VLANs

Figure 5 802.1Q tagging (after port-based VLAN assignment)

In the following figure, the tagged incoming packet is assigned directly to VLAN 2 because of the tag assignment in the packet. Port 5 is configured as a tagged member of VLAN 2, and port 7 is configured as an untagged member of VLAN 2.

Figure 6 802.1Q tag assignment

As shown in the following figure, the tagged packet remains unchanged as it leaves the switch through port 5, which is configured as a tagged member of VLAN 2. However, the tagged packet is stripped (untagged) as it leaves the switch through port 7, which is configured as an untagged member of VLAN 2.
