NAD limit in ISE 2.X

Hello,

When adding a subnet for device management does ISE count all IPs in that range against the 100,000 NAD limit?  

Thanks

Limit is based on actual number of NADs independent of the number of NAD entries used.  For example, if relied 100% on the default NAD entry and 10k NADs provide AAA via that single rule, then total NADs tracked by ISE is 10k, not 1.  Although not represented by a unique IP in configuration, each valid NAD is independently tracked in ISE.

Is there a plan to increase the NAD limit beyond 100k ... lets say 150K ?

We don’t discuss futures in public forum, please reach out to the ISE PM team internally they sales channels with customer engagement info
