Am running an XCC controller version 05.46.03.0016 and XMC version 22.214.171.124. Aware support for XCC is in version IQ-SE 21.9 or higher, but we are where we are at the moment, with the upgrade scheduled in the future - although I don't believe this issue is related to IQ-SE version (could be wrong).
The error being observed is below, that I am struggling find a reference too.Error Detected for RFC 3576 Authorization: 10.23.23.30: Reauthentication Failed: Unknown Error Code: 0x0(Dec: 0)
Looking at this article there is no mention of that that specific error:Q A: Various RFC3576 RADIUS messages from the Wireless appliance appear in NAC under 'Alert' | Extre...
Equally there is the methodology below I could use to raise a GTAC case, but without the ability for me to capture or replicate the issue with a specific end-system, I believe it makes it challenging for support. The reason is the there so many clients on the network, and no one specific event that I can replicate or know about to reproduce the issue, other then there being reports of connectivity issues every now and thenHow To: NAC Troubleshooting Tips - Debug Methodology for Authentication Issues | Extreme Portal
Here is what the list of logs look like when filter in XMC events under 'RFC 3576'
Initially wondering if anyone recognises the issue, what the cause might be, how to troubleshoot?
Additional note: Forgot to mention XCC is configured for External Captive Portal to Extreme Control. Guests initially land on interim VLAN and subnet, go through registration with verification. Once verification is approved the client is put onto a different VLAN and subnet. Generally this works well, and system has been working that way for many years. Not sure if the errors are new, or fairly recent addition.
