controller clustering with remote ap's

hi, 

we tried to cluster the controllers but afterwards all remote ap's went down.

 

I cannot see how clustering for RAP's should work because they connect through NAT to the controller vrrp ip and cannot reach the individual controllers.

Why is this not working? and can't i disable clustering for RAP's?

Hi,

are you working with version 8.x software or version 6.x ?

Re: controller clustering with remote ap's

If you using AOS8 clustering NAT is not supported with this design , you will need to assign direct public address to each controller

Re: controller clustering with remote ap's

yes, 8.1.2 with mobility master.

And no, we are not going to put a public ip on the controller.

 

Re: controller clustering with remote ap's

I wasn’t suggesting you do but that’s the only way you can support RAPs while using clustering.

Otherwise you will need to have separate controllers (not part of a cluster) for your RAPs or use the existing controllers with no clustering

Re: controller clustering with remote ap's

As mentioned above, it's a known/stated limitation with AOS8.x. This is due to how controller information is signaled to APs when clustering is enabled, via the nodelist, which takes priority over the previous controller discovery options.

 

The previous methods of RAP redundancy using LMS and Backup LMS IPs in combination with VRRP are still options, but due require that the controller not be a part of a cluster.

Re: controller clustering with remote ap's

will this be fixed in a future version?

 

This means in order to use this we have to buy 2 extra controllers.
