Specifications

The specific ports shown in the previous figure have the following PVID settings. The PVID settings for each port are configured in the Port Settings
page.

The PVID of a port must be set to a VLAN ID of which the port is an untagged member.

3. Return to the VLAN Membership page and remove the ports configured in this example (1, 2, 4, 5, 10, 11, 12) from VLAN 1.
The VLANs set up in this example procedure produce the following results:
l If an untagged packet enters Port 4, the switch tags it with a VLAN tag value of 5. The packet can be forwarded to Port 5 and/or 1. As the packet
leaves Port 5 and/or 1, it is stripped of its tag and becomes an untagged packet.
l If a tagged packet with a VLAN tag value 5 enters Port 4, the packet has access to Ports 5 and 1. If the packet leaves Port 5 and/or 1, it is stripped of
its tag as it leaves the switch and becomes an untagged packet.
l If a tagged packet with a VLAN tag value 10 enters Port 9, it can be forwarded to Ports 1, 10, 11, and 12. If the packet leaves Port 1 or 10, it is tagged
withaVLANIDvalueof10.IfthepacketleavesPort11or12,itleavesasanuntaggedpacket.
l If a tagged packet with a VLAN tag value 15 enters Port 9, it is forwarded to ports in VLAN 15, even though Port 9 is not a member of VLAN 15. The
tagged packet enters Port 9 because the Ingress Filtering parameter for Port 9 is set to disabled (the default). If Ingress Filtering is disabled, a tagged
packet is forwarded if its VLAN tag value matches a VLAN ID already configured on the switch, otherwise it is dropped.
l If a tagged packet with a VLAN tag value of 1 enters Port 10, it is dropped because Port 10 is not a member of VLAN 1 and its Ingress Filtering
parameter is set to enabled.
