Configuring and Managing Ports

79

Configuring Port Autonegotiation is enabled by default on a WX switch’s 10/100 Ethernet Operating ports and gigabit Ethernet ports.

Parameters

You can configure the following port operating parameters:

„Speed

„Autonegotiation

„Port state

„PoE state

All ports on the WX4400 switches support full-duplex operating mode only. They do not support half-duplex operation. Ports on the WX1200 switch support half-duplex and full-duplex operation.

3Com recommends that you do not configure the mode of a WX port so that one side of the link is set to autonegotiation while the other side is set to full-duplex. Although MSS allows this configuration, it can result in slow throughput on the link. The slow throughput occurs because the side that is configured for autonegotiation falls back to half-duplex. A stream of large packets sent to a WX port in such a configuration can cause forwarding on the link to stop.

You also can toggle a port’s administrative state and PoE setting off and back on to reset the port.

10/100 Ports—Autonegotiation and Port Speed

WX 10/100 Ethernet ports use autonegotiation by default to determine the appropriate port speed.

To explicitly set the port speed of a 10/100 port, use the following command:

set port speed port-list{10 100 auto}

If you explicitly set the port speed (by selecting an option other than auto) of a 10/100 Ethernet port, the operating mode is set to full-duplex.

MSS allows the port speed of a gigabit port to be set to auto. However, this setting is invalid. If you set the port speed of a gigabit port to auto, the link will stop working.
