Ethernet Port Overview 37
Setting Duplex Attribute of the Ethernet Port
Set the port to full duplex to send and receive data packets at the same time. Set
the port to half-duplex to either send or receive only. 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.
The 100 Mbps TX Ethernet port can operate in full-duplex, half-duplex, or
auto-negotiation mode. The Gigabit TX Ethernet port can operate in full duplex,
half duplex, or auto-negotiation mode. When the port operates at 1000 Mbps,
the duplex mode can be set to full (full duplex) or auto (auto-negotiation).
The optical 100M/Gigabit/10Gigabit Ethernet ports support full duplex mode and
can be configured to operate in full (full duplex) or auto (auto-negotiation) mode.
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.
Setting Cable Type for Ethernet Port
The Ethernet port supports the straight-through (MDI) and cross-over (MDIX)
network cables. The Switch 7750 only supports auto (auto-sensing). If you set
another duplex type, an error message displays. 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 10/100BASE-T and 10/100/1000BASE-T ports.
