Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
• CSCec65977
Symptoms: A 4-port serial enhanced port adapter (PA-4T+) may receive packets, even though the
status of the serial interface is “down/down.”
Conditions: This symptom is observed on a PA-4T+ that is installed in a Cisco 7200 series router
and that is connected to a 1-port serial WAN interface card (WIC-1T) that is installed in a
Cisco 2600 series. The serial interfaces of both routers are connected with a CSU/DSU.
The input packet counter of the serial port of the PA-4T+ increments even though the status of the
serial interface is “down/down.” However, the 2600 series functions properly, and the input packet
counter of its serial interface does not increment.
Possible Workaround: Administratively shut down the serial port.
• CSCee48782
Symptoms: An Engine 4 or Engine 4+ line card in a Cisco 12000 series that switches multicast
traffic may reload.
Conditions: This symptom is observed on a Cisco 12000 series when the ip multicast-routing
distributed command is configured.
Workaround: Configure an access control list (ACL) to block ingress traffic with a source address
of 0.0.0.0, as in the following example:
access-list 1 deny 0.0.0.0
access-list 1 permit any
interface pos3/0
ip access-group 1 in
Note that this ACL does not have any effect on multicast traffic because multicast traffic with source
address 0.0.0.0 is dropped anyway by the Reverse Path Forwarding (RPF) check.
• CSCee93598
Symptoms: An LSP ping reports that an LSP is fine although the LSP is unable to carry MPLS
payloads such as VPN traffic.
Conditions: This symptom is observed on a Cisco router when MPLS echo request packets are
forwarded from untagged interfaces that are directly connected to the destination of the LSP ping
and when the IP time-to-live (TTL) value for the MPLS echo request packets is set to 1.
Workaround: There is no workaround.
• CSCef02056
Symptoms: An inter-AS TE tunnel continues to resignal a path that is rejected instead of switching
to a second path.
Conditions: This symptom is observed when the RSVP local policy on the ASBR rejects the path
message because it does not meet the policy.
Workaround: There is no workaround.
• CSCef08173
Symptoms: A VIP in which a PA-2FE port adapter is installed may reload because of memory
corruption that is caused by a hardware issue of the PA-2FE port adapter.
Conditions: This symptom is observed when the VIP and port adapter function under stress, when
the VIP is unable to serve memory read/write requests from the port adapter, and when there are PCI
retry timeouts.
Workaround: There is no workaround.
