N+1 High Availability Firewall requirements

[roger perkin]

I am deploying a 5508 in one DC and another 5508 in another DC running the HA-SKU license

Does anyone know what ports need to be opened for communication between these two controllers?

Thanks

Roger

Hi Roger,

Below gives general port numbers you need to open for intercontroller communication. In your case you need to open UDP 5246 & 5247 as well since AP communicating with the N+1 WLC sits behind firewall.

Also following link should give some additional  port information as well
