Preventing WAN Link Failure on Virtual APs

In managed device deployments, the managed devices are connected across the WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. link from the Mobility Master to the RADIUSRemote Authentication Dial-In User Service. An Industry-standard network access protocol for remote authentication. It allows authentication, authorization, and accounting of remote users who want to access network resources.  server. A WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. link outage will result in service outage as new users cannot be authenticated to 802.1X802.1X is an IEEE standard for port-based network access control designed to enhance 802.11 WLAN security. 802.1X provides an authentication framework that allows a user to be authenticated by a central authority. Virtual APs. This feature provides limited connectivity to managed devices even when the WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. link is down. To provide connectivity when the WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. link is down, open and PSKPre-shared key. A unique shared secret that was previously shared between two parties by using a secure channel. This is used with WPA security, which requires the owner of a network to provide a passphrase to users for network access. SSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network. Virtual APs are available at all times and the user can connect to these Virtual APs instead of the main 802.1X802.1X is an IEEE standard for port-based network access control designed to enhance 802.11 WLAN security. 802.1X provides an authentication framework that allows a user to be authenticated by a central authority. Virtual AP.

 

Currently, this feature is targeted for Campus APsCampus APs are used in private networks where APs connect over private links (LAN, WLAN, WAN or MPLS) and terminate directly on controllers. Campus APs are deployed as part of the indoor campus solution in enterprise office buildings, warehouses, hospitals, universities, and so on. in managed device deployments.

When all the WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. 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 Virtual APs for WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. link failure feature can be configured using the Mobility Master WebUI or command-line interface.

To prevent the WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. link failure on virtual APs using the WebUI, complete the following steps:

1. In the Managed Network node hierarchy, navigate to the Configuration> System> Profiles tab.

2. In the All Profiles pane, expand the Wireless LAN menu.

3. Expand the Virtual AP menu.

4. Select an existing virtual AP profile.

5. Expand the Advanced accordion.

6. The WAN Operation Mode drop-down list supports the primary, always, and backup WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. modes. To enable WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. link failure, set this mode to backup.

7. Click Submit.

8. Click Pending Changes.

9. In the Pending Changes window, select the check box and click Deploy Changes.
