How to configure dynamic MAC address port security on the SX300 series using 1.2.7.76 code
1.) Connect the desired computer to a port and verify the MAC address populated in the dynamic table
2.) Configure the port security on the corresponding port, on my example FE1. I chose action shut down upon violation.
3.) Connect a different device to the corresponding port, this will create the shutdown condition as soon as the deviant MAC address is detected
