By default, an Ethernet port has no description.
To configure a port to send and receive data packets at the same time, set it to
full-duplex. To configure a port to either send or receive data packets at a time, set
it to half-duplex. If the port has been set to auto-negotiation mode, the local and
peer ports will automatically negotiate about the duplex mode.
Perform the following configuration in Ethernet port view.

Note that, 10/100 Mbps electrical Ethernet port can operate in full-duplex,
half-duplex or auto-negotiation mode. The10/100/1000 Mbps electrical Ethernet
port can operate in full duplex, half duplex or auto-negotiation mode. When the
port operates at 1000 Mbps or in auto mode, the duplex mode can be set to full
(full duplex) or auto (auto-negotiation). The optical 100/1000 Mbps and 10 Gbps
Ethernet ports work in full duplex mode without user intervention.
The port defaults the auto (auto-negotiation) mode.
