VLANTagging
Example 1
Example flows for tagged and untagged packets.
Purple flow:
An untagged packet arriving at Port3 is assigned VLAN 100 (the native VLAN), and flows to all egress ports that
will send VLAN100 (Port1 and Port4).
A tagged packet (VLAN100) arriving at Port4 is allowed (VLAN100 is allowed). The packet is sent out from Port1
and Port3. On Port3, VLAN 100 is the native VLAN, so the packet is sent without a VLANtag.
Blue flow:
An untagged packet arriving at Port 4 is assigned VLAN 300 (the native VLAN). Then it flows out all ports that will
send Vlan300 (Port 3).
A tagged packet (VLAN300) arriving at Port3 is allowed. The packet is sent to egress from Port4. VLAN 300 is the
native VLAN on Port4, so the packet is sent without a VLANtag.
