I have an HP 600 M602 printer trying to authenticate with ISE 2.0. The authentication is failing. The report states the following: "Extracted EAP-Response/NAK packet requesting to use unsupported EAP protocol; EAP-negotiation failed"
Root Cause: "Extracted from the RADIUS message an EAP-Response/NAK packet, rejecting the previously-proposed EAP-based protocol, and requesting to use another protocol instead, per the configuration of the client's supplicant. However, the requested EAP-based protocol is currently not supported by ISE."
HOWEVER, I have 802.1X disabled on the printer. It's not supposed to be communicating via EAP. We've installed different drivers on the printer. Nothing is stopping this printer from using EAP. How do we resolve this issue other than turning off the printer or turning on 802.1X and see what happens?
