Configuring availability using the availability wizard

If the Poll Timeout value is less than 1.5 to 2 times of Detect link failure
value, the Wireless AP failover will not succeed because the secondary
controller will not be 'ready' to accept the failover APs.
On the other hand, if the Poll Timeout value is more than 1.5 to 2 times of
Detect link failure value, the Wireless APs failover will be unnecessarily
delayed, because the Wireless APs will continue polling the primary controller
even though the secondary controller is ready to accept them as the failover
APs.
To achieve ideal 'availability' behavior, you must set the Poll Timeout value
for all Wireless APs to 15 seconds, and the Detect link failure on the HiPath
Wireless Controller > Availability screen to ten seconds.
7.2 Configuring availability using the availability wizard
The availability wizard allows you to create an availability pair from one of the
HiPath Wireless Controller’s that will take part in the availability pair. When
creating the availability pair, you also have the option to synchronize VNS
definitions and GuestPortal user accounts between the paired HiPath Wireless
Controllers.
To configure availability using the availability wizard:
1. From the main menu, click Wireless Controller Configuration. The HiPath
Wireless Controller Configuration screen is displayed.
2. In the left pane, click Availability. The availability configuration screen is
displayed.
3. In the Availability Wizard section, click Start. The Availability Pair Wizard
screen is displayed.
