Hi,
When setting up external RADIUS proxy servers for use in ISE via RADIUS server sequence, if there are multiple external servers defined in the sequence, how does failover work amongst these? Does each RADIUS request cycle through the servers defined in the sequence according to the set timeouts, or is health information kept for each external RADIUS server saving the need for every request to try known 'dead' servers in the sequence?
Thanks,
Denis

The bug fix is not yet available in ISE 2.1 so ISE would try all servers in sequence.
