In the document below I see that WLC device certificate be installed on the Cisco WLC as part of the overall getting EAP working process. If the device certificate expires - what would be the impact of any configured EAP-TLS? PEAP? It seems like I've read elsewhere that the certificates that mattered for EAP-TLS were on the wireless client and at the RADIUS server.

You can view the device certificate via WLC GUI at Security/IPSec Certs/ID Certs.

You only need a certificate on the WLC if you're doing local EAP or web-auth.

To process EAP-style authentication with RADIUS it's not necessary to have a certificate on the WLC; only on the RADIUS server. Depending on the type of EAP authentication used you may also need a certificate on the client too.

That explains exactly what I saw among a group of WLC's - some with expired certs and some not. And it turns out the ones with good certs were doing EAP-TLS but with local EAP. Thank you very much for clarifying this!
