NX5500E max AP supported in high availability mode (1+1)?

[Son_Nguyen2]

Hello everyone,

Can a NX5500E controller be supported max to 1024 AP when it run in HA mode with second NX5500E on unique GUI to manage all AP? (like HA mode of Enterasys controllers)

And the max of controller in Cluster to be supported in a system?

Thanks so much.

Hi Ondrej,

Very clear explanation. So it means Extreme Networks will not support in case of deployment this solution?

Son,

There are two realms you shall consider - cluster master & adopting controller.

• Cluster master - centralized point of configuration

• Adopting controller - controller responsible for AP management

So in this case, you'll still have centralized management (single GUI) and two adopters. However, officially unsupported solution.

Makes sense?

Hi Ondrej,

In this way, do two controllers have a unique GUI (Web UI) to manage all APs in the system?

Son,

As I said - if you extend the adoption capabilities you won't be able to perform failover in case one of cluster members go down. That means you will lose as many APs as single controller cannot handle.

However, you can configure cluster this way - on your own responsibility.

Hi Ondrej,

Can WiNG controllers to be used in HA (active/actve) in order to extend adoption capabilities? Because for some reason, we want to add more controller for this purpose.

Thanks.
