Chapter 4 Configuring the PA-A2 ATM CES Port Adapter
PA-A2 ATM CES Configurations
Performing a Basic Interface Configuration
Following are instructions for a basic configuration, which includes 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 the
interfaces of your port adapter, 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 command, followed by the type of
interface and the interface address of the interface you plan to configure. (The command for your port
adapter will be specific to the technology of your interface.) The
“Using the show interfaces Command”
section on page 4-17
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.
Step 5
Reenable the interfaces using the no shutdown command. (See the
“Shutting Down an Interface”
section on page 4-3
.)
Step 6
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 7
Write the new configuration to NVRAM as follows:
Router# copy running-config startup-config
[OK]
Router#
The system displays an OK message when the configuration has been stored in NVRAM.
Note
If you are going to disconnect or reconfigure the ATM interface cable, use the shutdown command
before doing so. After reattaching the ATM interface cable, use the no shutdown command to bring up
the ATM interface.
