What is vlanVoicePortSecure?
This read-write TruthValue puts a port into Secure Mode for Voice VLAN membership, meaning only frames whose source MAC prefix matches one of the configured OUI table entries are accepted, with all others dropped. An admin enables this to prevent non-phone devices from riding along on a port that's meant exclusively for a recognized VoIP handset. For example, enabling vlanVoicePortSecure on a phone port ensures a PC plugged in behind or alongside the phone can't sneak untagged traffic into the Voice VLAN.
