2651 Clock source question

ckeithjones

Level 1

I have a 2651 with a 4 port serial card. I cannot get any commands to work which might set the clock source. Is there another place in the IOS where I can set this?

Hello Ckeithjones,

clock rate can be set only on a serial interface connected to a DCE cable

in your case

>> DTE V.35 TX and RX clocks detected.

Or you swap the cables or you configure the clock rate on the other side

Hope to help

Giuseppe
