Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: There is no workaround.
• CSCti37503
Symptoms: RP is dropping IPv6 mcast packet.
Conditions: This symptom happens while sending to SSM group.
Workaround: There is no workaround.
• CSCti68153
Symptoms: QinQ packet header is modified breaking QinQ.
Conditions: This symptom occurs when you use ES+ card on the Cisco 7600 where the pseudowire
encapsulation begins.
Workaround: One possible workaround is to use double vlan tagging before the packet gets to the
ES+ card so that when it pops the first Vlan tag, it will modify the second dummy tag and not the
actual Payload. This issue is also not seen on ES20 card.
• CSCti80956
Symptoms: Traffic outage and duplication is seen during fibre cut in customer deployment.
Conditions: This symptom is seen with traffic reroute, L2/L3 co-existence.
Workaround: There is no workaround.
• CSCtj08597
Symptoms: With the following simple topology, the router crashes when sending IGMP joins from
IXIA:
UUT-----Peer-----Ixia
The peer is a Cisco 7600 router acting as a layer2 (only switchport config towards UUT and IXIA)
box. There are 10 OIF interfaces on UUT.
Conditions: This symptom is observed when doing a SSO switchover.
Workaround: There is no workaround.
• CSCtj15265
Symptoms: The event trace buffer gets wrapped around resulting in met cc log not being available.
Conditions: This symptom is seen when there is a lot of OIF churn.
Workaround: There is no workaround.
Resolved Caveats—Cisco IOS Release 12.2(33)SRD4
Cisco IOS Release 12.2(33)SRD4 is a rebuild release for Cisco IOS Release 12.2(33)SRD. The caveats
in this section are resolved in Cisco IOS Release 12.2(33)SRD4 but may be open in previous Cisco IOS
releases.
• CSCee36959
Symptoms: A Cisco 6500 and Cisco 7600 may rarely and unexpectedly reload with the following
error message on the SUP:
%RPC-SP-2-FAILED: Failed to send RPC request
online_diag_sp_request:get_rp_cpu_info.
Conditions: This occurs very rarely when the MSFC or RP is too busy processing an event and can
not respond to the RPC from the SUP. This is seen only on systems that run native Cisco IOS.
