%TDP-3-PTCLREAD: peer x.xx.x0, read failure
This problem may be seen in releases that include the fix for CSCeg74562 but do not have the fix
associated with this defect.
Workaround: There is no workaround.
• CSCsc05492
Symptoms: A GE Engine 2 line card that is configured for EoMPLS and the Carrier supporting
Carrier feature with IPV4 BGP labels on two different dot1q subinterfaces may reset when you enter
the no hw-module slot slot-number shutdown command on the line card.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(31)S or a later release.
Workaround: There is no workaround.
• CSCsc05830
Symptoms: When a PE router has an output policy with the mpls experimental number command
enabled on an egress interface that is configured for LDP, incoming IP packets that match the
number argument are not selected and handled as default packets.
Conditions: This symptom is observed on a Cisco 10720 that functions as a PE router with a single
output policy and no input policy.
Workaround: On the egress interface that is configured for LDP and that has the output policy,
configure also an input policy.
• CSCsc06641
Symptoms: The following error messages and tracebacks are generated on the RP and line card of a
Cisco 12000 series that processes IPv6 multicast traffic:

Symptoms: An Engine 5 line card crashes when the Fabric MIB is polled.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
