NOTE
If the critical resource IP is defined, the resource needs to be checked for reach-ability whenever their is
heartbeat lost or APs may lose adoption.
NOTE
Redundancy uses UDP port 51515 for both source and destination port. The TCP connection uses 51515 as the
destination port, the source port is selected from the range of 32768 to 61000.
3 To enable Dynamic AP Load Balancing, check the Enable Dynamic AP Load Balancing option and define
the parameters below:
Runtime/Schedule
Start Date
Start Time
MU Threshold
Interval
4 Once Dynamic Load Balancing parameters are set, click the Dynamic AP LB Now button to run
Dynamic AP Load Balancing.
5 Managing clustering in the Web UI is done through the Cluster GUI feature. Check the Enable Cluster
GUI checkbox to enable this feature. The Cluster GUI feature updates many key screens in the Web
UI allowing you to see APs and MUs managed by all active members of a cluster.
6 Refer to the History field to view the current state of the redundancy group.

Check this box to enable the
minutes) for the controller to revert. Configure the interval between 1 and
1800 minutes. The default revert time is 5 minutes.
When a primary controller fails, the standby controller takes over APs
adopted by the primary. If the auto revert feature is enabled, when the
failed primary controller comes back up, the standby starts a timer based
on the auto-revert interval. At the expiry of auto-revert interval (if the
primary controller is still up), the standby controller releases all adopted
APs and goes back to a monitoring mode. The expiry timer either will be
stopped or restarted if the primary controller goes down and comes up
during the auto-revert interval.
Reverts an active fail-over standby controller to a passive standby
controller. When a user presses this button, the standby controller will
un-adopt all its adopted APs and move into a standby (passive) mode
only if all configured members are up again. The revert function does not
push APs to the primary controller unless the primary controller has failed
over.
Select Runtime or Schedule to determine when load balancing will run. If
Runtime is selected, load balancing will initiate anytime a new active
controller is added to the redundancy group. If Schedule is selected you
can configure a start date and time to execute load balancing. This
feature is not available when Dynamic Load Balancing is enabled.
If Schedule is selected as the load balancing mode, enter a start date for
load balancing to take place.
If Schedule is selected as the load balancing mode, enter a start time for
load balancing to take place.
The MU threshold specifies the number of minimum number of active
MUs on an AP to stop the AP from resetting for load balancing.
If Schedule is selected as the load balancing mode, enter an interval (in
days) for how often load balancing should take place. The valid range is
between 1 and 180 days.
