Create a new HA Group.
Enter a name for the HA group.
(Optional)
Enter description and tags.
Check the
Preempt?
check box, to enable preemption.
If Preempt is enabled, it dictates that a re-election within the group should be forced whenever there is a priority change that results in the current active device’s priority to be less than that of the backup device. If disabled, it will dictate that an election not happen as long as the current active device has not experienced a catastrophic failure, which causes the priority to immediately go to 0 (e.g. power loss, critical process failure, loss of link on the HA control port, or track events which cause the priority to reduce to 0), even if the backup device has a higher priority.
Enter an
Advertisement Interval
between 1 and 10 seconds.
The Advertisement Interval indicates how often the active device advertises its status to the backup. Three consecutive missed advertisements indicate that the active device has failed after which a backup device becomes active and takes over as the active device. The value recommended for Advertisement Interval is 1 second.
Click
Create
.
An Up arrow indicates that the device is enabled for Branch HA. After an HA group is created, the Redundancy section shows the option to assign and configure devices in the HA group.
