ALAXALA Ring Configuration Guide (Edition 1)

Load balancing is achieved by distributing traffic between the server and the terminals on each floor.

Specifically, you need to configure load balancing as follows:

(1) Path between terminals on floor 1 and the server

- On the backbone (ring) network, use the VLAN mapping that contains the VLANs used on floor 1 (VLANs in

the 100s) and configure the primary port of the ring for the path between devices C10 and F10.

- For STP on base 1 (floor 1), adjust the bridge priority so that device F10 can be the root bridge.

(By default, devices F10 and F11 have a bridge priority of 0, and device F1 has a bridge priority of 32768.

So, by setting the bridge priority of device F11 to 4096, device F10 can be the root bridge.)

- For STP on base 10 (server), you use PVST+ and adjust the bridge priority of the devices so that device C10

will be the root bridge for the VLAN11, a VLAN for data communication with terminals on floor 1.

(By default, devices C10 and C11 have a bridge priority of 0, and device S1 has a bridge priority of 32768.

So, by setting the bridge priority of device C11 for VLAN11 to 4096, device C10 can be the root bridge.)

- Configure VRRP so that device C10 will be the master for the VLANs in the 100s and VLAN11.

With these settings, the communication path between terminals on floor 1 and the server is established as shown

in Figure 3.
