2.2.3 Configuring the Active/Standby Switchover Delay

By configuring the switchover delay time, you can prevent the frequent switchover between the
active interface and the standby interface due to the unstable interface status.
Context
To avoid frequent interface switching due to unstable interface status, the system does not switch
traffic from the active interface to the standby interface until a pre-set delay after the active
interface changes from Up to Down.
