WLC & ISE RADIUS request load balancing

In larger enterprise wireless deployments is there a way to load balance authentication requests that are sent on a specific SSID to an ISE node?  At the moment you can manually do it per SSID, or per WLC, sending to different primary and secondary nodes.  Is there a way to have the requests on a single SSID properly load balance across multiple ISE nodes?

Re: WLC & ISE RADIUS request load balancing

There is a way but using a load-balancer. I have deployed a solution using F5 LB.

The ISE Community has done an excellent job in documenting how this can be done for F5, Citrix and ACE.

Have a look here.

 

I have experience with the F5 load balancer solution and I will say that doing this comes with great responsibility and knowing what you're doing.   The Cisco/F5 document goes into great length about which flows can be load balanced and how.  Session persistence is a big deal especially with web portals.

 

I also played around with a poor man's load balancer using nginx - it's not bad for simple stuff.  And it's free.
