Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCtf20154
Symptoms: Max VTemplate limit on RSP720 is 200 and cannot go beyond this number.
Conditions: This symptom is specific to RSP720.
Workaround: There is no workaround.
Further Description: This limit is seen on RSP720. The limit for SUP720 is 1000.
CSCtf22243
Symptoms: High adjacency usage is seen in stats/non-stats region.
Conditions: This symptom is observed when VPNV4 prefixes are getting load balanced across even
number of TE Tunnels that are FRR protected.
Workaround: Change the load-balancing mode to simple and use the clear ip /jointfilesconvert/422273/bgp neighbor *
command.
CSCtf22968
Symptoms: IP multicast cannot be L3-switched between two routed pseudowires.
Conditions: The symptom occurs when routed pseudowire is the ingress and egress interface for
multicast traffic, and an ES20+ is the exit line card. IP unicast traffic is not affected.
Workaround: There is no workaround.
CSCtf27303
Symptoms: On a Cisco router, a BGP session for a 6PE (peer-enabled in AF IPv6 and end-label
configured) with a third-party router, which does not advertise capability IPv6 unicast (not AFI 2
SAFI 1, only AFI 2 SAFI 4) may be torn down right after it establishes, as the Cisco router sends
out an update in the non-negotiated AF IPv6 unicast (AFI/SAFI 2/1).
Conditions: The symptom is observed under the following conditions:
Cisco side: session enabled for IPv6 + send-label. Cisco router is running Cisco IOS
Release 12.2(33)XNE1 and Release 12.2(33)SRE.
Third-party: only capability IPv6 labeled unicast advertised.
Workaround: There is no workaround.
CSCtf29654
Symptoms: Ingress plus egress traffic on ES-20 line card traffic is spanned. The total output traffic
span destination interface is much less than aggregate traffic at ingress.
Conditions: This symptom is seen in Cisco 7600 router having ES-20 as ingress line card and trying
to monitor huge amount of traffic of more than 5 Gbps.
Workaround: There is no workaround.
CSCtf33203
Symptoms: Supervisor crashes due to RPC communication failure SP-RP.
Conditions: This symptom is observed when high temperature is seen on entire device. One module
crosses alarm threshold which generates minor error RPC message.
Workaround: There is no workaround.
