Port configuration descriptions
• Port 1 and Port 2 are configured with Primary VLAN ID=10. This connects the two ports
allowing traffic to be switched between them (as shown by the dotted line). Both ports are
configured as Tagged, which means that outgoing traffic on these ports is tagged with VLAN
10, and incoming traffic must also be tagged with VLAN 10. In addition, traffic from these
ports is also switched on the Uplink port. Traffic on the Uplink port is always tagged with the
configured VLAN ID, which in this case is 10.
• Port 3 is configured with Primary VLAN=Uplink tagging and Primary VLAN ID=20. This means
that traffic on this port is untagged. However, traffic is forwarded onto the Uplink port with
VLAN=20. In addition, the port is configured with a Secondary VLAN=10, which enables it
to exchange traffic on VLAN 10. Port 3 and Port 4 are both on the same Uplink VLAN allowing
untagged traffic to be exchanged between the ports.
• Port 4 is configured with Primary VLAN=Uplink tagging and Primary VLAN ID=20. This means
that traffic on this port is untagged. However, traffic is forwarded onto the Uplink port with
