Configuring the Interfaces
Step 6 Reenable interfaces by doing the following:
a. Repeat Step 3 to reenable an interface. Substitute the no shutdown command for the shutdown
command.
b. Repeat Step 4 to write the new configuration to memory.
Use the copy running-config startup-config command.
c. Repeat Step 5 to verify that the interfaces are in the correct state. Use the
show interfaces command followed by the interface type and interface address of the interface.
For complete descriptions of software configuration commands, refer to the publications listed in the
“Related Documentation” section on page viii.
Performing a Basic Configuration
Following are instructions for a basic configuration: enabling an interface, specifying IP routing, and
setting up external timing on a DCE interface. You might also need to enter other configuration
subcommands, depending on the requirements for your system configuration and the protocols you plan
to route on the interface. For complete descriptions of configuration subcommands and the configuration
options available for serial interfaces, refer to the appropriate software documentation.
In the following procedure, press the Return key after each step unless otherwise noted. At any time you
can exit the privileged level and return to the user level by entering disable at the prompt as follows:
Router# disable

Cisco 7401ASR router show interfaces serial, followed
by slot/port
(port-adapter-slot-number/
interface-port-number)
The example is for interface 0 on a
port adapter in port adapter slot 1.
Router# show interfaces serial 1/0
Serial 1/0 is administratively down,
line protocol is down

this example]
VIP in Cisco 7000 series or Cisco 7500
series routers
show interfaces serial, followed
by slot/port adapter/port
(interface-processor-slot-number/
port-adapter-slot-number/
interface-port-number)
The example is for interface 0 on a port
adapter in port adapter slot 1 of a VIP in
interface processor slot 1.
Router# show interfaces serial 1/1/0
Serial 1/1/0 is administratively down,
line protocol is down
