PA-2FE-TX and PA-2FE-FX Two-Port Fast Ethernet Port Adapter Installation and Configuration
OL-3474-06
Chapter 4 Configuring the PA-2FE
Checking the Configuration
Note
The PA-2FE is automatically configured with 100-Mbps interfaces. If Cisco IOS software detects that
the PA-2FE is connected to a 10-Mbps interface, the PA-2FE will automatically be configured to run at
10-Mbps. Use the
speed [10 | 100 | auto]
command to manually set the Fast Ethernet speed.
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 commands required to enable routing protocols and set the interface
characteristics.
Step 5
Reenable the interfaces using the
no shutdown
command. (See the
“Shutting Down an Interface” section
on page 4-2
.)
Step 6
Configure all additional port adapter interfaces as required.
Step 7
After including all of the configuration commands 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. To check the interface configuration
using
show
commands, proceed to the following section, “
Checking the Configuration
.”
Checking the Configuration
After configuring the new interface, use the
show
commands to display the status of the new interface
or all interfaces, and use the
ping
command to check connectivity. This section includes the following
subsections:
