Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S6
Workaround: There is no workaround.
• CSCej04738
Symptoms: After you have reloaded the router, an input service policy on an interface of a 1-port
channelized OC-12 ISE line card that is configured for MLP may become stuck in the suspended
mode.
Conditions: This symptom is observed on a Cisco 12416 that runs Cisco IOS Release 12.0(28)S4
and that is configured with two Performance Route Processors (PRP-1s), one 1-port channelized
OC-12 ISE line card, one 4-port OC-3 POS ISE line card, two 1-port OC-48 POS ISE line cards,
three OC-192 POS E4+ line cards, and one 4-port GE ISE line card.
Workaround: Delete and reconfigure the service policy.
• CSCej07539
Symptoms: Multicast traffic does not resume fully after you have removed the active PRP from the
router.
Conditions: This symptom is observed on a Cisco 12000 series that runs the c12kprp-p-mz image of
Cisco IOS Release 12.0(28)S4 and that is configured with redundant PRPs that function in RPR+
mode. The router has two channelized OC-12 line cards that are configured with mVPNs.
Workaround: There is no workaround.
• CSCej12324
Symptoms: A Cisco 10000 series drops a packet for a prefix with an incomplete CEF adjacency.
Conditions: This symptom is observed when the PXF engine does not punt the packet with the
incomplete CEF adjacency to the RP (as it is supposed to do) but drops the packet.
Workaround: Send a ping for the prefix with the incomplete CEF adjacency in order to complete the
CEF adjacency.
• CSCej14847
Symptoms: Auto-RP messages from a CE router are lost.
Conditions: This symptom is observed when you enter the clear ip mroute * on a connected PE
router. The messages do not recover by themselves.
Workaround: To restart Auto-RP messages, enter the clear ip mds linecard command.
Alternate Workaround: To restart Auto-RP messages, debug the VRF Auto-RP by entering the
debug ip pim vrf vrf-name auto-rp.
• CSCej15682
Symptoms: When multicast traffic is being sourced from different sources, and one of the sources
is removed, the show ip mroute vrf command for the VRFs still shows that source as active.
Conditions: This symptom is observed when a source is no longer active when using the show ip
mroute vrf command.
Workaround: There is no workaround.
• CSCej20986
Symptoms: An Engine 4 ingress line card may enter an incorrect carving state in which it sends all
packets that are larger than 608 bytes to the buffer size pool (freeq) of the wrong egress line card,
causing all packets that are larger than 608 bytes to be dropped. The symptom is especially
noticeable when the egress line card is an Engine 2 line card.
Conditions: This symptom is observed rarely on a Cisco 12000 series.
Workaround: Reload the Engine 4 ingress line card.
