Configuring Port Operating Parameters

Autonegotiation is enabled by default on an WSS switch’s 10/100 Ethernet ports and gigabit Ethernet ports.

Note. All ports on the WSS-2370 and WSS-2380 switches support full-duplex operating mode only. They do not support half-duplex operation. Ports on the WSS-2360 switch support half-duplex and full-duplex operation.

You can configure the following port operating parameters:

•Speed

•Autonegotiation

•Port state

•PoE state

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

WSS 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}

Note. 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.

To set the port speed on ports 1, 7 through 11, and 14 to 10 Mbps, type the following command:

23x0# set port speed 1,7-11,14 10

Gigabit Ports—Autonegotiation and Flow Control

WSS gigabit ports use autonegotiation by default to determine capabilities for 802.3z flow control parameters. The gigabit ports can respond to IEEE 802.3z flow control packets. Some devices use this capability to prevent packet loss by temporarily pausing data transmission.

To disable flow control negotiation on an WSS gigabit port, use the following command:

set port negotiation port-list{enable disable}

10/100 Ethernet Ports—Full-Duplex-Only Operation (WSS-2370 only)

WSS-2360 10/100 Ethernet ports support half-duplex and full-duplex operation.

WSS-2370 10/100 Ethernet ports do not support half-duplex operation. As a result, there are restrictions when WSS-20 10/100 Ethernet ports are interoperating with other vendors’ devices. For a link to occur, the autonegotiation settings on
