Standard: Default mode of the switch. In this mode, it works as an unmanaged switch;all ports can communicate with each other separately. Priority: In this mode, port 23,24,SFP1 and SFP2 serve as uplink ports, ports 1 ‒ 8 serve as high priority port. All ports can communicate with each other separately. Extend: In this mode, data rate of ports 17 - 22 reduces to 10 Mbps, the maximum transmission distance can be 250 meters, and all ports can communicate with each other. VLAN: In this mode, ports 1 - 22 of the switch can communicate with port 23,24, SFP1, SFP2 separately, but cannot communicate with each other. You can enable this mode to reduce broadcast storm and isolate DHCP broadcast.
