Interface Manager Control Process

The interface manager (IM) is the main control process in the Packet Forwarding Infrastructure (PFI)
and runs one copy on each line card (LC), route processor (RP), and distributed route processor (DRP).
The IM process creates interfaces, adds protocols and capsulations, initiates state and MTU walks, and
registers for notification changes.
The following sample output from the show im server activity command with the summary keyword
shows an overall summary of information about the instance of IM on a particular node:
RP/0/RP0/CPU0:router# show im server activity summary
