Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S4
Conditions: This symptom is observed on a Cisco 12000 series that has a channelized ISE ingress
line card when packets are replicates to a VRF interface on the ingress line card, to a VRF interface
on another line card, and to a core interface on a third line card. This symptom occurs only after
some redundancy switchovers.
Workaround: Reload the line card.

Symptoms: A bad checksum error, bad LLS TV length error, or both are reported on a router that is
configured for OSPF and BGP. These protocols or other configured protocols may flap during the
errors, and data packets that are sent to the RP may be lost.
Conditions: These symptoms are observed on a Cisco router when the following conditions are
present:
OSPF, BGP, and other control protocols are configured with scaled routes and peers.
Congestion occurs on the RP because of the control packets that are targeted to the RP in the
router. Also, if additional traffic is sent to one of the IP addresses of the router, the packets are
terminated on the RP. For example, IP ping packets that are directed towards one of the loopback
addresses are terminated on the RP.
Workaround: There is no workaround.
CSCej01743
Symptoms: Traffic drops may occur when traffic is sent over MFR or Frame Relay links.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S1 or a later release and that is configured for software forwarding.
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.
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Conditions: This symptom is observed when a source is no longer active when using the show ip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.
CSCej22910
Symptoms: Multicast traffic does not reach a CE which is connected via static IGMP joins to PE.
Conditions: The DecapPE should have a Tx line card with one port toward the core and another port
toward the edge. Traffic from EncapPE is toward the CE. There should be static joins at DecapPE
with SSM configured.
Workaround: There is no workaround.
CSCej26744
Symptoms: The show policy-map command on the POS E3 and E6 interface is not working
properly.
