Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: When removing PA-MC-8TE1+ from the chassis, the router has an unexpected system
reload. This reload happens when you remove the port adapter and the router is running the Cisco
IOS bootloader image. Also happens when the port adapter is removed after the router finishes
loading the Cisco IOS bootloader image and before it loads the complete Cisco IOS Software image.
Conditions: This occurs on a Cisco 7200 VXR NPE-G2 Series Routers on the Cisco IOS bootloader
image from the Cisco IOS Release 12.4(4)XD.
Workaround: Remove PA-MC-8TE1+ when the complete Cisco IOS Software Image finishes
loading.
CSCsu76800
Symptoms: “Acct-Input-Giga-word” and “Acct-Output-Giga-wor” attributes are missing in the
Accounting request packets.
Conditions: The symptoms are observed when you send traffic that requires the giga word counters
to be incremented.
Workaround: There is no workaround.
CSCsu77549
Symptoms: Protocol Independent Multicast (PIM) VPN routing/forwarding (VRF) neighbors not
formed.
Conditions: Occurs after line card reload.
Workaround: Delete and add back the MVPN configuration.
CSCsu78559
Symptoms: In scaled conditions (8000 IP sessions) with SACL applied, line card memory leaks over
a period of 4-5 hours. Sometimes this even results in a line card crash. The “Sacl Np Client” task
occupies most of the CPU, and a large number of IP sessions (around 10% of 8k) will be in feature
pending status, with ACL pending flag set.
Conditions: Occurs under scaled conditions with approximately 8000 IP sessions, with the same
SACL applied to all IP sessions.
Workaround: There is no workaround.
CSCsu79340
Symptoms: Cisco router crashed while Intermediate System-to-Intermediate System (IS-IS) is
coming up.
Conditions: Occurred only on a Cisco router running Cisco IOS Release 12.2(33)SRC2 with “mpls
traffic-eng multicast-intact” configured under “router isis”.
Workaround: Disable “mpls traffic-eng multicast-intact” configuration.
CSCsu81406
Symptoms: Following a processor switchover in route processor redundancy (RPR) plus mode, the
SM-1CHOC12/T1-SI card on the channelized serial interfaces goes down.
Conditions: Occurs after the processor switchover in RPR plus mode.
Workaround: Use hw-module reset to solve the issue.
CSCsu81838
Symptoms: Memory leak occurs.
Conditions: Occurs during normal operations.
Workaround: There is no workaround.
