Release Notes

Parameter Description Range Default
preempt
Preempt mode allows a
controller to take over the role of
master if it detects a lower
priority controller currently acting
as master.
Best practices are to use the
default value to avoid excessive
interruption to users or “flapping”
if a problematic controller is
cycling up and down.
— disabled
delay
Delay value in seconds.
Specifying a value enables the
delay timer. The timer is
triggered when the VRRP state
moves out of backup or init state
to become a master. This is
applicable only if router pre-
emption is enabled.
When the timer is triggered, it
delays the router for a specified
period of time before taking over
the master router. In the mean
time, if there is an advertisement
from another VRRP master
(existing master), the router
stops the timer and does not
transition to master.
0-60
seconds
0
priority
Defines the priority level of the
VRRP instance for the controller.
This value is used in the election
mechanism for the master.
A higher number specifies a
higher priority.
The default priority setting is
adequate for most networks.
100 1-255
shutdown
Administratively shutdown VRRP.
When down, VRRP is not active,
although the controller maintains
the configuration information.
To start the VRRP instance, use
no shutdown.
— enabled
(VRRP is
down)
tracking interface
Configures VRRP tracking based
on Layer-2 interface state
transitions. You can configure
this on Fast Ethernet or Gigabit
Ethernet interfaces.
You can track a combined
maximum of 16 VLAN and Layer-
2 interfaces.

<slot>
<slot> is always 1. — —
<port>
