3. Set up the Port VLAN IDs as shown in the following illustration:
The specific ports shown in the previous illustration have the following port VLAN ID settings. The port VLAN ID settings for each port are configured in the
PVID Settings page:
Port 01: 2 Port 05: 5 Port 09: 10 Port 13: 10
Port 02: 1 Port 06: 1 Port 10: 10 Port 14: 15
Port 03: 1 Port 07: 1 Port 11: 10 Port 15: 1
Port 04: 1 Port 08: 1 Port 12: 10 Port 16: 1
The VLANs set up in the preceding procedure produce results as follows:
If an untagged packet enters Port 4, the switch tags it with a VLAN tag value of 1. Since Port 4 does not have membership with VLAN ID 1, the default,
l
the system drops the packet.
If a tagged packet with a VLAN tag value 5 enters Port 4, the packet has access to Ports 3 and 1. If the packet leaves Port 3 and/or 1, it is stripped of
l
its tag as it leaves the switch and becomes an untagged packet.
If an untagged packet enters Port 1, the switch tags it with a VLAN tag value of 2. It is then dropped since Port 1 has no membership with VLAN ID 2.
l
If a tagged packet with a VLAN tag value 10 enters Port 9, it has access to Ports 1, 10, 11, and 12. If the packets leave Port 1 or 10, they are 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 1 enters Port 9, it is dropped since Port 9 does not have membership with VLAN ID 1.
