Re: Clock Rate

Things to consider here are :

1) Clock rate is applicable to DCE devices and not on DTE devices
2) Devices can be categorized as DCE or DTE depending the cable connected to
serial interface.
3) Generally DCE devices are FR switch etc.
4) If you are configuring the back to back connection ; configure "clock
rate <> " CLI on DCE end only
5) I think latest IOS on serial HWIC will take clock rate command only on
DCE end and not on DTE end . However older IOS used to take it on any device
6) Any rate is good ... as long as it is working .. default 9600 bps should
be OK .
