42 VIP-FE-TX/4E Installation and Configuration
VIP Port Adapter Functions
FE-TX half-duplex operation is the default. To change to full-duplex operation, use the following
series of commands:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Router(config)# interface fastethernet 3/0/0
Router(config-if)# full-duplex
Router(config-if)# ^z
Using the show interfaces fastethernet command, you can see that the 3/0/0 Fast Ethernet interface
is now configured for full-duplex operation, as follows:
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
Router(config-if)# ^Z
Router#
Using the show interfaces fastethernet command, you can see that the 3/0/0 Fast Ethernet interface
is now configured for half-duplex operation, as follows:
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. 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
Router(config-if)# ^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 100BaseTX configuration command to return the interface to its default state
for RJ-45 connections.
