a particular
SVC, but IP traffic is received but not transmitted.
CR 32438: OSPF.
A problem exists in the router code that prevents a Max Aged
OSPF route from aging out of the IP routing table.
CR 32587: DVMRP.
A graft is not sent toward the source when a DVMRP interface
becomes available after you reset a slot. A graft must be sent to
undo the prune that was sent (correctly) when the slot was reset.
This prevents multicast traffic from being forwarded out the
recovered slot for the duration of the prune time-to-live interval
(default 5 minutes).
CR 32753: OSPF.
A problem exist in which an area border router with area range
summaries configured can get stuck in load state while the
other side of the adjacency is in full state.
CR 29813: ARP.
Routers fail to update ARP table according to specifications in
RFC 826.
CR 30546: Firewall.
The CheckPoint Log Viewer occasionally displays incorrect time.
The date is correct, but the time may be ahead by several hours.
CR 30897: BGP.
A BGP Announce Policy that tries to aggregate a large number of
routes into a single route causes a tag violation to occur.
CR 31634: ATM.
The UNI3.1 configuration option in install.bat is malfunctioning.
CR 31942: BGP.
The script file "show BGP policy announce" fails when evaluating
BGP community information.
CR 32069: PPP.
The ASN sends PPP Protocol rejection packets despite
receiving valid packets.
CR 32238: ATM.
After restarting a router, LECs can get stuck in the BUSCONNECT
state until you bounce them manually.
CR 32240: X.25.
Call requests are always cleared if full addressing is set to OFF.
CR 32429: DLSw.
DLSw RFC mode becomes corrupted with QLLC and outbound calls.
CR 32445: BGP.
A problem exists in ISP10.00, 11.00ISP, 11.01ISP and 12.00 in which
network range entries get merged incorrectly in an IP policy gate.
This results in more specific routes being incorrectly advertised,
along with the aggregate route.
CR 32580: Spanning Tree.
The Spanning tree algorithm fails to converge predictably under
failure conditions.
CR 32712: BGP.
The bgp.bat script faults when attempting to view BGP policies
via show bgp policy announce/accept.
CR 32864: IPEX.
If a failure occurs at the remote IPEX IP interface, IPEX can no
longer establish TCP connections with the remote IPEX routers.
An enhancement to the current IPEX implementation allows you to
configure the secondary remote IP interface for backup using
the new MIB attribute wfIpexMappingRemoteBackuplp.
CR 32891: DLSw.
When the ARE receives a CUR and initiates a test poll to a host
attached to the C100 switch, data from the host back to the ARE
fails to switch over from the BUS to the Data Direct SVC.
Performance is limited by the BUS and is very poor.
CR 29666: APPN.
The router fails to send discover packets to PU on an SDLC line
when a PU is varied off by NetView.
CR 31772: GAME.
The wfKernelEntry.wfKernelAliasBuffsDropped counter increments
for both an alias gate that cannot get a copy buffer and an alias
gate that has no members. This makes troubleshooting difficult
because you cannot determine whether a router issue is
performance-related or otherwise. A new MIB counter,
wfKernelAliasNoMembers, has been added. This MIB counter
increments when a buffer is dropped when a gate alias has no
member. Therefore, wfKernelAliasBuffsDropped will increment only
when a gate cannot get a buffer.
CR 31947: Switched Services.
A fault occurs in map_rem.c line 60 in a BCN-2 router after the
frame relay circuit at the BCN-2 router is disabled and enabled
three times.
CR 32309: PPP.
A PPP link with compression can get caught in a state in which
it will storm the link between the peers with LCP protocol-reject
packets.
CR 32542: DSLw.
When a router receives data from a remote peer or from LLC2,
an attempt is made to empty the flow control queue. The log file
shows that the router received a flow control update in a IFCM
message (no associated data), which prevented the queued data from
being sent.
CR 30062: ISDN.
ISDN leased line fails to recover after incurring a line failure
on an ARN router when you configure ’Dialup 2 B + 1 D’ on the
other ISDN interface and add it to a Backup or Demand pool. This
can cause the backup circuit to remain operational indefinitely.
CR 30565: OSPF.
