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 NE2552E Flex Switch
(NE2552E) that connect to blade servers.
