Book Title
SUMMARY STEPS
1. enable
2. configure terminal
3. interface fastethernet interface-id
4. duplex [auto | full | half]
DETAILED STEPS
Note If you set the port speed to auto on a 10/100-Mbps Ethernet interface, both speed and duplex are
automatically negotiated. You cannot change the duplex mode of auto negotiation interfaces.
The following example shows how to set the interface duplex mode to auto on Fast Ethernet interface 3:
Router(config)# interface fastethernet 0/1/0
Router(config-if)# speed 100
Router(config-if)# duplex auto
Router(config-if)# end
Verifying Interface Speed and Duplex Mode Configuration
Use the show interfaces command to verify the interface speed and duplex mode configuration for an
interface, as shown in the following output example.
Router# show interfaces fastethernet 0/1/0
FastEthernet0/1/0 is up, line protocol is up
Hardware is Fast Ethernet, address is 000f.f70a.f272 (bia 000f.f70a.f272)
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Command or Action Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
interface fastethernet interface-id
Example:
Router(config)# interface fastethernet 0/1/0
Selects the interface to be configured.
Step 4
duplex [auto | full | half]
Example:
Router(config-if)# duplex auto
Sets the duplex mode of the interface.
