Frame Relay speed

Unanswered Question
Jun 5th, 2007

Hello,

I would like to know if there is a command allowing me to check the speed of a frame-relay PVC?

I have a router connected to a service provider via a serial line. On the serial line is configured one frame-relay pvc (very basic configuration, hdlc would have been enough). I don't know the speed of the physical line and no traffic shaping has been configured on the pvc. How could I find the speed? I've tried with command such as show interface, show frame-relay pvc, show controller but haven't been able to find it...

Thanks in advance for your help.

Christophe

I have this problem too.

Hi Christophe,

please post your show interface and show controller output.

The command "show interface" reports a bandwidth of 1544Kbit, but I'm absolutly sure the line is slower.

The command "show controller" is not very human friendly...

Try the

SHOW FRAME-RELAY PVC and the

SHOW FRAME-RELAY PVC INTERFACE

commands

These commands do not help much...
