|Title||Standard for Local and metropolitan area networks–Port-Based Network Access Control|
|Committee||WORKING GROUP 802.3|
IEEE 802 LANs are deployed in networks that convey or provide access to critical data, that support mission critical applications, or that charge for service. Protocols that configure, manage, and regulate access to these networks and network-based services and applications typically run over the networks themselves. Port-based network access control regulates access to the network, guarding against transmission and reception by unidentified or unauthorized parties, and consequent network disruption, theft of service, or data loss.
Data frames are transmitted and received using the MAC Service specified in IEEE Std 802.1AC. Port-based network access control:
Uses the unsecured MAC Service provided by an end station or bridge port to support
