Chapter 4 Configuring the PA-2FEISL
Configuring the Interfaces
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 fastethernet
subcommand, followed by
the interface address of the interface you plan to configure.
gives 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
“Performing a Basic Configuration”
Step 6
Configure all additional port adapter interfaces as required.
Step 7
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 8
Write the new configuration to NVRAM as follows:
Router#
copy running-config startup-config
[OK]
Router#
This completes the procedure for creating a basic configuration.
