Chapter 35: Virtual Router Redundancy Protocol (VRRP) Commands

610

Section II: Advanced Operations

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.

delay

Specifies the number of seconds that a higher priority
switch must wait before preempting a lower priority
switch. This parameter is only valid when the preempt
parameter is set to ON. After the switch assumes the
highest priority, it waits the delay time and then
assumes control. A delay ensures that there is
enough time for the master to update its routing
tables before taking over. The range is 0 to 3600 and
the default is 0 (off).

Description

This command creates a VRRP virtual router. If other VRRP virtual routers
have been created on the LAN with the same VRID, the combined group
forms a single virtual router.

Note

You must create the virtual router on at least two switches for VRRP
to operate correctly.

Note

All switches involved in a virtual router must be configured with the
same values for the VRID, IP ADDRESSS, ADINTERVAL,
PREEMPT, AUTHENTICATION and PASSWORD values in order to
operate properly.

Example

This example creates a virtual router with a VRID of 7, an IP address of
12.37.8.2 over VLAN2-0, with port monitoring enabled and a stepvalue of
45:

create vrrp=7 over=vlan2-0 ip=12.37.8.2 portmonitoring=on
stepvalue=45
