Check Clock Rate on DCE device?

mguy

Where would I go or what command should I use to check the clock rate on a serial line on a DCE device?

Thank you!

in a lab environment, on a router, it's "show controllers".

i'm getting a different output. I have a sim using a 2811 router. Help?

3rd line down. End of line: DCE cable.

This would be the end where you would use "Clock rate". If memory serves me, You can use the clock rate on the DTE side, but it's not going to affect anything. It just matters when you don't use it.

I don't see it? I set it to 64000..

Wait, you're asking to see the speed?

show interfaces interface.

4th line down: It's the "BW" information.

I'm looking for the "clock rate" speed between serial connection (on the DCE equipment) not the theoretical bandwidth of the line.

I imagined if I issued the following commands on serial 0/0

"clock rate 64000"

this value (64000) will show up somewhere..

Try a "sh controllers s0/0" instead of "sh controllers"

Otherwise, I don't know. I tried scouring google and didn't find anything different than what I had told you.
