Symptom 2: Cisco Express Forwarding (CEF) may not form adjacencies across a 2-port
multichannel T3 port adapter (PA-MC-2T3+) as is indicated in the output of the show cef interface
type number EXEC command (in this example, serial interface 12/0/0/8:0 is used):

% CEF IDB corresponding to Serial12/0/0/8:0 is not found
Condition 2: This symptom is observed on a Cisco 7500 series after a switchover has occurred and
you first add a serial interface, then remove the serial interface, and then add the serial interface
again.

Symptoms: The Simple Network Management Protocol (SNMP) agent may use 99-percent of the
CPU bandwidth of a Route Processor (RP) for an arbitrarily long time (hours or days), without
necessarily generating CPUHOG errors. This situation causes other processes on the router to fail
because these processes do not receive the CPU bandwidth that they require:
