Network access control (NAC) license violations are product-specific. Each NAC engine handles a NAC license violation in a different way.
To resolve an ExtremeCloud IQ NAC license violation:
Contact your Extreme or Extreme Partner Sales Representative to purchase the required number of licenses, or renew expired licenses.
Increase the allocated NAC quantity to your NAC engine.
On the License Information page, synchronize the cached information from the license pool. Alternately, you can unlink from and relink to the Extreme Portal using your Extreme Portal credentials.
