interfaces duplex
Configures duplex mode. In full duplex mode, the interface transmits and receives data simultaneously. In 
half duplex mode, the interface can transmit or receive data at a given time. Auto duplex setting causes the 
switch to advertise all available duplex modes (half/full/both) for the port during autonegotiation.
interfaces slot[/port[-port2]] duplex {full | half | auto}
Syntax Definitions
slot
Slot number you want to configure.
port
Port number of the interface you want to configure.
port2
Last port number in a range of ports you want to configure.
full
Sets interface to full duplex mode.
half
Sets interface to half duplex mode.
auto
Switch will automatically set both the duplex mode settings to auto-
negotiation.
Defaults
Platforms Supported
OmniSwitch 6400, 6850, 6855, 9000, 9000E
Usage Guidelines
• You can only configure one slot at a time. Repeat the command to configure additional slots.
• Half duplex mode is not supported on Gigabit modules if a port is detected as Gigabit (1000 Mbps).
• OS9-GNI-C24 modules can be configured for full and half duplex. All other Gigabit Ethernet modules 
on the OmniSwitch 9000 only support full duplex mode.
• On OS9-GNI-C24 modules, if a link is down and auto negotiation is enabled, then half duplex is not 
accepted since these modules are Gigabit modules by default.
• Configuration changes made with the interfaces duplex command on combo ports configured as either 
forced copper or preferred copper will only be made on the copper RJ-45 10/100/1000 ports and not to 
the SFP fiber port. See the 
 command for more information.
• Gigabit and 10 Gigabit fiber ports only support full duplex.
