Explanation
IEEE 802.1x is the standard for port-based Network Access Control (NAC). It requires devices to authenticate to the network before being granted access to network resources, using an authentication framework with three roles: the supplicant (the client device), the authenticator (the switch or wireless access point), and the authentication server (typically a RADIUS server). Until the client authenticates successfully, the switch port only allows EAP (authentication) traffic. 802.1q is the IEEE standard for VLAN tagging (trunk links), not access control. 802.3 is the standard for wired Ethernet. 802.11n is a Wi-Fi standard defining wireless transmission speeds and techniques.
