34 Second-Generation Fast Ethernet Interface Processor (FEIP2) Installation and Configuration
Configuring the Fast Ethernet Interfaces
Using the show interfaces fastethernet command, you can see that the 3/0/0 FE interface is now
configured for full-duplex operation:
Router# sh int fa 3/0/0
FastEthernet 3/0/0 is administratively up, line protocol is up
(display text omitted)
Encapsulation ARPA, loopback not set, keepalive not set, fdx, 100BaseTX
To return the interface to half-duplex operation, use the no full-duplex configuration command, as
follows:
Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# int fa 3/0/0
Router(config-if)# no full-duplex
Ctrl-z
Router#
Using the show interfaces fastethernet command, you can see that the 3/0/0 FE interface is now
configured for half-duplex operation:
Router# sh int fa 3/0/0
FastEthernet3/0/0 is administratively up, line protocol is up
(display text omitted)
Encapsulation ARPA, loopback not set, keepalive not set, hdx, 100BaseTX
(display text omitted)
The RJ-45 connection is the default for FEIP2-2TX (or SC for FEIP2-2FX). To change to an MII
connection and then verify it, use the following series of commands, including the media-type
configuration command:
Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# int fa 3/0/0
Router(config-if)# media-type mii
Ctrl-z
Router# sh int fa 3/0/0
FastEthernet3/0/0 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 100 configuration command to return the interface to its default state for RJ-45
or SC (fiber-optic) connections.
