Configuring port operating parameters

Autonegotiation is enabled by default on a WSS’s 10/100 Ethernet ports and gigabit Ethernet ports.
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. All ports on the 2380 switches support full-duplex operating mode only. They do
not support half-duplex operation. The 10/100 ports on the 2360/2361 or 2382 switches
support half-duplex and full-duplex operation.
Note. 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.
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.
Note. WSS Software 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.
