802.1x limit access


mygoal is to limit access to WiFi network from one device per one user. I'm using 802.1x, PKI infrastructure and Cisco ACS. I have already read  please click article. My question is, is it possible somehow? Do I need extra server feature etc...?


Thanks in advance.

Are you using RADIUS accounting on your ACS box?

Re: 802.1x limit access

Yes, I'm using Radius accounting on ACS 5.5. I can check logged in users on System Administration ->Users->Purge User Sessions, but I do not know how to use this information.


Do you have any good hint?

Re: 802.1x limit access

that link points to captive portal settings, that won't be useful in your situation.


if something like this is possible then it depends on your RADIUS server, in this case ACS. i would try googling on that, or ask on the Cisco forum.

Re: 802.1x limit access

You are right. I just wanted to pay attention on sentence For 802.1x authentication, there is no means of restricting the active sessions per user, meaning, a user can log on to multiple client devices at the same time.
