HiPath Wireless Controller, Access Points and Convergence Software V7.11, User Guide 395
1. Monitor the critical messages for the failover mode message, in the
information log of the secondary HiPath Wireless Controller (in the Logs &
Traces section of the HiPath Wireless Assistant).
2. After recovery, on the secondary HiPath Wireless Controller, select the
foreign Wireless APs, and then click Release on the Access Approval
screen.
After the Wireless APs are released, they establish the active tunnel to their home
controller and backup tunnel to the secondary controller.
7.4.2 Enabling session availability
Starting with V7.0, session availability is supported when fast failover is enabled
and when “Synchronize System Configuration” is selected. For more information,
see Section 7.4.2.1, “Configuring fast failover and enabling session availability”,
on page 395.
In session availability, mobile user devices are able to retain their IP address. In
addition, the mobile user device does not have to have to re-associate after the
failover. These characteristics ensure that the failover is achieved within 5
seconds, which is fast enough to maintain the mobile user’s session.
Note: In session availability, the fast failover is achieved within 5 seconds only if
there is at least one client device (mobile unit) associated to the Wireless AP. In
the absence of any client device, the Wireless AP takes more time to failover
since there is no need to preserve the user session.
Authentication state during failover
The authentication state is not preserved during fast failover. If a WLAN Service
requires authentication, the client device must re-authenticate. However, in such
a case, the session availability is not guaranteed because authentication may
require additional time during which the user session may be disrupted.
Session availability is not supported in a WLAN Service that uses Captive Portal
(CP) authentication.
Session availability does not support user-specific filters as these filters are not
shared between the primary and secondary HiPath Wireless Controllers.
7.4.2.1 Configuring fast failover and enabling session
availability
Before you configure the fast failover feature, you must ensure:
