Hey Michael,

In general the appliances is designed to scale up to 2500 concurrent

We have 2 appliances, the NAC3310 goes from 100,250,500, while the
NAC3350 goes from 1500,2500.

Is there a recommended user threshold for an Out-of-band Clean Access
implementation.  How many users should you be able to have on one system
before experiencing congestion related problems?

Thanks,
