Wireless Access

Hi,
currently we have 7220 cluster with two nodes serving around 500 APs.
In near future we will add around 700-800 new APs to the cluster.
Am I right, that if one controller fails, it can't handle all APs, because the limit of 7220 is 1024 APs?

We have one blank 7210. Can we add this to the cluster, so if a 7220 fails the cluster still can handle 1536 APs (7220: 1024 + 7210: 512)?

- A mix of hardware devices and the Mobility Controller Virtual Appliance-based controller is not supported.

- A mix of 7200 Series controllers and 7000 Series controllers within the same cluster is not recommended due to disparity in capacity between the two controller series models. However, you can use these devices in the same cluster when you want to migrate from a smaller cluster like 7000 series controllers to a larger cluster with 7200 Series controllers.

Other that that, your calculation should work just fine.
