dynamic backbone route on wireless backbone passively when failure node occur. Because DC-MESH is a
passive mechanism, link in wireless backbone can be more efficient than normal MESH.
DC MESH feature description
There are two DC-MESH mode devices in DC-MESH deployment:
Gateway Node
"Gateway Node" will be the first device of a Daisy Chain topology, a "Gateway Node" connects wireless
network and wire network. The "Gateway Node" device should have a wireless interface configured as
Access Point mode to be the very beginning wireless device of a Daisy Chain wireless backbone.
Normal Node
Except "Gateway Node", other EKI-632XAG series devices in a DC-MESH topology are "Normal Node".
"Normal Node" will be able to switch wireless connection from an Access Point to the other when failing
wireless occurred.
