A VSD group is a set of physical devices that collectively comprise a single VSD. One physical device acts as the master of the VSD group. The virtual security interface (VSI) of the VSD is bound to the physical interface of the master. The other physical device acts as the backup.
Enter the necessary information:
Group ID: Enter a value from 0 to 7 to identify the VSD group.
Note: By default, when you enable NSRP, the device creates VSD group 0 and makes all existing interfaces virtual security interfaces (VSIs) of this VSD group.
Priority: Enter a number from 1 to 255. devices in an NSRP configuration require both master and backup units. The system with the better priority number (closer to 1) becomes the master. You can either use priority numbers to designate one device as master and the others as backups, or you can leave the priority number at its default (100) and let the VSD group members elect a master automatically.
Enable Preempt: Enable the preempt option for a device that you want to be master of the VSD group. Normally, that device also has the better priority number (closer to 1). In the event of a failover resulting in the new master having a lower priority than the previous master, when the previous master—with the preempt option set—becomes operable and eligible again, it automatically regains mastership of the VSD group.
Preempt Hold-Down Time (sec): Enter an amount of time from 0 to 600 seconds. Using the hold-down time to delay a failover ensures that surrounding network devices have sufficient time to negotiate new links before the new master takes over.
