configure terminal
interface Ethernet <port> or interface vlan <1–4094>
2. At the command prompt, enter the following command:
[default] duplex [port <portlist>] {full|half|auto}
Variable definitions
The following table describes the parameters for the duplex [port <portlist>] command.
Variable Value
port<portlist> Specifies the port number to configure the duplex
mode. Enter the port number you want to configure,
or ALL to configure all ports simultaneously.
Important:
If you omit this parameter, the system uses the
port number you specified in the interface
command.
full|half|auto Sets duplex to:
• full — full-duplex mode
• half — half-duplex mode
• auto — autonegotiation
Important:
When you set the duplex mode for
autonegotiation, ensure that the other side of
the link is also set for autonegotiation.
default Sets the duplex operation for a port to the factory
default duplex value.
High speed flow control
The high speed flow control feature lets you control traffic and avoid congestion on the gigabit full-
duplex link. If the receive port buffer becomes full, the switch issues a flow-control signal to the
device at the other end of the link to suspend transmission. When the receive buffer is no longer full,
the switch issues a signal to resume the transmission. You can set the flow control mode to
Asymmetric or disabled.
