3. attach to the ingress module and use the same commands as step 2 and compare the values, if
the destination mac address is not the same there is hardware forwarding corruption. Note: The
adjacency index will be a different number on the module dfc.

Conditions: The Cisco 7600 must have a distributed forwarding card installed on the ingress module
and be configured as an MPLS PE router. The problem is only observed after a router reload,
upgrade, or crash.
Workaround: Reloading the ingress module will resolve the hardware forwarding corruption on the
module:
hw-module module module number reset
• CSCti24657
Symptoms: New settings for fabric channel preemphasis are for sip600/esm20 card for Cisco 7609,
Cisco 7609S, and Cisco 7613 chassis.
Conditions: There are no conditions.
Workaround: There is no workaround.
• CSCti37167
Symptoms: A router crashes.
Conditions: This symptom occurs after router compares the snmp value of
mplsTunnelLastPathChange.
