Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: Apply following view:
snmp-server view Flash iso included
snmp-server view Flash ciscoFlashMIB exclude
snmp-server view Flash ciscoFlashDevice exclude
snmp-server view Flash ciscoFlashPartitions exclude
snmp-server view Flash ciscoFlashPartitionTable exclude
snmp-server view Flash ciscoFlashPartitionEntry exclude
snmp-server community <name> view Flash RW
If this is not enough to get rid of SNMP queue full, reload the router so that the view applies at the
router bootup.

Symptoms: Router crashes following a shut/no shut on the main interface.
Conditions: Occurs on a router running Cisco IOS Release 12.2SXH2a. IPv6 traffic must be flowing
over the WAN interface for multiple IPv6 prefixes. The crash occurs when a shut/no shut is done
on the main interface on which multiple subinterfaces have been configured and IPv6 routing is
enabled.
Workaround: There is no workaround.

Symptoms: When there are two PA-2T3 cards on a VIP6-80 and hard loop one port on one PA-2t3,
it causes the port on the second PA-2T3 card to flap. The impact of the issue is that the interface
flaps once and it results in dropping of 6-7 packets.
Conditions: When we do a shut/no shut on a serial port, the other serial port on the same VIP might
flap once.
Workaround: Put each PA-2T3 card on different VIP modules.
Further Problem Description: Any Cisco IOS release that incorporates CSCsj96781 will definitely
see this bug. The other affected serial port can belong to the same PA (in case of two-port T3+ PA)
or it can belong to a different PA on a different bay but on same VIP.

Symptoms: A Catalyst 6500 switch with an etherchannel spanning multiple DFC modules may drop
packets for a certain MAC on egress. This happens when one of the DFCs carrying the etherchannel
has an incorrectly programmed MAC address entry, pointing at the internal drop index.
Conditions: This only occurs in an asymmetric routing scenario, where frames are constantly
egressing the etherchannel destined for certain MAC addresses, but frames are not consistently seen
from those MAC addresses. This is often the case when Hot Standby Routing Protocol (HSRP) is
running, and this particular switch is the HSRP standby.
Workaround: Through tweaking ARP and MAC address aging timers, this situation can be avoided.
We recommend that the MAC address aging timer be set at least 3 times higher than the ARP timer
for the VLAN interface.
The configuration for this is:
Switch(config)#mac-address synchronize
Switch(config)#mac-address aging-time 900
Switch(config)#interface Vlan360
