323 | BranchController Config for Controllers Dell Networking W-Series ArubaOS 6.4.x| User Guide
When all the WAN links are down, an AP management module in the controller updates the link state using the
notification it receives from the health check manager. Depending on the link state, the new set of Virtual APs
are made available to the users, ensuring minimum service depending on the deployment. The VAPs for WAN
link failure feature can be configured using the branch controller WebUI or command-line interface.
In the WebUI
1. Access the WebUI of a W-7000 Series controller configured as a branch controller, and navigate to
Configuration> AP Configuration> AP Group Page.
2. Select an AP Group.
3. Navigate to Wireless LAN > Virtual AP.
4. Select an existing virtual AP or add a new virtual AP.
5. Once you select the virtual AP, click Advanced tab.
6. Modify the WAN OperationMode drop-down menu value to Primary, Always, or Backup. For WAN link
failure, this mode should be set to backup.
In the CLI
(host)(Virtual AP profile "default") #wan-operation backup
For example:
(host) (config) #wlan virtual-ap default
(host)(Virtual AP profile "default")#?
wan-operation Virtual-AP WAN operation
wmm-traffic-managemen.. WMM Traffic Management Profile
(host)(Virtual AP profile "default")#wan-operation ?
always Enable virtual-AP regardless of WAN link state.
backup Enable virtual-AP when WAN link is down.
primary Enable virtual-AP only when WAN link is present.
(host)(Virtual AP profile "default") #wan-operation backup
