become the master switch when it finds its priority is higher than that of the current
master switch, and the former master switch becomes a backup switch accordingly.
You can configure an S3900 series switch to operate in preemptive mode. You can also
set the delay period. A backup switch waits for a period of time (the delay period) before
becoming a master switch. Setting a delay period aims at:
In an unstable network, backup switches in a backup group possibly cannot receive
packets from the master in time due to network congestions even if the master operates
properly. This causes the master of the backup group being determined frequently.
With the configuration of delay period, the backup switch will wait for a while if it does
not receive packets from the master switch in time. A new master is determined only
after the backup switches do not receive packets from the master switch after the
specified delay time.
Note:
You can use the undo vrrp vrid preempt-mode command to set switches in a backup
group to operate in non-preemptive mode.
