The port backup setting function already divides 4 port backup groups and each group includes 2 ports, the specific ports can be
“Active Port”and “Backup Port”.
Once enable the port backup setting function, only the Active Port will work as a major connection and the Backup Port as a

major connection to avoid network downtime.
When the L2+ Managed PoE+ Switch detects the Active Port of get recovery, then the Backup Port will disconnect
automatically and become a backup fiber connection again.
