Cross-Platform Release Notes for Cisco IOS Release 12.0S

OL-1617-14 Rev. Q0

Resolved Caveats—Cisco IOS Release 12.0(28)S4

Miscellaneous

• CSCdw76832

Symptoms: Some features may not be applied automatically to MLP or MFR interfaces. Also, in

complex scaled configurations, CPU hogs may occur on a line card during activation or provisioning

of the interfaces.

Conditions: These symptoms are observed on a Cisco 12000 series that runs Cisco IOS

Release 12.0S and this is configured with a with a 1-port channelized OC-12 (DS1) ISE line card.

Workaround: There is no workaround.

• CSCec25942

Symptoms: A POS Engine 2 line card originates a high traffic volume to a downstream router over

a POS link because the same packet is sent over and over.

Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS

Release 12.0(22)S5.

Workaround: There is no workaround.

• CSCed13322

Symptoms: In the show process memory command output, the display of total and free memory

may show more memory than is actually present in the main processor memory of the router. This

is due to an undocumented change in the command output that also includes both processors and I/O

memory pools in the amounts allocated by each process and the totals at the top of the output.

Conditions: This symptom is observed on all Cisco IOS platforms.

Workaround: Use the output of the show memory summary command to determine the individual

amounts of total and free memory in each of the processor memory pools and the I/O memory pool.

• CSCee04893

Symptoms: A Cisco router is not able to forward traffic to a TE tunnel.

Conditions: This symptom is observed on a Cisco 10000 series that runs Cisco IOS

Release 12.0(26)S1 or a later release and that is configured for MLP and MPLS, and that has a TE

tunnel.

Workaround: There is no workaround.

• CSCee55068

Symptoms: On a Cisco router that has L2 PVCs in the AIS alarm state, in addition to sending AIS

cells, the router also sends loopback cells to the customer edge router.

Condition This symptom is observed on a Cisco 12000 series that runs Cisco IOS Release 12.0 S

when the oam-pvc manage command is configured and when the L2 PVC gets enters the AIS alarm

state. However, this caveat is platform-independent.

Workaround: There is no workaround.

• CSCee55297

Symptoms: When you suspend and resume the event manager scheduler and an applet tries to

Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0S or

Release 12.2S. However, the symptom may also occur in other releases.

Workaround: There is no workaround.
