VSRP
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.
Brocade#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 652.
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.
Operational ports The member ports that are currently up.
Forwarding ports The member ports that are currently in the Forwarding state. Ports that are
forwarding on the Master are listed. Ports on the Standby, which are in the Blocking
state, are not listed.
TABLE 120 CLI display of VSRP-aware information
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.
