Chapter 4 Configuring the PA-2FEISL
Configuring the Interfaces
Configuring the Interfaces
After you verify that the new PA-2FEISL 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-2FEISL 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-2FEISL that
was previously configured, the system recognizes the new interfaces and brings each of them up in their
existing configuration.
For a summary of the configuration options available and instructions for configuring interfaces on a
PA-2FEISL, refer to the appropriate configuration publications listed in the
.
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
privileged level of the EXEC.)
You can configure each of the interfaces on a PA-FEISL at:
•
100 Mbps, half duplex; 200 MBps is the maximum aggregate of the 2 ports
Half duplex operation is the default.
•
200 Mbps, full duplex; 400 MBps is the maximum aggregate of the 2 ports
You can also configure one PA-2FEISL interface at 100 mbps, half duplex, and the second PA-2FEISL
interface at 200 Mbps, full duplex; 300 Mbps is the maximum aggregate of the two ports.
This section contains the following subsections:

Performing a Basic Configuration
Following are instructions for 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 complete descriptions of
configuration subcommands and the configuration options available for fast Ethernet interfaces, 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:
