Hello everyone, meet again, I'm your friend Quanstack Jun.

Mux VLAN is a layer 2 isolation technology on the switch, which implements resource control based on VLAN.Mux VLAN technology includes primary VLAN and secondary VLAN; secondary VLAN is divided into isolated VLAN and group VLAN.A primary VLAN can contain multiple group VLANs at the same time, and can only contain at most one isolated VLAN.Ports in the same group VLAN can communicate with each other, but ports in different groups of VLANs cannot communicate; ports in the same isolation group cannot communicate;

But the ports in the isolated VLAN and the group VLAN can communicate with the ports in the main VLAN.

Briefly describe the realization principle of port isolation

Port isolation is a layer-2 isolation technology implemented on switches. Ports belonging to the same isolation group cannot communicate, but ports belonging to different isolation groups can communicate; ports with port isolation enabled are isolated from ports that are not enabled.users can also communicate with each other.
