◦ Extensible Authentication Protocol-Transport Layer Security (EAP-TLS)
◦ EAP-Tunneled TLS (TTLS) or Microsoft Challenge Handshake Authentication Protocol Version 2 (MSCHAPv2)
The ISE we use only accepts TLS 1.2 and TLS 1.3. As soon as the AP tries to connect to the network the ISE shows that the connection is refused because TLS 1.0 or 1.1 is used by the AP.
Is it possible to configure in the CLI of the AP the TLS version?
- The latter may not be possible but also make sure that the current software version being used on the AP is no too old. If it would be , then upgrade to the most recent release and verify the problem again.
