One note after implementing EAPBALANCE.

Any input would be helpful. My thought is to lower the values for Retries etc.MH On 2013-05-10, at 11:41 AM, Michael Hulko wrote:Thanks for the suggestion.. this seems to alleviate the timeouts that I had noticed previously.

If so, you would need to use <AuthBy EAPBALANCE> to make sure the EAP authentication sessions are always handled by the same IAS server. Otherwise you will see failures and timeouts when the IAS servers receive requests they are not expecting. The Trace 4 log was not included, but I'd first check how it works with EAPBALANCE.
