Wired Intelligent Edge

Hi ,

I have to set up a aruba controller (7240) in hub and spoke environment , in 2 spoke we have to install total 80 aruba APs(325).

What is the best design for this architecture ???

How many controller will reqiure for this setup ???

And which precaution we need  to take for configuration & installation ??

You should start with the Aruba Networks Campus Network Validated Reference Design Guide here:  http://community.arubanetworks.com/t5/Validated-Reference-Design/Campus-Network-Design/ta-p/155134

In Aruba it is called Master (writeable controller), local (read-only controller), not hub and spoke.  According to the datasheet here:  http://www.arubanetworks.com/assets/ds/DS_7200Series.pdf a 7240 can terminate 2048 access points, so if you are not going over 2000 for each site, in theory you could use 2 7205s.  Please see the rest of the Campus Validated Reference Design guide for design ideas.

Thanku Joseph for reply and got the document which you have mention in the link , it will definitely help for my setup .

if i will face any issue during the setup i will let u know.

Thanku once again.

I forgot to ask you that which mode (CAP or RAP) is preferable for Aruba APs(325) on local side because dhcp server , firewall device  and internet traffic is in master location .

RAPs (remote APS) are only for remote deployments where there is a NAT boundary between the access points and the controller.  It should be a CAP (Campus AP).

Thank you Joseph for your quick reply and support . 

How many local controllers can a Master (7240) support
