Clock Rate on Serial Interfaces

Is there any command that shows me the clockrate/Speed of my Leased Line.

A "Show Controllers S0" for example just shows me that there is RX and TX

Clock detected, but not the Clockrate.

Regards

Re: Clock Rate on Serial Interfaces

this output was taken from a 3660 router.

Router#sh controllers serial 1/0

M4T: show controller:

it shows the clockrate detected from the serial input.
