Bringing-up a Router Interface

Description: By default, an interface will be in shut-down state. We need to issue no shutdown command to bring-up the interface. Notice that the show interfaces command shows that the line protocol is up indicating that the interface is now active (sending and receiving packets).

Instructions:

1. View the information about interface serial 0

2. Bring serial 0 to no shutdown state

3. Now view the state of the interface serial 0
