Configuring Port Security Features; Configuring Ntk; Configuring Intrusion Protection - HP 3600 v2 Series Security Configuration Manual

To do...
Set the port security mode
NOTE:
After enabling port security, you can change the port security mode of a port only when the port is
operating in noRestrictions (the default) mode. To change the port security mode for a port in any other
mode, use the undo port-security port-mode command to restore the default port security mode first.

Configuring port security features

Configuring NTK

The NTK feature checks the destination MAC addresses in outbound frames to make sure that frames are
forwarded only to authenticated devices. Any unicast frame with an unknown destination MAC address
is discarded. Not all port security modes support triggering the NTK feature. For more information,
see Table 10.
The NTK feature supports the following modes:
ntkonly—Forwards only unicast frames with authenticated destination MAC addresses.
•
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.
Follow these steps to configure the NTK feature:
