Description
Enables or disables the flow of traffic through the port.

Default: Enable
Note
Determines whether the port's data rate is set automatically or specified
by the user. The supported data rates vary based on controller type.
Default: Auto

Controller network module
Catalyst 3750G Integrated Wireless
LAN Controller Switch
Note
Some older Cisco access points do not draw PoE even if it is
enabled on the controller port. In such cases, contact the Cisco
Technical Assistance Center (TAC).
The controller in the Catalyst 3750G Integrated Wireless LAN
Controller Switch supports PoE on all ports.
Administratively disabling the port on a controller does not
affect the port's link status. The link can be brought down only
by other Cisco devices. On other Cisco products, however,
administratively disabling a port brings the link down.
Make sure that a duplex mismatch does not exist between a
2100 series controller and the Catalyst switch. A duplex
mismatch is a situation where the switch operates at full duplex
and the connected device operates at half duplex or vice versa.
The results of a duplex mismatch are extremely slow
performance, intermittent connectivity, and loss of connection.
Other possible causes of data link errors at full duplex are bad
cables, faulty switch ports, or client software or hardware
issues.
