Chapter 19 Configuring Repeater and Standby Access Points and Workgroup Bridge Mode
Workgroup Bridge VLAN Tagging
The following example shows how the command is used. In the example, channels 1, 6, and 11 are
specified to scan:
ap#
ap#confure terminal
Enter configuration commands, one per line. End with CNTL/Z.
ap(config)#int d0
ap(config-if)#ssid limited_scan
ap(config-if)#station-role workgroup-bridge
ap(config-if)#mobile station
ap(config-if)#mobile station scan 1 6 11
ap(config-if)#end
ap#
Use the no mobile station scan command to restore scanning to all the channels.
Ignoring the CCX Neighbor List
In addition, the workgroup bridge updates its known channel list using CCX reports such as the AP
Adjacent report or Enhanced Neighbor List report. However, when a workgroup bridge is configured for
limited channel scanning, it does not need to process the CCX reports to update its known channel list.
Use the mobile station ignore neighbor-list command to disable processing of CCX neighbor list
reports. This command is effective only if the workgroup bridge is configured for limited scanning
channel scanning. The following example shows how this command is used
ap#
ap#confure terminal
Enter configuration commands, one per line. End with CNTL/Z.
ap(config)#int d0
ap(config-if)#mobile station ignore neighbor-list
ap(config-if)#end
Configuring a Client VLAN
If the devices connected to the workgroup bridge’s Ethernet port should all be assigned to a particular
VLAN, you can configure a VLAN for the connected devices. Enter this command on the workgroup
bridge:
ap(config)# workgroup-bridge client-vlan vlan-id
All the devices connected to the workgroup bridge’s Ethernet port are assigned to that VLAN.
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.
