Configuring PA-FE Transmission Mode
Half-duplex operation is the default transmission mode for the PA-FE. Use the full-duplex
command to configure full-duplex operation for the PA-FE as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Router(config)# interface fastethernet 4/0
Router(config-if)# full-duplex
Ctrl-z
Use the show interfaces fastethernet command to verify that the 4/0 Fast Ethernet interface is now
configured for full-duplex operation as follows:
Router# show interfaces fastethernet 4/0
FastEthernet 4/0 is administratively up, line protocol is up
(display text omitted)
Encapsulation ARPA, loopback not set, keepalive not set, fdx, 100BaseTX
Use the no full-duplex command to return the interface to half-duplex operation as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface fastethernet 4/0
Router(config-if)# no full-duplex
Ctrl-z
Router#
Use the show interfaces fastethernet command to verify that the 4/0 Fast Ethernet interface is now
configured for half-duplex operation as follows:
Router# show interfaces fastethernet 4/0
FastEthernet2/0 is administratively up, line protocol is up
(display text omitted)
Encapsulation ARPA, loopback not set, keepalive not set, hdx, 100BaseTX
(display text omitted)To check the interface configuration using show commands,
proceed to the “Checking the Configuration” section on page 8-9.
To check the interface configuration using show commands, proceed to the “Checking the
Configuration” section on page 8-9.
Configuring PA-FE Media Type
The RJ-45 receptacle is the default media type for PA-FE-TX and the SC receptacle (for fiber-optic
connections) is the default media type for the PA-FE-FX. Use the media-type mii command to
configure the MII receptacle as the media type for the PA-FE as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface fastethernet 4/0
Router(config-if)# media-type mii
Ctrl-z
Router# show interface fastethernet 4/0
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 command to return the media type for the PA-FE’s to the RJ-45 receptacle
or SC receptacle.
