Ethernet Port Overview 29
Perform the following configuration in Ethernet port view.
The Gigabit Ethernet Base-T ports can operate in full duplex, half duplex, or
auto-negotiation mode. When the ports operate at 1000 Mbps, the duplex mode
can be set to full (full duplex) or auto (auto-negotiation).
By default, the port is in auto (auto-negotiation) mode.
Setting the Speed of the Ethernet Port
You can use the following command to set the speed on the Ethernet port. If the
speed is set to auto (auto-negotiation) mode, the local and peer ports will
automatically negotiate the port speed.
Perform the following configuration in Ethernet port view.
The Gigabit Ethernet BASE-T port can operate at 10 Mbps, 100 Mbps, or 1000
Mbps. However in half duplex mode, the port cannot operate at 1000 Mbps. The
Gigabit optical Ethernet port supports1000 Mbps; the 10 Gigabit optical Ethernet
port supports 10000 Mbps, which does not need to be configured.
Setting the Cable Type for an Ethernet Port
The Ethernet port supports the straight-through (MDI) and cross-over (MDIX)
network cables. The Switch 8800 only supports auto (auto-sensing). If you set
some other type, you will see an error message. By default, the cable type is auto
(auto-recognized). The system will automatically recognize the type of cable
connecting to the port.
Perform the following configuration in Ethernet port view. The settings only take
effect on 10/100/1000 Mbps electrical ports.
Setting Flow Control for an Ethernet Port
If flow control is enabled on both the local and the peer switch and congestion
occurs in the local switch, the local switch can instruct its peer to temporarily stop
sending packets. Once the peer switch receives this message, it stops sending
