Port Commands 49

set port negotiation

Disables or reenables autonegotiation on gigabit Ethernet or 10/100 Ethernet ports.

Syntax set port negotiation port-list{enable disable}

port-list	List of physical ports. WSS Software disables or reenables
	autonegotiation on all the specified ports.
enable	Enables autonegotiation on the specified ports.
disable	Disables autonegotiation on the specified ports.

Defaults Autonegotiation is enabled on all Ethernet ports by default. Access Enabled.

Usage The gigabit Ethernet ports operate at 1000 Mbps only. They do not change speed to match 10-Mbps or 100-Mbps links.

2382, 2360/2361 10/100 Ethernet ports support half-duplex and full-duplex operation.

Nortel recommends that you do not configure the mode of a WSS port so that one side of the link is set to autonegotiation while the other side is set to full-duplex. Although WSS Software 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 WSS port in such a configuration can cause forwarding on the link to stop.

Examples The following command disables autonegotiation on ports 3, 8, and 16 through 18:

WSS# set port negotiation 3,8,16-18 disable

The following command enables autonegotiation on port 21:

WSS# set port negotiation 21 enable

set port poe

Enables or disables Power over Ethernet (PoE) on ports connected to APs.

Caution! When you set the port type for AP use, you can enable PoE on the port. Use the WSS’s PoE to power Nortel APs only. If you enable PoE on ports connected to other devices, damage can result.

Syntax set port <portnum> poe {enabledisable}

port-list	List of physical ports. WSS Software disables or reenables PoE on all the
	specified ports.
enable	Enables PoE on the specified ports.
disable	Disables PoE on the specified ports.
