Asynchronous Transfer Mode Interface Processor (AIP) Installation and Configuration 33
Configuring the AIP
Table 5
AIP Configuration Default Values
After you verify that the new AIP is installed correctly (the enabled LED goes on and all cables are
correctly connected), you can configure the new ATM interface. Be prepared with the information
you will need, such as the interface IP address, MTU size, AAL mode, and desired rate queues.
Interface Port Numbering for the ATM Interface
The Cisco 7000 series and Cisco 7500 series routers identify an interface address by its interface
processor slot number and port number in the format slot/port. Because each AIP contains a single
ATM interface, the port number is always 0. For example, the slot/port address of an ATM interface
on an AIP installed in interface processor slot 0 would be 0/0; if installed in interface processor
slot 1, the slot/port address changes to 1/0.
Configuring the Interface
Use the following guidelines to perform 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 additional descriptions of configuration subcommands and the configuration options available
for ATM, refer to the appropriate router system software configuration publications listed in the
section “If You Need More Information” on page 2.
Configuring the AIP first requires privileged-level access to the EXEC command interpreter. Also,
privileged-level access usually requires a password. (Contact your system administrator, if
necessary, to obtain privileged-level access.)
The following steps describe a basic configuration. The system will prompt you for a password if
one is set. Press the Return key after each configuration step unless otherwise noted.
Step 1
At the privileged-mode prompt, enter configuration mode and specify that the console
terminal will be the source of the configuration subcommands as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
