Well you can certainly use different types of NAS with Radiator, all you have
to do is specify the corresponding NasType as you already know. To manage
simultaneous use, all copies of Radiator must use the same SessionDatabase SQL,
so all three radius hosts must be configured to use the same SessionDatabase on
the SQL host.
To assist us in dealing with the Cisco NAS-Port problems, it would be very
helpful if you could send us copies of the accounting requests and the
corresponding SNMP query results so we can see the differences. If you could
also tell us what version of Cisco IOS you are using that would help too.
