Why are services interrupted after the original active firewall preempts

Services are normal after the active/standby switchover, but services are interrupted after the active firewall preempts. The possible cause is that the network has not converged or sessions are not completely backed up. Besides, if a switch fails, its interfaces may go up and down repeatedly when the switch restarts. If the firewall preempts during the process, services may be interrupted.

In this case, adjust the preemption delay of the original active firewall.
