Example 2

Example of invalid tagged VLAN.

Green flow

Between Port1 and Port2, packets are assigned to VLAN 1 at ingress, and then the tag is removed at egress.

Blue flow

Incoming on Port 3, a tagged packet with VLAN value 100 is allowed, because 100 is the Port 3 native VLAN (the hardware VLAN table accepts a tagged or untagged match to a valid VLAN).

The packet will be sent on port1 and port4 (with packet tag 100).
