controller with the Fast Ethernet port. The text “Port adapter disabled” in the command output

indicates that the Fast Ethernet port on the I/O controller is disabled.

Additionally for the Cisco 7202, the following message appears in the system banner if an I/O

controller with the Fast Ethernet port is installed in the system:

%C7200-3-UNSUPPORTED: FE in slot0 is not supported on C7202 chassis

If the above message appears, the Fast Ethernet port on the I/O controller is automatically disabled.

If the above message does not appear, your Cisco 7202 has an installed I/O controller without the

Fast Ethernet port.

The RJ-45 receptacle is the default media type for the I/O controller equipped with an MII receptacle

and an RJ-45 receptacle. Use the media-type command to change the I/O controller’s media type

and the show interfaces command to verify the change. The following example conﬁgures the MII

receptacle as the media type for the I/O controller:

Router# config t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# interface fastethernet 0/0

Router(config-if)# media-type mii

Router(config-if)# no shutdown

Router(config-if)# exit

Router(config)#

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed

state to up

%LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up

Router# sh interface fastethernet 0/0

FastEthernet0/0 is administratively up, line protocol is up

(display text omitted)

Encapsulation ARPA, loopback not set, keepalive not set, hdx, MII

(display text omitted)

Use the media-type 100BaseX command to return the media type to the RJ-45 receptacle.
