clock rate on Serial interfac

Unanswered Question
Sep 18th, 2007


I'm not able to remove the clock rate on my serial interface. Have you an idea how I can remove it ?

Output :

interface Serial0/0/0

no ip address

encapsulation frame-relay IETF


clock rate 2000000

frame-relay lmi-type q933a

I have this problem too.

It will disappear when line comes up with a DTE cable attached. When the interface is to be used as a DCE you will be able to remove it (using: no clockrate) as well once the link is active.

If it accepted the command that implies that it is connected to a DCE cable. What happens if you connect it to DTE cable. In my experience that removes the clock rate command.

Or have you tried the command default clock rate? I am not sure but I think that should set it back to default which is no clock rate.

I try the cli default clock rate but without success. I'll try to connect a DTE cable and try to remove it. Thanks for your answers.

Try defaulting the interface,

conf t

default interface S0/0/0
