Workaround: There is no workaround.
• CSCsj60462
Symptoms: Unicast traffic is multicasted.
Conditions: This symptom is observed if two sources send traffic at the same time.
Workaround: There is no workaround.
• CSCsj75907
Symptoms: Traffic may be lost, and the port mode VC goes down.
Conditions: This symptom is observed when an OIR is performed on the PE edge interface in an
L2VPN setup.
Workaround: Reset the interfaces on the PEs.
• CSCsj88665
Symptoms: A device with a PA-MC-2T3+ may reset because of a bus error if a channel group is
removed while the show interface command is being used from another telnet session at the same
time, and then the telnet session is cleared.
The device may also display Spurious Memory Accesses.
Conditions: These symptoms have been observed in the latest Cisco IOS 12.4T and 12.2S releases.
Workaround: Do not remove a channel group while using the show interface command for that
interface.
• CSCsk27147
Symptoms: The following SNMP is incorrectly generated:
%SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input queue full
This issue is affecting the CISCO-MEMORYPOOL-MIB instead.
Conditions: Occurs on a Cisco 2600 series router running Cisco IOS Release 12.4(11)T3. The router
keeps dropping SNMP packets. The log shows that the packets are dropped because of the input
queue being full. Although the utilization is sometimes high, this could not be the root cause, as the
router keeps dropping packets regardless of the current utilization. Also, the SNMP process takes
5 to 20 percent of the CPU load.
Workaround: Exclude ciscoMemoryPoolMIB from your query with the following commands:
snmp-server view public-view iso included
snmp-server view public-view ciscoMemoryPoolMIB excluded
Apply this view to the RW community string. This view will exclude only ciscoMemoryPoolMib,
all other MIBs will be available.
• CSCsk31502
Symptoms: A router that is running IPv6 in IP tunnelling may reload upon receiving a malformed
packet.
Conditions: The router needs to be configured for IPv6 in IP tunneling.
