duplex
If the speed is set to auto, the switch negotiates with the device at the other end of the link for the speed
setting and then forces the speed setting to the negotiated value. The duplex setting remains as
configured on each end of the link, which could result in a duplex setting mismatch.
You can configure the duplex setting when the speed is set to auto.
Caution Changing the interface speed and duplex mode configuration might shut down and re-enable the
interface during the reconfiguration.
For guidelines on setting the switch speed and duplex parameters, see the “Configuring Interface
Characteristics” chapter in the software configuration guide for this release.
Examples This example shows how to configure an interface for full-duplex operation:
Switch(config)# interface gigabitethernet1/0/17
Switch(config-if)# duplex full
You can verify your setting by entering the show interfaces privileged EXEC command.
