Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• In releases where caveat CSCdy36604 is resolved, you cannot use SNMP to retrieve dot1dBase
group data on VLANs where the spanning tree protocol is not enabled. This problem is resolved in
Release 12.1(23)E. (CSCee39798)
• HSRP tracking might incorrectly track two instances of the same interface, stating that one instance
is down while the other is up. This situation causes the HSRP priority to be decremented by 10. This
problem is resolved in Release 12.1(23)E. (CSCed95701)
• When the Multicast Border Gateway Protocol (MBGP) table has an invalid entry for the originating
Rendezvous Point (RP), Multicast Source Discovery Protocol (MSDP) Source-Active (SA)
messages from an interior Border Gateway Protocol (iBGP) peer might not get populated because
of RPF check failures. This problem is resolved in Release 12.1(23)E. (CSCed68093)
• When an OSPF external route has a forwarding address with a next hop address in the routing table,
the next hop address does not get updated in the type 5 link-state advertisement (LSA) when the
forwarding address gets a more specific entry in the routing table with a different next hop address.
This problem is resolved in Release 12.1(23)E. (CSCed59370)
• Configuration of fair queuing fails on virtual-template interfaces. This problem is resolved in
Release 12.1(23)E. (CSCed54330)
• You might see high CPU utilization if you enter the logging synchronous command. This problem
is resolved in Release 12.1(23)E. (CSCed16920)
• If you enter the show tech-support command, you might see “%SCHED-2-NOTWATCHTIMER”
and “%SCHED-3-STILLWATCHINGT” messages. This problem is resolved in Release 12.1(23)E.
(CSCec67602)
• In a PIM dense mode environment, a forwarding interface might be pruned because join messages
are delayed. This problem is resolved in Release 12.1(23)E. (CSCec37022)
• In releases where caveat CSCdz18109 is resolved, you cannot ping or make Telnet connections to
outside local addresses from the NAT router with “ip nat outside source ...” translations configured.
This problem is resolved in Release 12.1(23)E. (CSCec33530)
• With the distribute-list command configured to filter redistributed EIGRP static routes, when you
configure the filtering to permit additional static routes, the routes are not redistributed. This
problem is resolved in Release 12.1(23)E. (CSCdz21986)
• The show interface summary command might truncate some of the final characters of an interface
name. This problem is resolved in Release 12.1(23)E. (CSCdx62060)
• If you power-cycle redundant SFMs, DFC-equipped switching modules might not come back online.
This problem is resolved in Release 12.1(23)E. (CSCin70599)
• When a Multicast Source Discovery Protocol (MSDP)-enabled rendezvous point (RP) for a
multicast group fails and an incoming (*,G) join message is received, the RP does not build an (S,G)
state from its Source-Active (SA) cache when it should do so. Depending on the topology and if a
Shortest Path Tree (SPT) threshold is configured as infinite, this situation might result in a multicast
forwarding interruption of up to 2 minutes. This problem is resolved in Release 12.1(23)E.
(CSCee89438)
• A reload might occur if the output of a show command is left at the “More” prompt for an extended
period, and you attempt to resume display of the command output. This problem is resolved in
Release 12.1(23)E. (CSCee89232)
• For ACEs that match on DSCP, 7 bits instead of 6 bits are programmed into the ACL TCAM. This
problem is resolved in Release 12.1(23)E. (CSCee39170)
• OSPF area border routers (ABRs) might continue to generate summary link-state advertisements
(LSAs) for obsolete nonbackbone intra-area routes. This problem is resolved in Release 12.1(23)E.
