Mobility Domains Information

If more than one controller is being deployed, it is typically recommended that the inter-controller domain service be set up so as to facilitate ubiquitous roaming across the various APs on the infrastructure.

Even when the domain is restricted to two controllers in an availability pair, inter-controller mobility between the two controllers should correspondingly be enabled, especially when deploying services that rely on routed topologies.

A mobility domain is characterized by one of the controllers defined as the domain's manager and a set of mobility agents. The manager's role is to aggregate, consolidate and distribute the complete list of user-to-controller mapping so that any domain participant knows which controller may already own the session for a roaming user.

The manager may be configured to automatically accept any membership domain requests from agents or may be configured in restricted mode so that the administrator must explicitly approve the registration of a new controller into the mobility domain.

• Port – The interface of the ExtremeWireless Appliance that is to be used as the mobility manager. Verify that the selected interface is routable on the network.
• Heartbeat – The time interval (in seconds) at which the mobility manager sends a heartbeat message to the agent. The default is 5.

• Port – The interface of the ExtremeWireless Appliance that is to be used as the mobility agent. Verify that the selected interface is routable on the network.
• Heartbeat – The time interval (in seconds) for which the mobility agent waits for the connection establishment response before trying again. The default is 60.
• Discovery Method – The method by which the mobility agent will discover the mobility manager. You have two options:
  • SLPD (Service Location Protocol Daemon) – Enables the discovery of the mobility manager ExtremeWireless Appliance, using SLP. The mobility manager's address must be configured on the network using SLP when selecting this option.
  • Static Configuration – Allows the mobility agent to discover the mobility manager without the SLP support. If you select Static Configuration, use the IP address of the ExtremeWireless Appliance that serves as the mobility manager.
