Brocade FastIron Ethernet Switch Platform and Layer 2 Switching Configuration Guide - Manual (Page 117)

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.
device(config)#interface ethernet 1/1
device(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 22 on page 113 to interpret the remaining information on the display.
VSRP and MRP signaling
A device may connect to an MRP ring through VSRP to provide a redundant path between the device
and the MRP ring. VSRP and MRP signaling ensures rapid failover by flushing MAC addresses
appropriately. The host on the MRP ring learns the MAC addresses of all devices on the MRP ring and
VSRP link. From these MAC addresses, the host creates a MAC database (table), which is used to
establish a data path from the host to a VSRP-linked device. The following figure below shows two
possible data paths from the host to Device 1.
