Configuring the Catalyst 3750G Integrated Wireless LAN Controller Switch
You can also configure other parameters on these ports in interface configuration mode. For example, by
default, all traffic on all VLANs are sent to the controller. You should limit the VLANs that are allowed
on the internal trunk by using the switchport trunk allowed vlan interface configuration command. You
enter interface configuration mode for an internal port the same as any other port. For example, if the
wireless LAN controller switch is a standalone switch or switch number 1 in a stack, use this command
to enter interface configuration mode for internal port 27:
Switch(config)# gigabitethernet1/0/27
Switch(config-if)#
The internal ports are automatically configured to belong to a static Ether Channel that has PAgP and
LACP disabled. No other ports (internal or otherwise) in the switch stack should be members of this
EtherChannel. To identify the internal port channel number that the switch has automatically configured,
use the show etherchannel summary privileged EXEC command.
This output shows that the internal ports on switch 1 in the stack belong to port channel 40. You should
not use this port channel for any other ports in the stack.

Reconfiguring the Internal Ports
You should not modify the automatic configuration of the internal ports, but if they somehow lose the
automatic configuration, you should reconfigure the ports to that configuration.
Beginning in privileged EXEC mode, follow these steps to configure the internal ports to the automatic
configuration:

Purpose
Enter global configuration mode.
Specify one of the internal ports, and enter interface configuration
mode. The internal ports are gigabitethernet switch-number/0/27 and
gigabitethernet switch-number/0/28.
