Changing the backup priority
When you enter the backup command to configure the device as a VSRP backup for the VRID, you
also can change the backup priority and the track priority:
• The backup priority is used for election of the master. The VSRP backup with the highest
priority value for the VRID is elected as the master for that VRID. The default priority is 100. If
two or more backups are tied with the highest priority, the backup with the highest IP address
becomes the master for the VRID.
• The track priority is used with the track port feature. Refer to “VSRP priority calculation” on
page 221 and “Changing the default track priority” on page 236.
To change the backup priority, enter a command such as the following at the configuration level for
the VRID.
PowerConnect(config-vlan-200-vrid-1)# backup priority 75
Syntax: [no] backup [priority <value>] [track-priority <value>]
The priority <value> parameter specifies the VRRP priority for this interface and VRID. You can
specify a value from 3 – 254. The default is 100.
For a description of the track-priority <value> parameter, refer to “Changing the default track
priority” on page 236.
Example
Following is an example to configure a simple VSRP interface.
Enter the following commands to add tagged ports to a VLAN.
PowerConnect(config)# vlan 30
PowerConnect(config-vlan-30)# tag ethernet 28
Enter the following command to added the IP address.
PowerConnect(config-vlan-30)# router-int ve 30
PowerConnect(config-vlan-30)# interface ve 30
PowerConnect(config-vif-30)# ip address 30.0.0.2/24
Enter the following commands to change the VSRP interface state and initiate VRID state.
PowerConnect(config-vif-30)# vlan 30
PowerConnect(config-vlan-30)# vsrp vri 30
PowerConnect(config-vlan-30-vrid-30)# backup
PowerConnect(config-vlan-30-vrid-30)# ip-address 30.0.0.1
PowerConnect(config-vlan-30-vrid-30)# enable
Saving the timer values received from the master
The hello messages sent by a VRID master contain the VRID values for the following VSRP timers:
• Hello interval
• Dead interval
• Backup hello interval
• Hold-down interval
