Port Security Configuration Examples
The security modes of the port security feature provide extended and combined use of 802.1X
authentication and MAC authentication. They apply to scenarios that require both 802.1X
authentication and MAC authentication. For scenarios that require only 802.1X authentication or MAC
authentication, you are recommended to configure 802.1X authentication or MAC authentication rather
th an port security for simplicity.
Port Security Overview
Introd uction
Port security is a security mechanism for network access control. It is an expansion to the current
802.1X and MAC authentication.
Port security allows you to configure a port to operate in an intended securit
address learning or user authentication on the port. This enables the switch to learn legal source MAC
addresses, so as to implement network security management as needed.
With port security enabled, packets whose s
a security mode are considered illegal packets; the events that cannot pass 802.1X authentication or
MAC authentication are considered illegal.
Upon detection of illegal frames or events, the switch takes the pre-defined action automatically. While
