Port-Based Network Access Control
Port-Based Network Access control provides a means of authenticating and authorizing devices
attached to a LAN port that has point-to-point connection characteristics. It prevents access to ports
that fail authentication and authorization. This feature provides security to ports of the HP GbE2c
Ethernet Blade Switch (GbE2c) that connect to blade servers.
