We have XMC and 3 NAC servers.we also have many devices with different OS for applied which userd certificate authorization. Is it possible to set up an alert on xmc , for example, if a client connects and its certificate has a validity period of less than 30 days, then xmc generates an alert?</P> Fri, 18 Nov 2022 11:20:32 GMT nor61k 2022-11-18T11:20:32Z https://community.extremenetworks.com/t5/extremecontrol/xmc-client-certificate-expiration-monitoring/m-p/93797#M321 <P>Hello!

If you're referring to client certificates part of EAP-TLS transactions I don't think we have any ability to intercept and alarm and say essentially " a client is connecting via EAP-TLS with a client cert that is expiring in xx days ". We already have alarms built in that will fire for the *server* certificates hosted in Control (i.e. RADIUS server cert) with NOTICE and WARNING periods up to expiration.</P> Fri, 18 Nov 2022 13:52:56 GMT https://community.extremenetworks.com/t5/extremecontrol/xmc-client-certificate-expiration-monitoring/m-p/93802#M322 Robert_Haynes 2022-11-18T13:52:56Z
