Which standard is called Port-Based Access Control?

Explanation:
Port-based access control is about restricting network access at the point where a device connects, until the device authenticates. The standard that defines this framework is 802.1X, which uses an authenticator (like a switch or access point), a supplicant (the client), and an authentication server (often RADIUS). Only after successful authentication does the port switch to an authorized state and allow traffic. 802.11i, by contrast, focuses on securing the wireless link itself with stronger encryption and integrity (WPA2/RSN), not on controlling whether a device can access the network through a port. So the standard that corresponds to Port-Based Access Control is 802.1X.
