Hi Rahul,
General Mesh rules apply. Best practices knowledge base article:
https://support.ruckuswireless.com/answers/000002218 Unleashed can setup a Master GW mode AP, which cannot then be a Root AP
for meshing. Otherwise, any wired AP will be a Root AP. You shouldn't try to mesh
more than 8 APs through one Root AP, and won't get as good of throughput if you go
more than 2 hops. These guidelines should help in most cases.
