Reference Guide for the Model RT328 and Model RH348 ISDN Routers

Packet Tracing

You can diagnose PPP connection failures using the packet trace feature of the Model RT328/

RH348 router.

To invoke the packet trace:

1.Access the internal Manager of the router using a serial or Telnet terminal connection.

2.If you will be tracing an outgoing call, go to Menu 11 (Remote Node Setup) and note which remote node number, N, corresponds to the location you will be calling.

3.Invoke the Command Interpreter Mode (Menu 24.8).

4.Clear any existing trace information by entering:

rt328> sys trcl cl

5.Turn on the trace log by entering:

rt328> sys trcl sw on

6.Turn on the packet trace by entering:

rt328> sys trcp sw on

7.Trace the call.

To trace an outgoing call, force the router to dial the remote node by entering:

rt328> isdn dial N

(N is the remote node number shown in Menu 11.)

Or, to trace an incoming call, enable incoming trace by entering:

rt328> sys event

8.Wait for the desired activity, and then display the trace log by entering:

rt328> sys trcl disp

The trace appears on the screen as in Figure D-2. Use PageUp and PageDown to inspect the entire trace.
