Switch port protection mechanism

A method to facilitate protection of a switch port, comprising:

• detecting a neighbor change event at a switch port of a network switch;
• determining whether a switch port neighbor device coupled to the switch port is trusted;
• setting a status of the switch port as failed upon a determination that the switch port is untrusted;
• blocking network traffic through the switch port in response to the status that was set;
• and
• generating an alert indicating that untrusted switch port neighbor device is coupled to the switch port.

A non-transitory machine-readable medium storing instructions which, when executed by a processor, cause the processor to:

• detect a neighbor change event at a switch port of a network switch;
• determine whether a switch port neighbor device coupled to the switch port is trusted;
• set a status of the switch port as failed upon a determination that the switch port is untrusted, block network traffic through the switch port;
• and
• generate an alert indicating that untrusted switch port neighbor device is coupled to the switch port.
