3Com WX2200 3CRWX220095A Switch User Manual

To set the port speed on ports 1 and 3 through 5 to 10 Mbps, type the
following command:
WX1200# set port speed 1,3-5 10
Gigabit Ports — Autonegotiation and Flow Control
WX 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 a WX gigabit port, use the
following command:
set port negotiation port-list {enable | disable}
Disabling or Reenabling a Port
All ports are enabled by default. To administratively disable a port, use the
following command:
set port {enable | disable} port-list
A port that is administratively disabled cannot send or receive packets.
This command does not affect the link state of the port.
Disabling or Reenabling Power over Ethernet
Power over Ethernet (PoE) supplies DC power to a device connected to a
MAP access port. The PoE state depends on whether you enable or
disable PoE when you set the port type. (See “Setting the Port Type” on
page 71.)
CAUTION: Use the WX switch’s PoE only to power 3Com MAPs. If you
enable PoE on ports connected to other devices, damage can result.
PoE is supported only on 10/100 Ethernet ports. PoE is not supported on
any gigabit Ethernet ports, or on ports 7 and 8 on a WX1200 switch.
To change the PoE state on a port, use the following command:
set ap <apnum> port <portnumb> model <ap_type> poe {enable |
