Configuring Ports
Step 3 Table 3-3 lists and describes the port’s configurable parameters. Follow the instructions in the table to
make any desired changes.
Power over Ethernet (PoE) Determines if the connecting device is equipped to receive power
through the Ethernet cable and if so provides -48 VDC.
Values: Enable or Disable
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).
Note The controller in the Catalyst 3750G Integrated Wireless LAN
Controller Switch supports PoE on all ports.
Table 3-3 Port Parameters
Parameter Description
Admin Status Enables or disables the flow of traffic through the port.
Options: Enable or Disable
Default: Enable
Note 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.
Physical Mode 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 Supported Data Rates
4400 series Auto or 1000 Mbps full duplex
2100 series Auto or 10 or 100 Mbps, half or
full duplex
WiSM Auto or 1000 Mbps full duplex
Controller network module Auto or 100 Mbps full duplex
Catalyst 3750G Integrated Wireless
LAN Controller Switch
Auto or 1000 Mbps full duplex
Note 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.
