Configuring Mobility Domain - Extreme Networks Summit WM User Manual

Mobility
If the failover takes place, and the user is still associated with Wireless AP1:
The Wireless AP 1 fails over, and establishes active session with WM2.
In response to the heart beat message from the mobility manager (WM3), the WM2 sends updates
to the mobility manager on the failover Wireless AP and its user.
If the failover takes place, and the user has roamed to Wireless AP 2:
As part of roaming, the user's home session moves from WM1 to WM2.
Wireless AP 1 establishes active session with WM 2. Wireless AP 2 is not impacted by the failover.
NOTE
The mobility feature is not backward compatible. This means that all the Summit WM Controllers in the mobility
domain must be running Summit WM Software V5R3 release.
