Example 2 Setup Diagram

2) In VLANs menu add VLAN entries and specify port membership to certain VLANs. Just like the previous example, add ports with untagged traffic (defined by Default VLAN ID) to certain VLAN (black arrows). Also, we need to add ports, which are allowed to forward tagged traffic.

3) At the end, enable strict VLAN filtering to ensure only allowed VLANs can pass through the ports. For hybrid ports to work properly, make sure VLAN Receive is selected as any, otherwise ingress tagged or untagged traffic can be dropped (depending on selected option), but for the trunk port, it is possible to allow only packets with VLAN tag. To filter specific ingress VLAN traffic on hybrid ports, use ACL rules.
