AV Line of Fully Managed Switches M4250 Series Main User Manual • When a tagged packet enters a port, the tag for that packet is unaffected by the default VLAN ID setting. The packet proceeds to the VLAN specified by its VLAN ID tag number. • If the port through which the packet enters is not a member of the VLAN as specified by the VLAN ID tag, the packet is dropped. • If the port is a member of the VLAN specified by the packet's VLAN ID, the packet can be sent to other ports with the same VLAN ID. • Packets leaving the switch are either tagged (T) or untagged (U), depending on the setting for that port's VLAN membership properties. A U for a port means that packets leaving the switch from that port are untagged. Inversely, a T for a port means that packets leaving the switch from that port are tagged with the VLAN ID that is associated with the port. The example in this section comprises numerous steps to illustrate a wide range of configurations to help provide an understanding of tagged VLANs. VLAN configuration examples 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 page (see VLANs on page 190), create the following VLANs: • A VLAN with VLAN ID 10. • A VLAN with VLAN ID 20. 2. On the VLAN Membership page (see Configure membership interfaces for a VLAN on page 199) 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. On the Port PVID Configuration page (see Change the port VLAN ID settings on page 202), specify the PVID for ports g1 and g4 so that packets entering these ports are tagged with the port VLAN ID: • Port 1: PVID 10 Configuration Examples 767 Main User Manual
