Hello!

We are using Extreme Management Center 8.4, V2110 Medium 10.41, Extreme Networks Access Control Engine 8.4, and VMWare 6.5.

For whatever reason, when a client connects to the captive portal and signs in correctly. It will stay there for 5 or 10 minutes unless we force authentication on Management Center. Of course, they get in the quarantine vlan which is 172.x.x.x, but once forced, they get into the correct vlan 10.x.x.x.

Not really sure what’s going on. I can’t follow the last solution in the article that includes the same title, because I cannot find that in Management Center.

Hello, thank you so much for your help. However, the java error that was posted is an issue in version 8.4 of Extreme Networks Access Control.

[com.enterasys.tesNb.server.snmp.reauthentication.DisconnectMessageReauthenticationWorker] (Reauthentication Service Thread19:) Unable to update the authorization level for MAC: 00-1E-4C-9A-CB-47, IP: 172.16.222.64 because of exception:java.lang.NullPointerException

The cause of the issue is due to changing re-authentication on the Access Controller.

The unofficial workaround is to enforce using Java NAC Manager. However, that doesn’t fix the issue.

Upgrading both Extreme Networks Management Center and Extreme Networks Access Control to 8.5 corrected the issue entirely.
