[Sysname] interface ten-gigabitethernet 1/1/6 [Sysname-Ten-GigabitEthernet1/1/6] port-security max-mac-count 100 Related commands display port-security port-security ntk-mode Use port-security ntk-mode to configure the NTK feature. Use undo port-security ntk-mode to restore the default. Syntax port-security ntk-mode { ntk-withbroadcasts | ntk-withmulticasts | ntkonly } undo port-security ntk-mode Default NTK is disabled on a port and all frames are allowed to be sent. Views Ethernet interface view Predefined user roles network-admin Parameters ntk-withbroadcasts: Forwards only broadcast frames and unicast frames with authenticated destination MAC addresses. ntk-withmulticasts: Forwards only broadcast frames, multicast frames, and unicast frames with authenticated destination MAC addresses. ntkonly: Forwards only unicast frames with authenticated destination MAC addresses. Usage guidelines The NTK feature checks the destination MAC addresses in outbound frames to allow frames to be sent to only devices passing authentication, preventing illegal devices from intercepting network traffic. Examples # Set the NTK mode of port Ten-GigabitEthernet 1/1/6 to ntkonly, allowing the port to forward received packets to only devices passing authentication. system-view [Sysname] interface ten-gigabitethernet 1/1/6 [Sysname-Ten-GigabitEthernet1/1/6] port-security ntk-mode ntkonly Related commands display port-security port-security oui Use port-security oui to configure an OUI value for user authentication.
