updates the mobility manager with information on the wireless device users and data
tunnels it is managing

Mobiltity agents will continue to operate based on the mobility information last coordinated
before the manager link was lost. The mobilility 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
