【Default】
It is defaulted to be preempt with the delay time being 0
【Command configuration mode】
VLAN interface configuration mode
【Usage】
Once there is a Master in the backup group，and there is no failure, and other
switch though has configured to prossess superior priority,it will not be Master
unless the preemption is configured. If the switch is configured to be preempt,
once it prossesses its priority is superior than the Master, it will be the Master.
Accordingly, the original Master will be the backup. The delay time can be
configured at the same time as the preemption, which can delay backup being
Master. The aim of delay time is: In unstable network, if Backup doesn’t
receive the packet from Master on time, it will become Master (the reson why
Backup cannot receive the packet is because of the congestion of the network,
not the abnormal working of Master). So waiting for a certain time, the packet
