What is the primary function of port security on network switches?
Monitor traffic patterns to detect anomalies
Limit the number of MAC addresses allowed on a switch port
Limit the bandwidth usage on a network
Encrypt data transmitted from one port to another
Port security is a layer 2 traffic control feature used mainly to limit the number of MAC addresses allowed on a single port. This prevents unauthorized devices from accessing the network and mitigates risks like MAC flooding. Limiting bandwidth does not relate directly to security, and monitoring traffic patterns and transmitting data securely are functions more closely associated with network monitors and encryption protocols, respectively.
