Configuring PA-FE Port Adapter Interfaces 8-7
Use the following sample basic configuration procedure:
Step 1 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 2 The following examples explain how to configure the fastethernet interface:
• For the Cisco 7100 series, Cisco 7200 series, and the Cisco uBR7200 series, at the
prompt specify the first interface to configure by entering the subcommand interface,
followed by the type (fastethernet) and slot/interface (port adapter slot number and
interface number). The example that follows is for thefirst interface of theport adapter
in slot 4:
Router(config)# interface fastethernet 4/0
Note For the Cisco 7206VXR and Cisco 7206 router shelves, the interface specified in
the above example would include a shelf number. For example, the command interface
fastethernet 5/4/0 would specify the first FE interface of the port adapter in slot 4 of
router shelf 5.
• For the VIP2, at the prompt specify the first interface to configure by entering the
subcommand interface, followed by the type (fastethernet) and
slot/port-adapter/interface. The example that follows is for the first interface of the
first port adapter, on a VIP2 in interface processor slot 1:
Router(config)# interface fastethernet 1/0/0
Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to
the interface with the ip address configuration subcommand, as in the following
example:
Router(config-int)# 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 Change the shutdown state to up and enable the interface as follows:
Router(config-int)# no shutdown
Step 6 Configure additional interfaces as required.
Step 7 When you have included all of the configuration subcommands to complete the
configuration, press Ctrl-Z to exit configuration mode.
Step 8 Write the new configuration to nonvolatile memory 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 “Checking the Configuration” section on page 8-9.
