Enabling/Disabling an
Ethernet Port
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.
Setting Ethernet Port
Description
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.
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 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.
