PoE Switch

address and the VLAN. In some application, if the Ethernet switch cannot

build the separate MAC address table for different VLANs, there will be a

conflict of MAC address table. To solve this problem, the switch controller

utilizes the VLAN Uplink port to emulate the usage of Independent VLAN

MAC Address Table.

 VLAN Uplink Setting: If VLAN uplink function is enabled and the

destination port of an unicast packet is located at the next VLAN, this

packet will be forwarded to the uplink port. Choose the Uplink Port X for

the port ID. The Uplink X will be the uplink port of its VLAN.

 Note: There is a functional conflict between VLAN striding and VLAN uplink.

Imagine what will happen if both VLAN striding and VLAN uplink are

enabled simultaneously? In this case, the switch selects VLAN striding and

ignores the VLAN uplink setting.
