Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCsw77205
Symptoms: ES20 line cards crashing in a loop while using a anything over MPLS (AToM) VC with
Cisco Intelligent Services Gateway (ISG).
Conditions: The issue is seen on all the ES20 cards installed in a Cisco 7609 router running Cisco
IOS Release 12.2(33)SRC2.
Workaround: Manually shutdown the AToM interfaces and ISG interfaces to stop the crashes.
CSCsw78939
Symptoms: No new sessions can come up using VPDN after a few days.
Conditions: The root cause is that we leak and run out of SSM switch IDs.
Workaround: There is no workaround.
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.
CSCsw89962
Symptoms: Ping across CE routers fails.
Conditions: Occurs when "bidir" is configured.
Workaround: There is no workaround.
CSCsw92379
Symptoms: Many "IP ARP: Sticky ARP entry invalidated" syslog messages appear, and the RP
reloads unexpectedly.
Conditions: This symptom is observed when a linecard is swapped while thousands of DHCP
snooping bindings are present and the ip sticky-arp command is configured.
Workaround: Configure the no ip sticky-arp command.
CSCsx20566
Symptoms: Traffic through SIP400 stops or SIP400 displays minor error in show mod output.
Conditions: Seen sometimes on doing RPR+ switchover in a chassis that supports hot fabric
synchronization.
Workaround: Reset the line card.
CSCsx21231
Symptoms: SPA-24CHT1-CE-ATM will remain out of service on a SIP-400 because of a missing
API.
Conditions: This issue will be seen during boot up on a Cisco 7600 router with
SPA-24CHT1-CE-ATM and SIP-400.
Workaround: There is no workaround.
CSCsx22512
Symptoms: After clearing the DHCP snooping bindings, renewing from the database and reloading
the line card, snooping bindings are lost.
