I am having an issue with configuring my cisco switch to authenticate with freeradius. My secret is the same on both sides but I keep getting error that the shared secret is not correct. I did a tcpdump of the traffic and then opened in wireshark to see. The password is coming through encrypted as I would suspect. Could this encrypted password be the reason that I am not able to authenticate. Side note: Using wpa supplicant and eapol_test I was able to get a successful test. Only non success is this cisco switch.

ready to process requests.
