Which interface is that ? Which cable is attached? Show diag and show controller to know that.

Hi, you should send the full out of the commands requested for us to check on things.

However, if the attached cable is DTE, the only possible reason is a software bug.

i have the same problem. but once the serial interface plugged to a modem this command will disappear and it functions fine.

if you are not using the serial interface then it wont do anything. if you are using the serial interface, and are acting as the DCE (pretty sure its DCE and not DTE) then you must use clockrate command. It is used when you are providing clocking on a serial interface to link up a connection. Normally, the router will determine if you are using a DCE or DTE connection and use the clockrate if it is needed. if there is no connection, then the default is to show the clockrate command, I believe.

basically, if you are not using the interface, then it doesnt hurt to leave it in. if you are using the interface, then it needs to be set to the right value.
