Chapter 5 Configuring the PA-8T-232 Interfaces
Configuring the EIA/TIA-232 Interfaces
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
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.

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 interface 0 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 interface 0 of a
port adapter in port adapter bay 0 of a
Catalyst 6000 family FlexWAN module in
interface processor 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 interface 0 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/
interface-port-number)
The example is for interface 0 of a
port adapter in port adapter slot 4.
Router(config)# interface serial 4/0
Router(config-if)#
Cisco 7200 series routers
interface serial, followed by
slot/port
(port-adapter-slot-number/
interface-port-number)
The example is for interface 0 of a
port adapter in port adapter slot 6.
Router(config)# interface serial 6/0
Router(config-if)#
