A fire district is documenting wired 802.1X at closet switches. Which role mapping is correct for the endpoint, the access switch, and the RADIUS/ISE server?
Select an answer to reveal the explanation.
Short Explanation
Picture a badge reader at the station door: the firefighter is the one presenting credentials (supplicant), the door gear is the authenticator, and HQ verifies the badge (authentication server). Wired 802.1X uses the same three roles—endpoint, switch, and RADIUS/ISE.
Full Explanation
In IEEE 802.1X, the client (supplicant) exchanges EAP with the network access device (authenticator), which relays EAP to a RADIUS authentication server such as Cisco ISE. Port authorization states (unauthorized, authorized, or limited) follow the outcome of that exchange. Reversing these roles is a common misconception and breaks both design docs and troubleshooting.
