Hi,
I would have to dispute that. We've seen NASes across the range (Cisco,
3Com, Extreme) fail to move to the backup/secondary radius server they've
got configured.
report such bugs to the manufacturers of the NAS devices and double
check your device configs -
several of them have quirky ways of failing
over. if you do want to point to a single IP etc then just standard
L4 balancing will work
Yes, though if you're using EAP make sure that requests from a NAS
aren't spread over multiple servers.
- but ensure that the FR boxes are sharing
the same information if you rely on accounting records for decisions
(eg simultaneous usage)
If you're look for a generic solution, layer 7 load balancers are the
answer; We are considering them because NAS based fail-over schemes are
never perfect, you always have to have a few missing responses before
the NAS realises something is up and does something about it.
