Troubleshooting the Trace Logs for the Interface Manager
To debug the problem that occurred on the router and the IM, use the show im trace command with both
the location and internal keywords to trace logs that are recovered from the router for the applicable
location.
The debug im errors command enables the server for error debugging. When the problem is narrowed
down, debugging is enabled to provide more information.
The debug im callbacks command is used to display when notifications are arriving at the clients from
IM or Interface Manager Distributor (IMD). In addition, the command checks to see the number and
types of messages that are in the set of notifications.
