Chapter 4 Configuring the PA-2FE

Configuring the Interfaces

Configuring the Interfaces

After you verify that the new PA-2FE is installed correctly (the ENABLED LED goes on), use the privileged-level configure command to configure the new interfaces. Have the following information available:

•Protocols you plan to route on each new interface

•IP addresses, if you plan to configure the interfaces for IP routing

•Bridging protocols you plan to use

If you installed a new PA-2FE or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the new interfaces. If you replaced a PA-2FE that was previously configured, the system recognizes the new interfaces and brings each of them up in their existing configurations.

You can configure each of the interfaces on a PA-2FE at:

•100 Mbps, half duplex, for a maximum aggregate bandwidth of 200 Mbps per pair. Half-duplex operation is the default.

•200 Mbps, full duplex, for a maximum aggregate bandwidth of 400 Mbps per pair.

You can also configure one PA-2FE interface at 100 Mbps, half duplex, and the second PA-2FE interface at 200 Mbps, full duplex, for a maximum aggregate bandwidth of 300 Mbps per pair.

For a summary of the configuration options available and instructions for configuring interfaces on a PA-2FE, refer to the appropriate configuration publications listed in the “Related Documentation” section on page viii.

You execute configuration commands from the privileged level of the EXEC command interpreter, which usually requires password access. Contact your system administrator, if necessary, to obtain password access. (See the “Using the EXEC Command Interpreter” section on page 4-1for an explanation of the privileged level of the EXEC.)

This section contains the following subsections:

•Performing a Basic Interface Configuration, page 4-7

Shutting Down an Interface

Before you remove an interface that you will not replace, or replace port adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured port adapter. When you shut down an interface, it is designated administratively down in the show command displays.

Follow these steps to shut down an interface:

Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the “Using the EXEC Command Interpreter” section on page 4-1for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the source of the configuration commands, as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#
