Parameters

auto: Configures the interface to autonegotiate the duplex mode with the peer.

full: Configures the interface to operate in full duplex mode, so that the interface can receive and transmit packets at the same time.

half: Configures the interface to operate in half duplex mode, so that the interface can only receive or transmit packets at a given time. Copper ports operating at 1000 Mbps or 10 Gbps and fiber ports do not support this keyword.

Examples

# Configure Ten-GigabitEthernet 1/0/1 to operate in full duplex mode.
