Configuring a Serial Interface


Router(config)#int s0/0

Moves to interface Serial 0/0 mode

Router(config-if)#description Link to ISP

Optional descriptor of the link is locally significant

Router(config-if)#ip address 192.168.10.1 255.255.255.0

Assigns address and subnet mask to interface

Router(config-if)#clock rate 56000

Assigns a clock rate for the interface

Router(config-if)#no shut

Turns interface on


Tip:

The clock rate command is used only on a serial interface that has a DCE cable plugged into it. There must be a clock rate set on every serial link between routers. It does not matter which router has the DCE cable plugged into it, or which interface the cable is plugged into. Serial 0 on one router can be plugged into Serial 1 on another router.
