Troubleshooting the Registrations for the Interface Manager
When the interfaces and control nodes are created, various processes want to obtain information that
includes the notifications of the state, MTU, and existence.
You can use the show im registrations command to see which clients are registered with the IM. With
the exception of the all option, the other options filter the table to show only the rows of a certain type.
The location keyword is used to direct the command to a specific IM. The job ID (JID) is used with the
show process command to find more information about the client process, or with the show im server
activity command with the client-info keyword to find out more about the client connection to the IM.
The following sample output from the show im registrations command shows all the IM registrations:
RP/0/RP0/CPU0:router# show im registrations all

The registered client receives the changes for the IM notifications. If a client appears to be missing
notifications, see the possible reasons in Table 3-1.
