Configuring the Interfaces
Configuring FE Port Adapter Transmission Mode
Depending on the requirements for your system configuration and the protocols you plan to route on the
interface, you might also need to enter other configuration subcommands. For complete descriptions of
configuration subcommands and the configuration options available for Fast Ethernet interfaces, refer to
the publications listed in the
Following are descriptions and examples of the commands for configuring the PA-2FEISL interface 4/0
Note
(slot 4, Fast Ethernet interface port 0). Descriptions are limited to fields that are relevant for establishing
and verifying the configuration. After configuring a new PA-2FEISL interface, use show commands to
display the status of the new interface or all interfaces, or to verify changes you have made.
Half-duplex operation is the default for the PA-2FEISL. To change to full-duplex operation, use the
following series of commands:
Router# configure terminal
Enter configuration commands, one per line.
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
(display text omitted)
Use the no full-duplex configuration command to return the interface to half-duplex operation as
follows:
Router# configure terminal
Enter configuration commands, one per line.
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)
This completes the procedure for creating a basic configuration. To check the interface configuration
using show commands, proceed to the following section,
