If you select Tagged, type the VLAN ID in the VLAN ID box.
NOTE
The VLAN IDs are assigned by the branch office network administrator. The AP will operate correctly if you set
the VLAN ID corresponding to the VLAN ID that was setup in the LAN.
Configuring two untagged branch WM-ADs to the same AP on different radios is permitted. This is similar to
having two untagged branch WM-ADs with the same VLAN ID assigned to the same AP on different radios. In
both cases, the AP will connect the two WM-ADs. That type of configuration can be viewed as a single WM-AD/
VLAN with different SSIDs on different radios.
An effective scenario of the configuration described above, in which the same subnet is used with different
SSIDs on radio a and b/g, is when this configuration is defined consistently on all APs. It would allow dual band
a+b/g clients to associate to one of the radios by specifying the correct SSID. This is particularly effective with
Microsoft clients that do not allow defining a preferred radio.

NOTE
In previous releases, an entire AP had to be put into branch mode. In the current release, an individual WM-AD
can be put into bridging mode. An AP can have bridged and non-bridged WM-ADs.
If it has more than one branch mode WM-AD, only one bridged WM-AD can be untagged per AP per radio. The
other branch mode WM-ADs need to have unique VLAN ID. You must have VLAN aware L2 switches to support
this feature.
NOTE
When a WM-AD is setup for bridged mode, it cannot be switched to tunneled mode. The administrator must
delete and re-add the WM-AD.
