Port Guardian
The Port Guardian feature provides a high security managed port lock out mode and when enabled
will power down the port as soon as a link loss status is detected when a cable is disconnected. This
provides high security against network attack by an intruder who accesses the edge device and
disconnects it to then try and connect their own intrusion device (laptop, network sniffer etc.).
To reset a port from a lock out state the network administrator can issue an SNMP reset or can reset
a port by using the CLI via the USB serial port. In PoE models a reset can also be initiated by using
one of the contact inputs.
