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
only transmit packets at one time.
Usage guidelines
Fiber ports do not support the half keyword.
Examples
# Configure interface Ten-GigabitEthernet 1/0/1 to operate in full duplex mode.

Usage guidelines
To implement flow control on a link, enable the generic flow control function at both ends of the link.
TxRx mode generic flow control enables an Ethernet interface to receive common pause frames from its
peer, and send common pause frames to notify its peer of congestions.
With the flow-control command configured, an interface can both send and receive flow control frames:
When congested, the interface sends a flow control frame to its peer.
Upon receiving a flow control frame from the peer, the interface suspends sending packets.
