OL-1617-14 Rev. Q0
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.

router(config)#map-class frame-relay r
router(config-map-class)#frame-relay ?
adaptive-shaping Adaptive traffic rate adjustment, Default = none
bc Committed burst size (Bc), Default = CIR
be Excess burst size (Be), Default = 0 bits
cir Committed Information Rate (CIR), Default = 56000 bps
custom-queue-list VC custom queueing
fecn-adapt Enable Traffic Shaping reflection of FECN as BECN
mincir Minimum acceptable CIR, Default = 1/2 CIR
priority-group VC priority queueing
traffic-rate VC traffic rate
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS Release 12.0S.
Workaround: There is no workaround.
• 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.
Conditions: These symptoms are observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(26)S3 or Release 12.0(27)S3.
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.
