Workgroup Bridge VLAN
Tagging The Workgroup-Bridge (WGB) VLAN tagging feature enables segregation of
VLAN traffic based on the VLAN numbers for Unified WGB solution.
When this feature is enabled, the WGB removes the 802.1q header while sending
the packet from a VLAN client to the wireless LAN controller (WLC). WGB
gets the packet to a VLAN client without 802.1q header and WGB code has to
be modified to add the 802.1q header while forwarding the frame to the switch
behind WGB.
WGB updates the WLC with the wired-client VLAN information in the
Internet Access Point Protocol (IAPP) Association message. WLC treats the
WGB client as a VLAN-client and forwards the packet in the right VLAN
interface based on the source-mac-address.
In the upstream direction, WGB removes the 802.1q header from the packet
while sending to the WLC. In the downstream direction while forwarding the
packet to the switch connecting the wired-client, the WLC sends the packet to
WGB without the 802.1q tag and WGB adds a 4-byte 802.1q header based on
the destination mac-address.
For detailed information on VLANs, see Configuring VLANs on page 441 .

Configuring Workgroup
Bridge Mode Beginning in privileged EXEC mode, follow these steps to configure an access
point as a workgroup bridge:
1.
Enter global configuration mode.
configure terminal
2.
Enter interface configuration mode for the radio interface.
interface dot11radio {0 | 1}
3.
Set the radio role to workgroup bridge. If your access point contains two
radios, the radio not set to workgroup bridge mode is automatically
disabled.
station-role workgroup-bridge
4.
Create the SSID that the workgroup bridge uses to associate to a parent
access point or bridge.
ssid ssid-string
5.
Designate the SSID as an infrastructure SSID. The workgroup bridge
must use an infrastructure SSID to associate to a root access point or
bridge.
