Chapter 4 Configuring the PA-8E

Configuring the PA-8E Interfaces

After you verify that the new PA-8E 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-8E 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-8E that was previously

configured, the system recognizes the new interfaces and brings each of them up in their existing

configurations.

Note The PA-8E interfaces can both be configured at 10 Mbps, full duplex (FDX), for a maximum aggregate

bandwidth of 80 Mbps.

For a summary of the configuration options available and instructions for configuring interfaces on a

PA-8E, 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 4-1 for an explanation of the

privileged level of the EXEC.)

This section contains the following subsections:

• Shutting Down an Interface, page 4-2

• Performing a Basic Interface Configuration, page 4-8

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 4-1 for instructions.)

Step 2 At the privileged-level prompt, 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 3 Shut down interfaces by entering the interface ethernet subcommand (followed by the interface address

of the interface), and then enter the shutdown command.
