Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: Shut the VRF interface, clear the prefix from the routing table, then no shut the VRF
interface.
• CSCsw82507
Symptoms: DPM on secondary Cisco Intelligent Services Gateway (ISG) does not clear its session
despite the fact that a DHCP termination message is sent. Even though the binding is cleared, the
session persists until the idle timeout expires or the session is manually cleared.
Conditions: Occurs when multiple DHCP relay agents are present between clients and DHCP server.
Workaround: The session may expire due to idle timeout or be manually cleared.
• CSCsw85986
Symptoms: Traffic through multilinks drop in one direction as some bundles show lost fragments,
causing input errors to increment. The SPA receives the required sequence after long time from the
line card, and time out is less in SPA.
Conditions: Problem is seen when there are more member links in a bundle on SPA-1xCHOC12/DS0
bidirectional traffic is sent. Some bundles drop packets at ingress as lost fragments in one direction.
Workaround: There is no workaround.
• CSCsw88324
Symptoms: The ESM20G, 7600-ES20-GE3CXL, indicates Major error on show module.
Conditions: No special configuration conditions are needed to reproduce. The online diagnostics
status indicates “Major Error”. The major error can be observed following a forced switchover using
the redundancy force-switchover command.
Workaround: No workaround known. Only reloading the router may cause the ESM20G to recover
and pass online diagnostics.
• CSCsw89574
Symptoms: Under certain circumstances when a route entry containing a repair path is updated or
deleted, the repair path may not be properly removed. This may result in the repair path being
orphaned in memory consuming a 60 byte memory block.
Conditions: Occurs with mVPN/TE and multicast enabled on a BGP speaking router. All images
based on Cisco IOS Release 12.2(33)SR may be impacted by this problem.
Workaround: There is no workaround.
• CSCsw89720
Symptoms: When we perform SNMP query (getmany) on cbQosPoliceStatsTable and
cbQosREDClassStatsTable, CPU utilization reaches 99% with a single SSH session. If we query
cbQosPoliceStatsTable and cbQosREDClassStatsTable from 18 SSH sessions, CPU-HOG error
message are seen
Conditions: Occurs with a large number of policies defined on a GigE subinterface (~4k).
Workaround: No workaround, other than stopping the query.
• CSCsw89962
Symptoms: Ping across CE routers fails.
Conditions: Occurs when “bidir” is configured.
Workaround: There is no workaround.
• CSCsw90340
Symptoms: Traffic flows with loopback on a Cisco 7200 router.
