A Cisco WGB device does not support multiple VLANs in it. A 1100 AP, however, that acts in WBG mode can support multiple VLANs in it but with these restrictions:
- The VLANs must be assigned on both the root AP and WGB sides. On WGB use the command workgroup-bridge client-vlan to configure the VLANs. On WGB make sure you map each VLAN to an SSID same as the Root AP.
- The WGB must be connected to a dot1Q-capable switch.
- The WGB associates as an infrastructure device. The Infrastructure SSID must be mapped to the native VLAN on root and the WGB.