OSPF maintains and exchanges invalid LSDB entries (over
47,000), causing excessive memory usage.
CR 30998: DLSw.
Using a wildcard in part of a MIB instance ID no longer works when
specifying a GET request on wfDlsConnectionEntry.
CR 31240: IPX.
A problem exist in router software version 11.00 and later that
can cause the IPX encaps gate creation to fail after a synchronous
line is bounced. This prevents the transmission and reception of
non-broadcast IPX traffic on that synchronous interface.
CR 31681: DLSw.
After issuing a connect_out, DLSw should receive a positive
acknowledgment from SDLC. In some cases, after deleting and
re-adding (dynamically) a local device entry, the positive response
is never generated, leaving DLS in an indeterminate state.
CR 31938: BGP.
Numerous problems occur in bgp.bat when using "show bgp policy".
CR 32155: Source Route Bridge.
An orphan buffer occurs when changing the bridge ID to an
unsupported value using the Technician Interface.
CR 32390: TCP.
A problem exists in router software 11.00 and later in which
the MIB counter for established TCP sessions
(wfTcp.wfTcpCurrEstab.0) can become inaccurate. When TCP sessions
are lost and then reestablished, these connections are incorrectly
counted as additional connections.
CR 29305: DLSw.
IBM 4702 Branch Bank Controller fails to connect with DLS 1795.
CR 29688: OSPF.
ip ospf_lsdb -t5 shows more LSDB’s for the default route than
actually exist.
CR 30611: FTP.
When you enter the command XXXV twice from the FTP prompt,
the router faults in ftp_dsrv_xmit.c.
CR 31178: IPX.
When you ping a router configured with IPX, both the request and
the response have an incorrect value in the IPX header for packet
length. An IPX ping request, for example, is 37 bytes, yet the
value of the packet length in the IPX header has a value of 36
bytes.
CR 28325: OSPF.
Learning about an OSPF neighbor whose router ID is 0.0.0.0
causes the router to create invalid LSDB entries.
CR 28563: APPN.
The default setting for APPN port defaults to Disable. According
to the user manual, the default (and desired) setting should be
Enable.
CR 18444: Switched Services.
The capability to specify a total exclusion of a weekend/weekday/
specific day is missing. The ability to define a Scheduler entry
of weekday/weekend or specific day with the mode set to Not
Available is required. Currently, you can specify only the
available time period.
CR 33204: OSPF.
After bouncing the OSPF base record, an exception vector 2 bus
error occurs in ospf_update_sum_asb+0x168.
CR 33653: OSPF.
The TOS and metric fields in a summary link state update are
corrupted.
CR 33729: DLSw.
A VBM error occurs when you attempt to copy a buffer set up by
dls_tcp_rcv_op_act; the buffer’s end offset is invalid.
CR 33806: IPX.
A problem exists where the router stops passing IPX NetBIOS
traffic in a frame relay group mode hub and spoke environment
using NetBIOS static routes with Novell Conformance disabled.
CR 30446: ATMZ_ARE.
Traffic is shaped incorrectly with VC-Clipping enabled.
CR 33379: DLSw.
ATM Data Direct fails to establish after ATM link is disrupted.
CR 32094: ATM.
Data corruption can occur on packets larger than 1800 bytes.
CR 32296: Neptune.
The ARN U interface adapter module fails to respond to NT1 loop
codes.
CR 32843: ATMLANE.
If you Telnet into the router via the ATM (LANE) port and
disconnect abnormally (physically remove Telnet client station
off the network without disconnecting Telnet), the router fails to
terminate the Telnet process.
CR 33072: AT.
A slot synchronization fault may occur on an ARE slot when you
reset a non-ARE slot configured for AppleTalk.
CR 33155: SDLC.
An SDLC connection will be dropped when an ARN router sends a
packet before it is polled.
CR 23734: DLSw.
XID-P’s were dropped once the DLS connection has been established
and then disconnected; that is, the DLS connection was in a
disconnected state.
CR 33151: IPEX.
A problem exists between 11.00 and 11.02 implementations of IPEX
in which an 11.02 router cannot establish calls with an 11.00
router. Added a new MIB parameter, wfipxlnscallingDte, in IPEX
base. The default is disabled to prevent the calling DTE address
from being added, but will allow router software version 11.02 to
interoperate with lower revisions of code.
