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.
6.2.5 Setting Speed on the Ethernet Port
You can use the following command to set the speed on the Ethernet port. If the speed
is set to auto-negotiation mode, the local and peer ports will automatically negotiate
about the port speed.
Perform the following configuration in Ethernet port view.

Note that, the 10/100 Mbps electrical Ethernet port can operate at 10 Mbps, 100 Mbps
and in auto mode. You can set it accordingly. The 10/100/1000Mbps electrical Ethernet
port can operate at 10 Mbps, 100 Mbps, or 1000 Mbps as per different requirements.
However in half duplex mode, the port cannot operate at 1000 Mbps or in auto mode.
The 100 Mbps optical Ethernet port supports 100 Mbps; the 1000 Mbps optical
Ethernet port supports 1000 Mbps; the 10 Gbps optical Ethernet port supports 10 Gbps
without user intervention.
By default, the speed of the port is in auto mode.
6.2.6 Setting the Cable Type for the Ethernet Port
The Ethernet port supports the straight-through and cross-over network cables. The
following command can be used for configuring the cable type.
Perform the following configuration in Ethernet port view.
