Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
• CSCte78165
Symptoms: Device may reload when the show ip protocol command is issued.
Conditions: The symptom is observed when routing protocol is configured and the ISIS routes are
being redistributed.
Workaround: Do not use the show ip protocol command.
• CSCte79777
Symptoms: There is a CPU hog and the router crashes.
Conditions: The symptom is observed when the syslog is configured with a “logging discriminator”,
for example:
logging discriminator TB msg-body includes Trace
logging trap debugging
logging host 1.1.1.1 discriminator TB
Workaround: Remove “discriminator” from syslog (e.g.: replacing “logging host 1.1.1.1
discriminator TB” with “logging host 1.1.1.1”).
• CSCte91656
Symptoms: Flooding of traffic for known unicast MAC on the VPLS VCs seen after FRR cutover,
reopt, or SSO switchover.
Conditions: The symptom is observed with ES-20 as the access interfaces and having port-channel
member interfaces. It is seen when you configure “ve EVC under port-channel” with bridge domain
and VPLS configuration.
Workaround: Flap the pseudowire.
• CSCtf00132
Symptoms: A Cisco 7200 series router crashes when there are unauthenticated sessions in a
multichassis SGBP environment.
Conditions: The symptom is observed when multiple unauthenticated sessions in a multichassis
multilink PPP SGBP environment are dialed from the same client on multiple home gateways as part
of the same session.
Workaround: There is no workaround.
• CSCtf06442
Symptoms: The newly active supervisor on a Cisco 7600 router with SSC-400 may crash shortly
after SSO failover due to a large amount of traffic causing system instabilities.
Conditions: This behavior is seen on a Cisco 7600 router that is running Cisco IOS
Release 12.2(33)SRC5.
Workaround: Configure MLS rate limiters to prevent RP from being overwhelmed, which may
prevent the router from crashing.
• CSCtf06486
Symptoms: SSO failover may be delayed by approximately 10 seconds when SSC- 400 is present in
chassis.
SSC-400 is not SSO aware. However other line cards may be affected by this.
Conditions: The following error message can be seen:
oir_enable_switching_for_modules_replied: Slot: 7 (nonEMS20g) took > 10000 ms extra to
reply
Workaround: There is no workaround.
