96 Configuring and managing ports and VLANsNN47250-500 (320657-F Version 02.01)Configuring port operating parametersAutonegotiation 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 stateYou 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 speedWSS 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 donot support half-duplex operation. The 10/100 ports on the 2360/2361 or 2382 switchessupport half-duplex and full-duplex operation.Note. Nortel recommends that you do not configure the mode of a WSS port so that oneside of the link is set to autonegotiation while the other side is set to full-duplex. AlthoughWSS Software allows this configuration, it can result in slow throughput on the link. Theslow throughput occurs because the side that is configured for autonegotiation falls back tohalf-duplex. A stream of large packets sent to a WSS port in such a configuration can causeforwarding 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 stopworking.
