802.1X Concurrent Connection Limit as a new feature in 6.6.r1 for NPS too?

New upgrade has just arrived 6.6.r1 with new feature:

802.1X Concurrent Connection LimitAerohive RADIUS servers can limit the number of concurrent sessions that a user can maintain. Although it is
common for users to possess multiple network-enabled devices, it is sometimes necessary to discourage their
concurrent use for security reasons. When you are logged in as a superuser, you can limit a user to a specific
number of devices that can connect to the network simultaneously

Can this be used somehow with NPS radius or this is strictly for Aerohive Radius AP as a server?

The new feature is strictly for Aerohive's own RADIUS implementation.

But... A lot of work has gone in to HiveOS 6.6r1 to facilitate session tracking elsewhere in code that handles/tracks RADIUS accounting information in a state machine. (Such as an extension to a RADIUS server that implements this.)

Such extensions can then limit concurrent sessions based on the information that is held there.

The enhancements in this area are documented in the release notes.

I hope that Joe Zhao and Mike Kouri don't hate me too much for my incessant badgering over all this for so long actually! :)

There is one defect in particular that made it through to release in HiveOS 6.6r1 that definitely stops session tracking from being able to take place reliably. (This occurred primarily due to me finding it too late in the release cycle when beta testing, so it is nobody else's fault but mine really...)

The particular issue is...

Acct-Multi-Session-Id is occasionally missing

(The Acct-Multi-Session-Id is needed for tracking a client's connection over roams, which result in multiple RADIUS sessions being accounted for behind the scenes.)

I am trying via a VAR at the moment to get this issue raised to a CFD (Customer Found Defect) to try and get the most expedited resolution reasonably possible. Hopefully without treading on too many toes! :)

There are other open issues that can affect state machine correctness for session tracking, the most important of which is:

Acct-Session-Ids are not constructed to be unique

I am hoping that the subsequent release to HiveOS 6.6r1 can include corrections for these, and a few other more minor issues raised.

We are close, but not quite there yet.

Kind regards,

We don't hate you. Personally I appreciate the occasional reminders because I know I am easily distracted and forget to
