VSRP
Configuring VSRP fast start
The VSRP fast start feature can be enabled on a VSRP-configured Brocade device, either on the
VLAN to which the VRID of the VSRP-configured device belongs (globally) or on a port that belongs
to the VRID.
To globally configure a VSRP-configured device to shut down its ports when a failover occurs, then
restart after five seconds, enter the following command.
Brocade(config)#vlan 100
Brocade(config-vlan-100)#vsrp vrid 1
Brocade(config-vlan-100-vrid-1)#restart-ports 5
Syntax: [no] restart-ports <seconds>
This command shuts down all the ports that belong to the VLAN when a failover occurs. All the
ports will have the specified VRID.
To configure a single port on a VSRP-configured device to shut down when a failover occurs, then
restart after a period of time, enter the following command.
Brocade(config)#interface ethernet 1/1
Brocade(config-if-e1000-1/1)#restart-vsrp-port 5
Syntax: [no] restart-vsrp-port <seconds>
In both commands, the <seconds> parameter instructs the VSRP Master to shut down its port for
the specified number of seconds before it starts back up. Enter a value between 1 – 120 seconds.
The default is 1 second.
Displaying ports that Have the VSRP fast start feature enabled
The show vsrp vrid command shows the ports on which the VSRP fast start feature is enabled.
The "Restart ports:" line lists the ports that have the VSRP fast start enabled, and the downtime for
each port. Refer to Table 119 on page 652 to interpret the remaining information on the display.
