Configuring an Unchannelized T3 Link
Performing a Basic Serial Interface Configuration
Following are instructions for a basic configuration: enabling an interface and specifying IP routing. 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# configuration 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. See “Port Adapter Slot Locations on the
Supported Platforms” section on page 1-5 and “Identifying Interface Addresses” section on page 1-11.
This example is for the serial interface of T3 port 0 in port adapter slot 6.
Router(config)# interface serial 6/0
Router(config-if)#
This example is for the serial interface of T3 port 0 of a port adapter in port adapter slot 1 of a VIP in
interface processor slot 2.
Router(config)# interface serial 2/1/0
Router(config-if)#
Step 3 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using
the ip address subcommand, as in the following example:
Router(config-if)# ip address 10.0.0.0 10.255.255.255
Step 4 Add any additional configuration subcommands required to enable routing protocols and set the
interface characteristics.
Step 5 Re enable the interfaces using the no shutdown command. (See the “Replacing an Existing Port
Adapter” section on page 4-2.)
Step 6 Configure all additional port adapter interfaces as required.
Step 7 After including all of the configuration subcommands to complete your configuration, press
Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode
and return to the EXEC command interpreter prompt.
Step 8 Write the new configuration to NVRAM as follows:
Router# copy running-config startup-config
[OK]
Router#
