Loopback testing on a 2610 router

[Kevin Melton]

Forum

I am working at a client site today.  The client has a large Frame Relay Hub Spoke network.  The Hub is at the HQ location, and then there are about 15 spoke sites in remote offices.

We are having an issue with the frame between the HQ and one of the spokes.  We are currently working with our dear friends at AT&T to troubleshoot the issue.  AT&T yesterday was trying to run a local loop test to the router at the remote (spoke) end.  We were working iwth them in trying to put the remote router (which we manage) into a loopback mode.  We were trying to use controller commands

COOP-Rappahanock#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

COOP-Rappahanock(config)#controller ?

% Unrecognized command

COOP-Rappahanock(config)#controller

That we seem to run out of options...

How can we put the subinterface that is the other end fo the frame into loopback mode so that a local loop test can be done between us and AT&T (provider)?

Thanks

Kevin

Not all interfaces types have controller configuration mode.

It would be proably easier and better if you just use a loopback plug into the demarc connector, to place your router ot of the equation.
