Hi community,

is it possible to see the clock rate configured on the DCE side on the DTE side of a serial interface?

Yes its possible issue the command:

on both sides

Hi,

sure on the DCE side this would show the clock rate. But where do you see the clock rate on the DTE side with "show controller"?

Can you post an example?

Regards, Martin

Only certain platforms and cards will show the received DTE clock in "show controller". Others will just say "TX and RX clocks detected".

Sample output on my 1941 router:showcontroller.JPG

The number shown is 1917381 +/- 10%.

 

Which would imply a clock rate of 2000000.

 

My answer is a little late to the party, but maybe this will help the next person as the existing answers did me.

 

I connected three c3745 routers and I gave clock rate 250000 command to R1 and R2 not synchronized with R1 and R3 though (Showing different value for show controllers). I gave same command to the R2 but got same result, can any one please let me know the issue.
