Port 01: 2 Port 05: 5 Port 09: 1
Port 02: 2 Port 06: 1 Port 10: 2
Port 03: 1 Port 07: 1 Port 11: 10 Port 15: 1
Port 04: 5 Port 08: 1 Port 12: 10 Port 16: 1
The PVID of a port must be set to a VLAN ID of which the port is an untagged member.
NOTE:
Port 9 cannot be removed from VLAN 1 because its PVID is set to VLAN 1.
3.  Return to the VLAN Membership page and remove the ports configured in this example (1, 2, 4, 5, 10, 11, 12, 14) from VLAN 1.
The VLANs set up in the this example procedure produce the following results:
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
l
Port 5 and/or 1, it is stripped of its tag and becomes an untagged packet.
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
l
its tag as it leaves the switch and becomes an untagged packet.
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
l
with a VLAN ID value of 10. If the packet leaves Port 11 or 12, it leaves as an untagged packet.
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
l
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.
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
l
parameter is set to enabled.
Example 3
Example 3 illustrates how GVRP is implemented where VLANs configured in a core aggregation switch are automatically learned by wiring-closet switches.
1.  Set up static VLANs in the core switch, as shown in the following table.
VLAN ID Name Port Members (Tagged/Forbidden)
11
Red
1 (T), 3 (T), 2 (F)
22
Green 2 (T), 3 (T), 1 (F)
33
Blue
1 (T), 2 (T), 3 (F)
Port 13: 1
Port 14: 15