CR 33496: IP.
In router software 11.02 and later, IP frames received that are
destined for a local host are not cached if that host has not yet
been resolved
CR 33307: IPX.
Packets are not always forwarded out the direct route. This
problem can occur when an IPX route learned via RIP is also
a directly-connected route. If the route is learned through RIP
first, and the cost of the RIP-learned route is less than the
directly connected route, the directly-connected route is dropped.
CR 25171: DECnet.
The router experiences a bus error when DECnet is deleted in
dynamic mode on a frame relay circuit.
CR 32927: DECnet.
A router configured for DECnet IV over PPP sends out " UNKNOWN
TYPE" of DECnet packets.
CR 33136: FDDI.
An FDDI interface fails to recover after receiving a PC trace
message with external bypass switch.
CR 33156: GAME.
Running the "show bridge forward" script causes the router to fault
with a tag violation.
CR 33410: IPEX.
If the X.25 client timer expires while IPEX is waiting for
a clear confirmation from the remote X.25 connection, (end-to-end
mode only), X.25 will clear the call locally, causing the LCN to
be freed. However, all structures related to the VC do
not get cleaned up properly. As a result, any calls placed to
this LCN will fail.
CR 32885: DLSw.
When a DLS TCP passive connection receives a connect request
from a source IP address configured as a DLS backup peer,
the TCP connection is opened but that information is not made known
in the backup peer data structure. If the primary peer is
disabled, DLS attempts to open a connection with the backup peer
since it does not know the connection is already open. TCP fails
handle the request properly, resulting in a router fault.
CR 33330: Learning Bridge.
Bouncing a Learning Bridge interface results in a bus error when
you disable Learning Bridge globally. On an ARE, a Vector2 MCP
error can occur.
CR 31525: Technician Interface.
When trying to enable or disable the IPX base or an IPX circuit
using the enable/disable script, the router responds with an
error.
CR 33780: Learning Bridge.
If you globally disable Learning Bridge and then enable it on a
slot, bridging fails to come up on that slot.
CR 33609: DVMRP.
When the prune timer expires on an intermediate router, grafts are
sent for (s,g) items in the cache that had a status of pruned.
Prune may be sent with incorrect prune_timer, making the
prune_timer inconsistent with the router and the
upstream neighbor. As a result, the upstream neighbor may forward
traffic earlier than expected.
CR 32268: X.25.
A X.25/PDN configuration cannot forward IP datagrams larger than
1915 bytes.
----------------------------------------------------------------------------- Revision 11.02/2 corrects the following problems: ============================================================================= CR 32039: DLSw.
A router may fail to identify the RFC version of its remote peer,
thereby preventing it from forwarding any ICANREACH packets and
preventing DLS connections from establishing.
CR 31629: ARN.
The internal modem on an ARN router does not completely transfer
(xmodem/ymodem) files with its default settings. The modem allows
only about 20-29 percent of the file to be transferred.
CR 30535: DECnet.
DECnet unicast traffic using PDN/X.25 does not get forwarded out
the synchronous interface on AN and ASN routers.
CR 31980: IPX.
In router running software version 11.01 and later, a slot will
start aging all IPX routes in its tables, even if it doesn’t own
the route. When the route age gets to three times the update
interval of the interface on that slot, the route becomes
unreachable and is removed from this slot’s table and the route
tables of the other slots.
CR 32354: IPEX.
An interoperability issue exists between 11.01 (remote) and
11.02 (central) routers. This condition occurs only when the
central (BCN) router is booted with an 11.02 image and the remote
(AN) router is booted with a 11.01 image.
CR 32498: OSI.
The router experienced a fault when attempting to boot with
OSI and IPX.
CR 30327: DLSw.
When you terminate DLSw on a ARE slot (ATM LANE), router
performance degrades after the host’s MAC address is aged out from
the cache. After the MAC address is aged out, performance
degradation begins shortly thereafter.
CR 30919: OSI.
