Resolved Caveats—Cisco IOS Release 12.0(28)S2

Workaround: Change the default merge algorithm to POD by entering the hw-module slot

slot-number reload command for the slot in which the affected line card is installed.

Alternate Workaround: To avoid problems with the policy map modification, remove the service

policy from the interface, modify the service policy, and reattach the service policy to the interface.

• CSCef89562

Symptoms: An Engine 4+ EPA-GE/FE-BBRD line card reports “%TX192-3-PAM_MODULE” and

“%TX192-3-PAM_PIM” errors, and the interfaces continue to flap with the following error

message:

%GRPGE-6-INVALID_WORD: Interface GigabitEthernet15/1/0: Detected RX Invalid Word

When there is heavy traffic, the line card may crash without generating any crashinfo.

Workaround: There is no workaround.

• CSCef91030

Symptoms: After the default route is received from a remote PE for a VRF, communication stops for

traffic via the default route in this VRF on a Cisco 12000 series that functions as a PE router in an

MPLS VPN environment. The packets are switched out of the core MPLS interface untagged as

native IPv4 packets instead of with MPLS and BGP labels.

Conditions: This symptom is observed when the traffic is received from VRF interfaces on an

Engine 2 line card that is installed in a Cisco 12000 series that functions as a PE router.

The symptom occurs in Release 12.0(27)S2, Release 12.0(27)S3, and interim releases for Cisco IOS

Release 12.0(30)S. Other releases may be affected too. The symptom does not occur in

Release 12.0(24)S2.
