Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S3
Conditions: The problem occurs only during the boot-up process. The router:
–
Should have two processors (in this case PRP2) that are running SSO as the redundancy mode.
–
Should be running Cisco IOS Release 12.0(32)SY6e.
–
Should have a high scale (so a large configuration).
–
Should have many MLPPP interfaces.
Workaround: There is no workaround.
Further Problem Description: The standby processor crashes many times during boot-up when the
router has a high scale (a large configuration) and many MLPPP interfaces.
The problem happens on a Cisco 12000 series Internet router with two PRP2s that are working in
SSO mode and that are running Cisco IOS Release 12.0(32) SY6e.
After the reload, exactly when MLPPP is coming up (establishing), the Cisco 12000 series Internet
router suffers high CPU utilization and it loses communication with the standby router for some
seconds. When the timeout occurs (when the time expires), the router requests the standby PRP to
reset.

• CSCsy98079
Symptoms: Although AToM VCs are up, pings are not working between CE routers, and tracebacks
are also observed.
Conditions: When L2TPv3 is used with AToM, connectivity breaks between CE routers.
Workaround: There is no workaround.
• CSCsz01358
Symptom: A linecard crashes continuously when a microcode reload is performed.
Conditions: The interfaces of the crashing linecard are part of port-channel, and traffic is flowing
via that linecard.
Workaround: There is no workaround.
