What is secureNeedToKnowMode?
This configurable integer (1-8) determines which frames reach an authorized port: all frames, only authorized devices, authorized plus broadcast, or authorized plus broadcast and multicast. Operators use it to restrict traffic visibility and prevent unauthorized eavesdropping. Setting to 5 allows only known devices, broadcasts, and multicast on the port.
