Chapter 40: Virtual Router Redundancy Protocol (VRRP) Commands
784 Section VII: Internet Protocol Routing
off Specifies that port monitoring should be
off.This is the default.
portreset Specifies that ports of a VLAN that has a virtual router
be reset when a virtual router transitions from backup
to master status. The options are:
on Specifies that the VLAN ports be reset.
off Specifies that the VLAN ports are not
reset.
preempt Specifies whether a higher priority switch preempts a
lower priority switch acting as the master. The
preferred master (with a priority of 255) always
assumes the master role when it is available,
regardless of how this parameter is set. The options
are:
on Specifies that preempting should occur.
This is the default.
off Specifies that preempt mode not be
used.
You must configure all switches in the same virtual
router with the same preempt setting.
priority Specifies the switch’s priority for becoming the master
for the virtual router. The higher the value, the greater
the priority. The value of 255 is reserved for the
switch that is the preferred master (the switch owning
the virtual router’s IP address). The value of 255 is
always assigned to the preferred master, regardless
of how this parameter is set. The range is 1 to 254
and the default is 100.
stepvalue Specifies the value by which the priority of the virtual
router should be decremented each time a VLAN port
fails or is disabled when the portmonitoring parameter
is set to ON. The options are:
1...254 Specifies a value to decrement the
priority of the virtual router.
proportional Specifies that the virtual router reduces
the priority in proportion to the
percentage of available ports.
