passwords.
You must configure all switches in the same virtual
router with the same password.
portmonitoring Specifies whether the VRRP should monitor the ports
of the VLAN and alter the priority value if ports fail or
are disabled. The options are:
on Specifies that port monitoring should be
on. If you choose not to specify a
stepvalue, the stepvalue is set to
proportional by default.
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 range is 1 to 254 and the default is
100. The value of 255 is reserved for and assigned to
the switch that is the preferred master (the switch
owning the virtual router’s IP address), regardless of
how this parameter is set.
