Removing and Replacing the Input/Output Controller
Note The Cisco 7200 series routers and Cisco uBR7200 series routers identify interfaces by port
adapter slot number and interface port number. Port adapter slot 0 in the Cisco 7200 series routers
and Cisco uBR7200 series routers is always reserved for the Fast Ethernet port on the I/O controller.
Therefore, the address of the Fast Ethernet port on the I/O controller (if present) in Cisco 7200 series
routers or Cisco uBR7200 series routers is always 0/0.
The Cisco 7206 router shelf identifies interfaces by shelf number, port adapter slot number, and
interface port number. The shelf number is a number assigned to the router shelf during the initial
configuration of the Cisco AS5800 Universal Access Server. Port adapter slot 0 in the Cisco 7206
router shelf is also reserved for the Fast Ethernet port on the I/O controller. Therefore, the address
of the Fast Ethernet port on the I/O controller (if present) in a router shelf is x/0/0, where x is the
shelf number. For information about the Cisco 7206 as a router shelf in a Cisco AS5800 Universal
Access Server, refer to the Cisco AS5800 Universal Access Server documentation listed in the “If
You Need More Information” section on page 2.
Step 1
At the privileged-level prompt, enter configuration mode and specify that the console
terminal will be 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 Fast Ethernet port on the I/O controller interface to configure by entering the
interface fastethernet 0/0 command as follows:
Router(config)# interface fastethernet 0/0
Note In a Cisco 7206 router shelf, the interface specified in Step 2 would include a shelf
number. For example, the command interface fastethernet 5/0/0 would specify the Fast
Ethernet interface on the I/O controller (slot 0) in router shelf 5.
Step 3
If IP routing is enabled on the system, assign an IP address and subnet mask to the
interface with the ip address subcommand as follows:
Router(config-int)# ip address 1.1.1.10 255.255.255.0
Step 4
If you installed an I/O controller with the Fast Ethernet port that is equipped with an MII
receptacle and an RJ-45 receptacle, use the media-type command to specify the I/O
controller’s media type; the default is the RJ-45 receptacle. The following example
configures the MII receptacle as the media type for the I/O controller:
Router(config-if)# media-type mii
Note Use the media-type 100BaseFX command to return the media type to the RJ-45
receptacle.
Step 5
Use the full-duplex command to specify full-duplex transmission mode for the Fast
Ethernet port on the I/O controller; the default is half-duplex mode. The following
example configures full-duplex mode:
Router(config-if)# full-duplex
