Setting the Duplex Attribute of the Ethernet Port
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, set it to
half-duplex. If the port has been set to auto-negotiation mode, the local and peer
ports will automatically negotiate the duplex mode.
Perform the following configuration in Ethernet Port View.

Note that the 10/100/1000BASE-T port can operate in full duplex, half duplex or
auto-negotiation mode. When the port operates at 1000Mbps, the duplex mode
can be set to full (full duplex) or auto (auto-negotiation). The Gigabit ports and
10G port support full duplex mode and can be configured to operate in full (full
duplex) or auto (auto-negotiation) mode.
The port defaults to auto (auto-negotiation) mode.
Setting Speed on the Ethernet Port
Use the following command to set the speed of the Ethernet port. If the speed is
set to auto-negotiation mode, the local and peer ports will automatically negotiate
the port speed.
Perform the following configuration in Ethernet Port View.

Note that the 10/100/1000BASE-T ports, excluding the combo ports, can operate
at 10Mbps, 100Mbps or 1000Mbps as per different requirements. However, in
half duplex mode, the port cannot operate at 1000Mbps. The Gigabit Ethernet
port supports 1000Mbps and can be configured to operate at 1000 (1000Mbps)
and auto (auto-negotiation).
By default, the speed of the port set to auto mode.
