What feature allows a network administrator to bind specific MAC addresses to certain interfaces?

Port Security is a feature typically found on network switches that allows a network administrator to bind specific MAC addresses to particular switch ports, ensuring that only devices with authorized MAC addresses can connect to the network through those ports. This is especially important for enhancing security in a network environment as it helps prevent unauthorized access, such as when an attacker attempts to connect to a network by using a device with a different MAC address.

When port security is configured, the switch can monitor the MAC addresses associated with each port and can take actions such as disabling the port if an unauthorized device is detected, thus protecting sensitive data and resources from potential breaches. Additionally, it enables administrators to set limits on the number of MAC addresses that can be learned on a port, providing further control over the devices that can connect to the network.

Other options, while related to network security, do not specifically serve the purpose of binding MAC addresses to interfaces. VLAN Management is utilized for segmenting networks but doesn't enforce MAC address binding. MAC Filtering, although it sounds similar, typically operates at a broader level compared to the specific implementation of port security on an interface. Access Control Lists (ACLs) manage permissions for IP traffic rather than directly tying MAC addresses to specific ports.
