The priority value of the redundancy group.
This value is used in selecting the active
and standby peer.
The devices that belong to the same
redundancy group must be configured with a different
priority. The redundancy group with a highest
priority will become active unit during
negotiation phase of the redundancy.
If two (or more) devices in a group have
the same priority, the one with the highest IP address
of the interface is the active device.
If a redundancy group with high priority
value is online after its peer has become
active, then the group with high priority
will become standby. This behavior can be
changed by setting clrRedPreempt object to
'true'.
