Configuring load balancing
Interface backup detects the data traffic on the active interface to determine whether to bring up or shut
down the standby interface.
When multiple standby interfaces are assigned the same priority, they are brought up or shut down
depending on the order they are configured:

interface.
• The standby interface configured later is shut down first and exits load balancing with the active
interface.
