Cluster Question

[Matt Richardson_]

I'm a little confused as to how the clustering works on the UAC devices

I have IC4500's that I plan on clustering and using first for our wireless authentication and then later wired as well. The big question I can't seem to find a definite answer to is for Active/Active is a load balancer required or do I simply just have to configure both IC's Ip addresses as radius servers on my wireless appliance?

Hello Matt,

In active/active mode, you have the option of using an external load balancer with an IC cluster. In case of a load balancer, all the nodes actively handle user requests sent by the load balancer . The load balancer hosts the cluster VIP and routes radius requests to an IC Series device based on sessions. If an IC goes off line, the load balancer adjusts the load on the active IC and that will be transparent to the users.Alternatevly you could configure both the IC's IP in Wireless device as Primary and Secondary Radius server as well, how-ever in such case the fail-over needs to be done at the wireless device itself.

Thanks
