Syntax Description

Default

N/A.

Usage Guidelines

You must have administrator privileges to issue this command.

When the switch is active, you can issue this command to force the switch to become the backup device.

You can make the switch the backup for one particular VRRP class or for all currently conÞgured VRRP

classes. For each speciÞed class, the switchÕs preemption behavior for the class must be dont-preempt.

If this switch is already the backup for a speciÞed class, no addition action is required.

After the switch is made the backup for a speciÞed class, it can become active again following the

normal VRRP behavior. For example, the switch becomes active again if its VRRP peer is unavailable.

Example

The following command forces the switch to attempt to become the backup device for VRRP class 100.

configure vrrp vrid 100 force-slave
