VSRP fast start

VSRP fast start allows non-Dell PowerConnect or non-VSRP aware devices that are connected to a
Dell PowerConnect device that is the VSRP Master to quickly switchover to the new Master when a
VSRP failover occurs
This feature causes the port on a VSRP Master to restart when a VSRP failover occurs. When the
port shuts down at the start of the restart, ports on the non-VSRP aware devices that are
connected to the VSRP Master flush the MAC address they have learned for the VSRP master. After
a specified time, the port on the previous VSRP Master (which now becomes the Backup) returns
back online. Ports on the non-VSRP aware devices switch over to the new Master and learn its MAC
address.
Configuring VSRP fast start
The VSRP fast start feature can be enabled on a VSRP-configured Dell PowerConnect 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.
PowerConnect(configure)#vlan 100
PowerConnect(configure-vlan-100)#vsrp vrid 1
PowerConnect(configure-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.
PowerConnect(configure)#interface ethernet 1/1
PowerConnect(configure-if-1/1)#vsrp restart-port 5
Syntax: [no] vsrp restart-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 VRID.
The most recent active port connection to the VRID. This is the port connected
to the current Master. If a failover occurs, the VSRP-aware device changes the
port to the port connected to the new Master. The VSRP-aware device uses
this port to send and receive data through the backed up node.
