Usage Guidelines Use this interface configuration command to configure an interface for half duplex. Full duplex allows
data to travel in both directions at the same time through an interface or a cable. Half duplex ensures that
data travels only in one direction at any given time. Although full duplex is faster, the interfaces
sometimes cannot operate effectively in this mode. If you encounter excessive collisions or network
errors, configure the interface for half duplex rather than full duplex.
Note We strongly recommend that you do not use half duplex on the WAE, routers, switches, or other
devices. Half duplex impedes the system ability to improve performance and should not be used.
Check each Cisco WAE interface and the port configuration on the adjacent device (router,
switch, firewall, WAE) to verify that full duplex is configured.
Examples The following example shows how to configure half duplex on the Gigabit Ethernet interface in
slot 1/port 0:
WAE# configure
WAE(config)# interface GigabitEthernet 1/0
WAE(config-if)# half-duplex
The following example shows how to disable half duplex:
WAE(config-if)# no half-duplex
