Availability, mobility, and controller functionality
Summit WM Series WLAN Switch and Altitude Access Point Software Version 4.1 User Guide
160
● Defines the registration behavior for a multi-controller mobility domain set:
● Open mode – A new agent is automatically able to register itself with the mobility manager and
immediately becomes part of the mobility domain
● Secure mode – The mobility manager does not allow a new agent to automatically register.
Instead, the connection with the new agent is placed in pending state until the administrator
approves the new device.
● Listens for connection attempts from mobility agents
● Establishes connection and sends a message to the mobility agent specifying the Heartbeat interval,
and the mobility manager's IP address if it receives a connection attempt from the agent
● Sends regular Heartbeat messages containing wireless device session changes and agent changes to
the mobility agents and waits for a returned update message
The Summit WM series switch designated as a mobility agent:
● Uses SLP or a statically configured IP address to locate the mobility manager
● Defines at the agent the IP address of the mobility manager, which allows for the bypass of SLP.
Agents directly find and attempt to register with the mobility manager.
● Attempts to establish a TCP/IP connection with the mobility manager
● Updates its tables, and sets up data tunnels to and between all Summit WM series switches it has
been informed of when it receives the connection-established message
● Uses the information from every Heartbeat message received to update its own tables and updates
the mobility manager with information on the wireless device users and data tunnels it is managing
If a controller configured as the mobility manager is lost, the following occurs:
● Agent to agent connections will remain active.
● Mobility agents will continue to operate based on the mobility information last coordinated before
the manager link was lost. The mobility location list remains relatively unaffected by the controller
failure. Only entries associated with the failed controller are cleared from the registration list, and
users that have roamed from the manager controller to other agents are terminated and required to
re-register as local users with the agent where they are currently located.
● Participant controllers are reset to nodal operation
● Any user sessions that roamed away from their home AP are terminated and must reconnect
● Users need to reconnect to network, re-authenticate, and obtain new IP address
● The data link between active controllers remains active after the loss of a mobility manager
● Mobility agents continue to use the last set of mobility location list to service known users
● Existing users:
● Existing users remain in mobility scenario, and if the users are known to mobility domain, they
continue to be able to roam between connected controllers
● New users:
● New users become local at attaching controller
● Roaming to another controller resets session
