ONFIGURATION

After configuring the related parameters and protocol of the port, you can use 
undo shutdown command to enable the port. If you do not want a port to 
forward data any more, use shutdown command to disable it.

Perform the following configuration in Ethernet port view.

By default, the port is enabled.

To distinguish the Ethernet ports, you can use the following command to make 
some necessary descriptions.

Perform the following configuration in Ethernet port view.

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.
