Cisco Systems manual 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-duplexconfiguration 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-typeconfiguration 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.
