PA-T3+ Serial Port Adapter Installation and Configuration
OL-3505-03
Chapter 4 Configuring the PA-T3+
Configuring the Interfaces
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.) Table 4-3 provides examples.
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.
