By connecting Cisco routers back to back by using a serial connection, a clock rate needs to be configured on the serial interface at the DCE side. Which router the DCE is depends of the connected cable.
This can be checked by the following command:
show controllers serial 0
The clock rate can be configured by issuing the following commands:
Clock rate configuration example:
Router(config)# config t
Router(config)#interface serial0
Router(config-if)#clock rate [clock rate]
