A few question about mesh 8.5 / 8.8 network

[l.buschi]

I have a few questions about best practices for mesh network deployment:

I'm using WLC 3504 and 1560 APs.

- is it better 8.5 release or 8.8?

- on mesh bridge access-points:

       -- what about channel width of backhaul link? 20-40 or 80MHz on RAP access-points?

       -- with ethernet bridging enabled, which is the difference between vlan support on mesh tab and vlan support on gigabit ethernet port? which native vlan do I have to use on both tabs? Which vlan do i need to configure on rap's switch port? and which vlan on map's switch port? (i need to connect a switch on maps in order to carry wired vlan's over mesh network.

- on general mesh:

    -- extended backhaul client access yes/no? what is this function for?

    -- mesh backhaul RRM yes/no?

Thank you very much.

Best

Johnny

As far as code, that is up to you on what features you want and your testing for stability. Have you reviewed the mesh guide as it goes through the setup and would answer your questions:

Client access on backhaul, I would say no, this is also documented in the guide. RRM fro the backhaul, I would also say no as it might break your backhaul if the channel has to change.
