LAN Division Function

VLAN-based ports can be created using the LAN division function. Multiple virtual LAN interfaces can be built using a switching hub as a LAN interface. A distinct IP address can be given to each interface, and routing is also an option between them. The LAN division function provides both fundamental and advanced features. The division method used by the LAN (switching hub) distinguishes them from one another. The switching hub’s ports all act as distinct LAN interfaces in their default configuration. To build a single LAN interface, you can flexibly combine the switching hub ports in the extended function (VLAN interface). If you switch between ports on the same VLAN interface, it will work.

Port-based VLAN:

Without relying on physical topology, a VLAN (virtual LAN) groups together individual LAN segments and manages them as a single LAN. VLAN comes in a variety of forms. Yamaha’s routers are compatible with a Tag VLAN and a port-based VLAN, both created through the LAN division function.  You can manage the broadcast domain (the ARP request range) per port in a VLAN that is based on ports. Setting up and managing a switching hub with a port-based VLAN is easier than physically changing the wiring because the network that the connection terminal is a part of can be changed at any time.

Operations of the LAN Division Function:

An 8-port switching hub connected to the lan1 interface will be used as an example to demonstrate how the LAN division feature works.

Read the Images: 

Each image has an 8-port switching hub at the bottom and a LAN interface at the top. One IP address can be given to each LAN interface, and the associated switching hub can use that IP address. See the Command section for the name of the interface as seen in the picture.

1. All ports on the switching hub function as one LAN interface when the LAN division feature is disabled. The IP address 192.168.1.1/24 was given to lan1 (ports 1 through 8).

2. All ports on the switching hub act as separate LAN interfaces in the LAN division function’s fundamental mode. The switching hub ports 1 through 8 correspond to the LAN1.1 to LAN1.8 interfaces.

3. The interfaces vlan1 to vlan8 (also known as VLAN interface) are used in the LAN division function’s extended mode. These interfaces are not connected to a specific switching hub port, in contrast to the fundamental function. You can freely switch the division mechanism by setting which VLAN interface each port belongs to. Ports 1 through 3 are associated with vlan2, ports 4 through 6 with vlan5, port 7 with vlan7, and port 8 with vlan8 in the picture. If you switch between ports on the same VLAN interface, it will work.
