Symptoms: IS-IS, OSPFv2/OSPFv3 adjacencies, or BGP neighbourships across any of the
interfaces of an Engine 2 line card may fail.
Conditions: This symptom is observed on a Cisco 12000 series when the CPU of the Engine 2 line
card is oversubscribed in terms of its maximum IPv6 packet-per-second forwarding rate (which is
about 100 Kpps). (IPv6 traffic forwarding on an Engine 2 line card is performed by the CPU of the
line card.)
Workaround: There is no workaround.
• CSCed82102
Symptoms: The match atm-clp command and the match not atm clp command may not be present.
Conditions: This symptom is observed in Cisco IOS Release 12.0(28)S.

Symptoms: Line card instability may occur when passing MVPN traffic on an Engine 3 line card
with slowpath running, and then configuring hardware multicast while traffic is running.

PE router with an Engine 3 Quad OC-12 line card forwarding multicast packets on a VRF interface.
Workaround: There is no workaround.
• CSCed83044
Symptoms: A standby RSP may reload with the following error message:
%SYS-6-STACKLOW: Stack for process IPC Seat Manager running low
Conditions: This problem happens on a Cisco 7500 series router that runs Cisco IOS
Release 12.0(27)S with IOPS when RPR, RPR+ or SSO redundancy modes are configured and when
certain ATM subconfiguration commands such as the connect command are executed on the active
RSP.
Workaround: There is no workaround.
