Troubleshooting IPM

Q.What does the “Responder On” field mean in Target Configuration?

A.Rtr responder enables you to capture the jitter statistics, if you have enabled this feature on a device.

You can enable this feature from the router by using this command:

rtr responder

Rtr responder was introduced from SAA Version 2.1.1. In SAA 2.1.1, there was no MIB variable to provide the status, so IPM captured the status as “Unknown”. From SAA version 2.2.0, the MIB variable has been made available, so the status is displayed now as Yes or No, depending on the responder status.

If the target is not of type 'RTR responder,' then the field would give “N/A”.
