Configuring Availability Using the Availability Wizard

The availability wizard allows you to create an availability pair from one of the controllers that will be in the availability pair. When creating the availability pair, you also have the option to synchronize VNS definitions and GuestPortal user accounts between the paired controllers.

To Configure Availability Using the Availability Wizard:

  1. From the top menu, click Controller.
  2. In the left pane, click Administration > Availability.
  3. In the Availability Wizard section, click Start.
    The Availability Pair Wizard screen displays.
    Click to expand in new window

  4. In the Connection Details section, do the following:
    • Select Port — Select the port and IP address of the primary controller that is to be used to establish the availability link.
    • Peer Controller IP — Type the IP address of the peer (secondary) controller.
    • User — Type the login user name credentials of an account that has full administrative privileges on the peer controller.
    • Password — Type the login password used with the user ID to login to the peer controller.
    • Enable Fast Failover — Select this checkbox to enable Fast Failover for the availability pair.
  5. In the Synchronize Options section, do the following:
    • Synchronize System Configuration — Select this checkbox to push the configured Routed and Bridge Traffic Locally at Controller VNS definitions from the primary controller to the peer controller. WDS and 3rd Party AP VNS definitions are ignored and not synchronized.
      Note

      Note

      Synchronizing the VNS definitions will delete and replace existing VNS definitions on the peer controller.
    • Synchronize Guest Portal Accounts — Select this checkbox to push GuestPortal user accounts to the peer controller.
  6. Click Next.
  7. If you are synchronizing topology definitions, the Topology Definitions screen displays. Do the following:
    1. In the Synchronization Settings section, complete the topology properties that are missing. Any topology that did not already exist on the peer controller will have missing properties on the Topology Definitions screen.

      The fields configured are actual parameter values that are configured at the remote Controller with respect to associated topologies chosen for synchronization. Some of these parameters are: Interface IP address, Netmask, L2 port, VLAN ID, DHCP (Dynamic Host Configuration Protocol) range, etc.

    2. Click Finish.
  8. If you are not synchronizing topology definitions, the availability wizard completes the configuration.
  9. Click Close.

This operation marks the desired topologies for synchronization. The two controllers exchange information and the configuration is applied to the remote controller.

On the local controller, the “Enable Synchronization of System Configuration” becomes selected. This can be double checked by navigating to VNS > Global > Sync Summary. This tab also lists all topologies, roles, WLAN Services and VNSes with their synchronization status (on or off).

The Sync status for any of these elements can also be changed from this tab.

All these configurable elements have a Synchronize check box (on their main/general configuration tab) that allows for individual control and selection of availability from the main element configuration page.
