Hi,
I can imagine that this is very difficult to implement, but this is is must-have-feature on a switch today. Please don’t forget that many NAC-Solutions will do that with SNMP, not everybody is using Radius for that.
We have a lot of questions on the MAX and Balance device to do NAC. Some with Radius and many with SNMP (Switch will send a SNMP-Trap witch the CLient-MAC-Address to the NAC-Server, the server will check the MAC and sends a SNMP write command to the Switch)
Same question is here: Dynamic port tagging on SD-SWITCH
Thanks
Dennis
