Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
CSCej15698
Symptoms: The output of the show ip mroute vrf vrf-name active command shows an incorrect
entry or rate for decapsulated traffic.
Conditions: This symptom is observed on a Cisco 12000 series that is configured for mVPN.
Workaround: There is no workaround.
CSCej15940
Symptoms: The Queue Manager may not converge on a 4-port OC-12 ATM ISE line card or a 1-port
channelized OC-12 ISE line card, and tracebacks may be generated.
Conditions: This symptom is observed on a Cisco 12000 series that runs the c12kprp-p-mz image
and occurs after the router has reloaded.
Workaround: There is no workaround.
CSCej16004
Symptoms: An MTU change on a multilink bundle interface takes no effect for SPA interfaces. This
situation may cause the traffic to be dropped.
Conditions: This symptom is observed on a Cisco 12000 series when you change the MTU on a
multilink bundle interface and when you change the traffic generation accordingly.
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.
CSCej22910
Symptoms: Multicast traffic does not reach a CE router that is connected via static IGMP joins to a
PE router.
Conditions: This symptom is observed when the following conditions are present:
Traffic from the PE router that performs encapsulation flows towards the CE router.
The PE router that performs decapsulation has an egress line card with one interface connected
to the core of the network and another interface connected to the edge of the network.
The PE router that performs decapsulation has static joins that are configured for Source
Specific Multicast (SSM).
Workaround: There is no workaround.
CSCej23284
Symptoms: In an ATM L2VPN configuration, the protocol of some ATM interfaces on a customer
edge (CE) router may be in the DOWN state, causing the corresponding PVCs to be in the DOWN
state too.
Conditions: This symptom is observed rarely when an RP switchover occurs on the connected
provider edge (PE) router.
