XIQ SE and Windows 11 Authentication EAP TLS

[Asifi]

Hello Community,

We have upgraded from Win 10 to Win 11 and are currently using EAP PEAP as the 802.1x authentication method.  I was told this would no longer work with Win 11 and we would need to implement EAP TLS.  I understand EAP TLS is not available for the version of XIQ SE we have - 23.4.12.3.

However, I believe later version of XIQ SE support EAP TLS.  If this is not the case please let me know. Could anyone let me know which minimum version of XIQ SE supports EAP TLS for XIQ SE and will I need a root certificate to be installed on XIQ SE and the NAC devices?

Is there a guide or similar I could use to Implement EAP TLS?

Currently, we use the built in 802.1x authentication via a LDAP server.  This I believe supports MsCHAP, PEAP and EAP-MsCHAPV2 only.

Many Thanks,

[Asifi]

Hello Everyone,

Apologies for the late reply and thanks to everyone who has replied.  I have checked my version of XIQ SE.  The version I have ExtremeCloud IQ - Site Engine 23.4.12.3

I believe this version should support EAP-TLS.  However, when looking under AAA Rules and Authentication type, I do not have the EAP-TLS option.  Am I looking in the wrong place for this?  Please see screenshot below.

Thanks,

Hi,

Not showing EAP-TLS in the list of conditions for AAA rule does not mean EAP-TLS is not supported.

AAA only gives high-level protocol-based filtering. It would be in the Rules -> Auth Type where you could restrict a rule to EAP-TLS for example.

All XMC / Site Engine releases going back years support EAP-TLS.

FTR, you are on 23.04 which is now outside the 12-month support window. Please plan on performing an upgrade of Site Engine / Control to a supported release; minimum is 24.02.15.05 at this time.

Thanks everyone - lots to ponder and think about.

My last question - we have a wildcard certificate already in use and verified by a CA.  Can we use this as the device cert on the NAC's as this already chains back to out PKI root without having to raise a new CSR and getting this verified by a CA.

Many thanks everyone.
