virtual-dot11radio what for?

Hi Pat,

The Virtual-Dot11Radio interface is used to indicate whether or not there are any clients associated to a given access point or radio within that access point.

When clients are associated, the Virtual-Dot11Radio interface is up; when there are no clients associated, it shows down..

Use the infrastructure-client configuration interface command to configure a virtual interface for a workgroup bridge client.

Use the no form of the command to disable the workgroup bridge client virtual interface.

This is dynamically created when the AP is configured for infrastructure client mode.

When debugging the virtual interface the management traffics are not included.

If the native VLAN on the switchport is configured as VLAN 12 and on the AP, the native VLAN is configured as VLAN 1, then when the AP sends a frame on its native VLAN to the switch, the switch considers the frame as belonging to VLAN 12 since the frames from the native VLAN of the AP are untagged.

This causes confusion in the network and results in connectivity problems.

The same happens when the switchport forwards a frame from its native VLAN to the AP.

The configuration of native VLAN becomes even more important when you have a Repeater AP setup in your wireless network.

You cannot configure multiple VLANs on the Repeater APs. Repeater APs support only the native VLAN.

Therefore, the native VLAN configuration on the root AP, the switch port to which the AP is connected, and the Repeater AP, must be the same.

Otherwise traffic through the switch does not pass to and from the Repeater AP.

Hope this helps.
