Interface Manager Distributor Overview
The IMD is an aggregation service. The following elements are supported:

• Discovers information about each control node in each interface manager service on each card
through the GSP.
• Contains the interface name, handle, state, MTU, and capsulation state.
Table 3-1 List of Reasons for Missed Interface Manager Notifications
Reason Solution
Client is not connected to IM. Check the client connection by using the show im client
command with the info keyword.
IM is not running. Check the interface manager by using the show process
command with the ifmgr keyword.
Client is not getting pulses from IM. Check to see if the client is blocked by using the show
process command. Use the debug im callbacks command
to debug the callbacks from the IM.
Client is processing the notifications
slowly and has notifications queued.
Use the show im client command with the notify keyword
to see the activity of the IM.
