ALAXALA Ring Configuration Guide (Edition 1)

(2) Configuration in which devices on every other floor are connected

This configuration is the same as the basic configuration above in the way that a single ring configuration is

used to connect the core switches and routers to the distribution or access switches. However, this configuration

connects ring node devices on every other floor as shown in the following figure, allowing you to keep the wiring

between ring nodes to approximately two-floor lengths.

3.1-2 Configuration of connecting devices on every other floor

In this configuration, the wiring length between each ring node is not more than two floors so that UTP-based

ring lines can be easily used for wiring.

In addition, another advantage of this configuration is that load balancing is possible between the

odd-numbered and even-numbered floor groups, by placing the master node for the ring on the top or bottom

floor.

Notes: Replacement from an STP configuration

Your backbone lines might already have redundancy by using STP. If the lines are aggregated on the core

(in most cases, by using a patch panel), you can use the Ring Protocol by simply changing the wiring on

your patch panel.
