What is the solution for 3,000 APs?

[Amarin_Ngaokraj]

Hi I'm new to Identify Wireless Appliance. I know that C5210 can support up to 2000 APs which need HA mode. My questions are below

1. What is the solution for using more than 2000 APs? Can controller work like Main controller and another controllers are slave? If can how many controller can work together is there limitation?

2. For AP licenses I know that there is license pool and is this work with multiple controllers?

Anyone has some documents to explain this please share to me.

Regards,

1. the Extreme solution use the 1:1 redundancy concept = you put two controller in a HA pair.
If you've more then 2000 APs you just use more pairs for redundancy.
i.e. my customer has 4x C5210 for up to 4000APs.
You'd configure master/slave but that would mean that you connect only 1000APs to your C5210 HA pair.

2. controller in a HA pair could share licenses, i.e. EWC#1 and EWC#2 have both 300 licenses installed so you'd connect up to 600APs in any configuration so 600APs on EWC#1 and 0 on EWC#2 or vice versa or distributed on both
