GS108T and GS110TP Smart Switch Software Administration Manual • Packets leaving the switch are either tagged or untagged, depending on the setting for that port's VLAN membership properties. A U for a given port means that packets leaving the switch from that port are untagged. Inversely, a T for a given port means that packets leaving the switch from that port are tagged with the VLAN ID that is associated with the port. The example given in this section comprises numerous steps to illustrate a wide range of configurations to help provide an understanding of tagged VLANs. VLAN Example Configuration This example demonstrates several scenarios of VLAN use and describes how the switch handles tagged and untagged traffic. In this example, you create two new VLANs, change the port membership for default VLAN 1, and assign port members to the two new VLANs: 1. In the Basic VLAN Configuration screen (see VLAN Configuration on page 84), create the following VLANs: • A VLAN with VLAN ID 10. • A VLAN with VLAN ID 20. 2. In the VLAN Membership screen (see VLAN Membership Configuration on page 86) specify the VLAN membership as follows: • For the default VLAN with VLAN ID 1, specify the following members: port 7 (U) and port 8 (U). • For the VLAN with VLAN ID 10, specify the following members: port 1 (U), port 2 (U), and port 3 (T). • For the VLAN with VLAN ID 20, specify the following members: port 4 (U), port 5 (T), and port 6 (U). 3. In the Port PVID Configuration screen (see Port VLAN ID Configuration on page 87), specify the PVID for ports g1 and g4 so that packets entering these ports are tagged with the port VLAN ID: • Port g1: PVID 10 • Port g4: PVID 20 4. With the VLAN configuration that you set up, the following situations produce results as described: • If an untagged packet enters port 1, the switch tags it with VLAN ID 10. The packet has access to port 2 and port 3. The outgoing packet is stripped of its tag to leave port 2 as an untagged packet. For port 3, the outgoing packet leaves as a tagged packet with VLAN ID 10. • If a tagged packet with VLAN ID 10 enters port 3, the packet has access to port 1 and port 2. If the packet leaves port 1 or port 2, it is stripped of its tag to leave the switch as an untagged packet. • If an untagged packet enters port 4, the switch tags it with VLAN ID 20. The packet has access to port 5 and port 6. The outgoing packet is stripped of its tag to become an untagged packet as it leaves port 6. For port 5, the outgoing packet leaves as a tagged packet with VLAN ID 20. Appendix B: Configuration Examples | 245
