Performing a Basic Interface Configuration
Following are instructions for a basic configuration, which include 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
Router>
Step 1
Enter configuration mode and specify that the console terminal is the source of the configuration
subcommands, as follows:
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Step 2
Specify the first interface to configure by entering the interface serial subcommand, followed by the
interface address of the interface you plan to configure. (The command for your port adapter may be
different, for example, interface atm.)
provides example of the interface serial subcommand for the supported platforms.

Examples of the interface serial Subcommand for the Supported Platforms
Platform
Command
Example
Catalyst RSM/VIP2 in Catalyst 5000
family switches
interface serial, followed by
slot/port
(port-adapter-slot-number/
interface-port-number)
The example is for the first interface of a
port adapter in port adapter slot 0.
Router(config)#
interface
serial 0/0
Router(config-if)#
Catalyst 6000 family FlexWAN module
in Catalyst 6000 family switches
interface serial, followed by
mod_num/bay/port
(module-slot-number/
port-adapter-bay-number/
interface-port-number)
The example is for the first interface of a
port adapter in port adapter bay 0 of a
FlexWAN module in module slot 3.
Router(config)#
interface
serial 3/0/0
Router(config-if)#
Cisco 7120 series routers
interface serial, followed by
slot/port
(port-adapter-slot-number/
interface-port-number)
The example is for the first interface of a
port adapter in port adapter slot 3.
Router(config)#
interface
serial 3/0
Router(config-if)#
Cisco 7140 series routers
interface serial, followed by
slot/port
(port-adapter-slot-number/
nterface-port-number)
The example is for the first interface of a
port adapter in port adapter slot 4.
Router(config)#
interface
serial 4/0
