Displaying the active interfaces for a VRID
On a VSRP-aware device, you can display VLAN and port information for the connections to the
VSRP devices (Master and Backups).
To display the active VRID interfaces, enter the following command on the VSRP-aware device.
device#show vsrp aware
Aware port listing
VLAN ID VRID Last Port
100 1 3/2
200 2 4/1
Syntax: show vsrp aware
This display shows the following information when you use the aware parameter. For information
about the display when you use the vrid num or vlan vlan-id parameter, refer to
Displaying VRID
information on page 113.
CLI display of VSRP-aware information TABLE 23
Field Description
VLAN ID The VLAN that contains the VSRP-aware device connection with the VSRP Master and Backups.
VRID The VRID.
Last Port 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.
VSRP fast start
VSRP fast start allows non-Brocade or non-VSRP aware devices that are connected to a Brocade
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 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.
device(config)#vlan 100
device(config-vlan-100)#vsrp vrid 1
device(config-vlan-100-vrid-1)#restart-ports 5
Syntax: [no] restart-ports seconds
