14.3 802.1q VLAN Mode
It is also possible to enable 802.1q VLAN mode instead of the default port mode.
Using VLANs, these four switch ports are customizable and each can be configured to act as independent interfaces.
For example, all of these configurations are possible:
• LAN1-4 dedicated as a LAN switch
• LAN1-2 configured as a switch for LAN A and LAN3-4 configured as a switch for LAN B
• LAN1-4 configured as individual network interfaces
• LAN1-2 configured as a switch for LAN A, LAN3 configured for WAN B, and LAN4 configured for WAN C.
Each of the switch ports (LAN1-4 and Port 5) are VLAN aware interfaces. They are capable of functioning as a
standard access or trunk port:
Access Port: Adds a VLAN tag to inbound untagged traffic
Trunk Port: Allows tagged traffic containing specified VLAN IDs
When switching from Port VLAN mode to 802.1q VLAN mode there is no default configuration. See Configuring the
Switch Ports for details on configuring this mode.