AN OSI adjacency will not always come up between two routers that
are connected via PPP. This problem is evident about 80% of
the time. Bouncing the interface may resolve this problem, but not
in all cases.
CR 31075: DLSw.
A problem exists in software version 11.00 in which the router may
fault when aging out the DLS test table after DLS connections have
been established. This causes the router to fault with tag
violation errors or bus errors.
CR 31297: DLSw.
The connections in the DLS LLC1 connection table are incorrect at
router1 when there is more than 1 connection to the same
destination. The error displays at router1 when both end stations
have a "connected" LLC session to the host.
CR 31449: IP.
When running a router in ISP mode, configuring a log and/or accept
traffic filter causes a bus error to occur.
CR 31510: QLLC.
When you set wfX25QllcAddrMapOptions with option 2, the AN router
locks up, requiring you to reboot to restore router operations.
The lock-up occurs after a X.25 call is placed to a AS/400 for a
downstream PU 1.0 device.
CR 31590: DLSw.
A router may fail to forward ICANREACH SSP messages to a remote
peer if that router receives XID polls before fully establishing
TCP connections.
CR 31718: ATM.
In an ATM Classical IP environment, an MCP error occurs on an
ATM slot when the AtmArpServerRegInterval timer expires. The
default for this timer is 15 minutes for an ATM client, and you
cannot change this parameter in the MIB, even though Site Manager
states otherwise.
CR 31804: GAME.
A problem exist in the ARN Ethernet motherboard that prevents you
from configuring the buffer size. This could cause a problem in
an OSPF network where a Links Advertisement exceeds 1824 bytes.
For a large link state database, the Router Links Advertisement
will fragment but will not be able to reassemble if the packet
exceeds 1824 bytes.
You can set the buffer sizes to either 1824 or 4800 bytes on
non-token ARN routers. The default is 1824. This setting will be
saved in NOVRAM and will be read in at boot time.
Buffers can be carved from the Technician Interface as follows: set wfKernCfgParamEntry.wfKernCfgParamDelete.1 1
commit
set wfKernCfgParamEntry.wfKernCfgParamBufSize.1 4800 (or 1824)
commit
set wfKernCfgParamEntry.wfKernCfgParamDelete.1 2
commit
reset 1
CR 31859: IPX.
When bouncing a ISDN BRI interface for a DOD circuit, the router
experiences a bus error when the DOD circuit is the next hop
address for an IPX static route. A bus error does not occur if
there is not an IPX static route configured for that circuit.
CR 32524: PPP.
After upgrading to router software version 11.02, PPP connectivity
problems occur because of the new defaults for the MRU size.
There are two new MIB parameters that you can set to comply with
the suggested MRU of 1500 in RFC 1661:
wfPppLineEntry.WfPppRfc1661complianc
wfSwservOptsRfc1661compliance
CR 26853: DLSw.
After disconnecting and reconnecting the SDLC lines to the PU
or to the host on an SDLC-to-SDLC connection, a recovery problem
occurred.
CR 26870: SNMP.
An enhancement request to allow you to set a threshold on the
router for the maximum amount of buffers that SNMP can allocate.
CR 27393: LB.
If you configure LB in dynamic mode and you disable LB globally,
the router experiences a bus error.
CR 28318: APPN.
Configuring HPR over a SDLC link that connects two routers
prevents DLUR/DLUS sessions from establishing.
CR 29853: BGP.
Setting up Black Hole Routing to respond with the message "ICMP
Unreachable" does not work. Instead, it responds with
the message, "Does Not Respond".
CR 29858: IP.
A VBM error occurs on the ARE when processing UDP checksum.
CR 30033: DLSw.
DLSw/SM should support MAXPDU > 2057 on SDLC links, but it does
not.
CR 30070: IP.
Nexthops to destination networks remain in route table even after
disabling circuits.
CR 30610: ARE.
Running the script "show process cpu" on an ARE while running
traffic causes watchdog panics.
CR 30853: ARE.
DLSw experiences a problem when an XID poll sequence reconnects
an APPN session.
CR 30885: BGP.
You are unable to change the local_pref of routes that have an
origin of incomplete on a BGP Accept Policy.
CR 31054: AT_Dial.
