Setting up a Serial Interface

Lab 1 – Setting up a Serial Interface

The first lab in this lab series is to understand how to setup a serial connection. When
Serial connections are configured they need one more command that normal Ethernet
connections do not. That command is the clock rate command. The clock rate command
establishes a common rate at which the sending and receiving routers will send data to
each other. It should be noted that if using a service provider circuit, there is no need for
the clock rate command since the service provider provides the clocking. Establish a
simple serial to serial connection between Router 1 Serial 0 and Router 2 Serial 0. To
verify your connection is established use the command show cdp neighbors. This
command will show the cdp information of your directly connected neighbor.

 

R1:
hostname router1
!
interface Serial0
clock rate 64000
no shut

R2:
hostname router2
!
interface Serial0
no shut
