Virtual Switch Redundancy Protocol (VSRP)
8
• Specify that the device is a backup. Since VSRP, like VRRPE, does not have an “owner”, all
VSRP devices are backups. The active device for a VRID is elected based on the VRID
priority, which is configurable.
• Activate the VRID.
The following example shows a simple VSRP configuration.
PowerConnect(config)# vlan 200
PowerConnect(config-vlan-200)# tag ethernet 1 to 8
PowerConnect(config-vlan-200)# vsrp vrid 1
PowerConnect(config-vlan-200-vrid-1)# backup
PowerConnect(config-vlan-200-vrid-1)# activate
Syntax: [no] vsrp vrid <num>
The <num> parameter specifies the VRID and can be from 1 – 255.
Syntax: [no] backup [priority <value>] [track-priority <value>]
This command is required. In VSRP, all devices on which a VRID are configured are backups. The
master is then elected based on the VSRP priority of each device. There is no “owner” device as
there is in VRRP.
For information about the command optional parameters, refer to the following:
• “Changing the backup priority” on page 233
• “Changing the default track priority” on page 236
Syntax: [no] activate
or
Syntax: enable | disable
Configuring optional VSRP parameters
The following sections describe how to configure optional VSRP parameters.
Disabling or re-enabling VSRP
VSRP is enabled by default on Layer 2 Switches and Layer 3 Switches. On a Layer 3 Switch, if you
want to use VRRP or VRRPE for Layer 3 redundancy instead of VSRP, you need to disable VSRP first.
To do so, enter the following command at the global CONFIG level.
PowerConnect(config)#no router vsrp
router vsrp is disabled. All vsrp config data will be lost when writing to flash
To re-enable the protocol, enter the following command.
PowerConnect(config)# router vsrp
Syntax: [no] router vsrp
Since VRRP and VRRPE do not apply to Layer 2 Switches, there is no need to disable VSRP and
there is no command to do so. The protocol is always enabled.