When a USR modem is attached to a quad or octal sync module, no
data gets passed. The modems call/ans and connect but do not get
passed the LCP configuration. The "Sending LCP Configuration
Request" packets are being seen, but there are no LCP
config/requests received at either router.
CR 31062: IPEX.
X25/IPEX does not pass called/calling address.
CR 31262: DLSw.
A BLN router configured with SDLC and Token Ring produces a fault,
triggering service termination and a system restart.
CR 31315: SS/BACP.
Traffic reduced but BAP secondaries remain operational. Late
BAP messages are ignored.
CR 31517: ATM LANE.
Routers running router software 11.00 or later will fault on an
ARE interface upon receipt of an IP multicast packet.
CR 31546: DLSw.
V20 to V20 unconfigured peer connections do not establish.
CR 31644: QLLC.
A PC3270 client cannot reestablish a session after rebooting.
CR 31830: DVMRP.
Configuring DVMRP on a 100BASE-T appears to fault on FRE2s,
thereby disabling AREs running DVMRP. The AREs MCP and the FRE2
faults in dvmrp_cache.c line 800 (looks like RPC failure).
CR 31856: SMDS.
Unable to forward IP datagrams to destinations via 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.
CR 31926: Translation Bridge.
Translation Bridge (XB) stops caching RIFs for no apparent reason.
Connectivity is not affected because the router still sends out
AREs.
CR 31957: AT.
A VBM CPU read midpage error can occur on a ARE routing AppleTalk.
CR 32016: NBIP.
A bus error occurs in the NetBIOS over IP code on the router after
a slot resets or after a boot.
CR 32111: OSPF.
When LSU’s are multicasted out, the router does not fill one
packet fully before sending out another packet. The same holds true
for sending out ACKS. As a result, for an update event (LSU’s plus
ACK’s) that can be completed with the exchange of 23 packets, the
router exchanges approximately 350 packets.
CR 30925: ATM.
Routers running router software 11.00 or later will fail in
address registration if you specify an ATM prefix of 45.
CR 31028: DVMRP.
A problem exists in router software 11.01 in which IP multicast
traffic may not be forwarded out of an interface on a
slot for up to 5 minutes after the slot is reset.
CR 31182: BGP.
When BGP goes down, BGP routes authored by remote slots are not
deleted.
CR 32088: ATM LANE.
An ARE configured with Token Ring LANE and IP Token Ring End
is LE-ARPing for a MAC instead of for a RIF.
CR 26324: IPX.
Version 8 IPX MIB information still present in configuration
after upgrading to version 10. This produces a configuration file
that takes up additional flash space, and produces Version 8 IPX
MIB objects that are no longer valid within the config file.
CR 30410: Source Route Bridge.
The router experiences bus errors when adding a Source Route
bridging circuit when Source Route Bridging has been globally
disabled.
CR 31710: IP.
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 32046: Source Route Bridge.
If you disable the Source Route Bridge (SRB) base when booting the
router, a bus error may occur.
CR 20225: Switched Services.
Log messages for Switched Services-- including Dial backup, BOD,
Dial on Demand-- lack sufficient information to clearly describe
the operation taking place.
CR 28170: Router Redundancy.
Enhancement request to add a new attribute (wfRRedundWarmBoot) to
the wfRRedundGroup object. This new object allows you to
dynamically change the role switch mode of the routers between
"warm boot" (method used in software version 11.00 and earlier)
and "hot swap" (method used in software version 11.01 and later).”
Please note that the "warm boot" and "hot swap" versions are
incompatible, therefore, all routers running Router Redundancy must
be running the same version.
----------------------------------------------------------------------------- Revision 11.02/1 corrects the following problems: ============================================================================= CR 30791: ATM.
Routers running router software 11.00 or later will fail to
acknowledge LE_ARP responses from the C100, causing intermittent
connectivity problems between the router and the switch.
CR 31464: Translation Bridge.
A NetBIOS session fails to establish itself after the
translation bridge base is bounced. This occurs because the
translation bridge drops the NetBIOS datagram packet sent by the
server after bouncing the translation bridge base. As a result,
the NetBIOS datagram packet never reaches the Enet (LB).
