94 CHAPTER 4: PORT COMMANDS
Access — Enabled.
History — Introduced in MSS Version 3.0.
Usage — WX1200 10/100 Ethernet ports support half-duplex and
full-duplex operation.
3Com recommends that you do not configure the mode of an 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 an WX port in such a configuration can
cause forwarding on the link to stop.
Examples — The following command disables autonegotiation on ports
3 and 5:
WX1200# set port negotiation 3,5 disable
The following command enables autonegotiation on port 2:
WX1200# set port negotiation 2 enable
set port poe Enables or disables Power over Ethernet (PoE) on ports connected to MAP
access points.
CAUTION: When you set the port type for MAP use, you can enable PoE
on the port. Use the WX switch’s PoE to power 3Com MAP access points
only. If you enable PoE on ports connected to other devices, damage can
result.
Syntax —
set ap <apnum> port <portnum> model <ap_type> poe
enable | disable
enable — Enables PoE on the specified ports.
disable — Disables PoE on the specified ports.
Defaults — PoE is disabled on network and wired authentication ports.
The state on MAP access point ports depends on whether you enabled or
disabled PoE when setting the port type. See set port type ap on
page 97.
Access — Enabled.
