Configuring the 12E/2FE Interfaces
PA-12E/2FE Ethernet Switch 10BASE-T and 100BASE-TX Port Adapter Installation and Configuration
6-10
The first example below shows the first 12E/2FE interface port (interface port 0) in port adapter
slot 3 is autosensing and autonegotiating the transmission mode with an attached device; the second
example shows the same interface configured for half-duplex mode:
Router# show running-config
(display text omitted)
interface FastEthernet3/0
no ip address
bridge-group 1
(display text omitted)
Router# show running-config
(display text omitted)
interface FastEthernet3/0
no ip address
half-duplex
bridge-group 1
(display text omitted)
Use the full-duplex and half-duplex commands to change the transmission mode of a 12E/2FE
interface. After changing the transmission mode, use the show interfaces command to verify the
interface’s transmission mode.
Note If you use the full-duplex and half-duplex commands to change the transmission mode of
the first two 12E/2FE interfaces (port 0 and port 1), the transmission speed of the two 12E/2FE
interfaces automatically defaults to 100 Mbps. The first two 12E/2FE interfaces only operate at
10 Mbps when the interfaces are autosensing and autonegotiating the proper connection speed
(10 Mbps or 100 Mbps) with an attached device.
In the following example, full-duplex mode is configured on the first 12E/2FE interface port
(interface port 0) in port adapter slot 3:
Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface fastethernet 3/0
Router(config-if)# full-duplex
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet3/0, changed
state to up
%LINK-3-UPDOWN: Interface FastEthernet3/0, changed state to up
Router# sh interface fastethernet 3/0
FastEthernet0/0 is administratively up, line protocol is up
