Command sh controller to detect line speed

Unanswered Question
Oct 30th, 2007

If I perform the following command on a cisco 72xx series, I get an output which is showing me the speed the serial port is getting from the Csu/dsu.

The same command performed on the cisco 17xx; 18xx;26xx;28xx series never showes the clockrate. Is it impossible to get it or there is another way? Since sometimes Ptt set wrong speed on the csu/dsu it could be important check on the router which speed is detecting

7206vxr#sh controller s2/5

M8T-V.35: show controller:

DCD=up DSR=up DTR=up RTS=up CTS=up

line state: up

cable type : V.35 DTE cable, received clockrate 2047212<<<<<<<<<<<<<<<<<<<<<<<

I have this problem too.

received clock measured is available only on certain HW interfaces. There is no way to obtain the clock info where not supported.

Hope this helps, please rate post if it does!
