Configuring port security features

Configuring NTK

The NTK feature checks the destination MAC addresses in outbound frames to make sure frames
are forwarded only to authenticated devices.
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.
The NTK feature drops any unicast frame with an unknown destination MAC address. Not all port
security modes support triggering the NTK feature. For more information, see
To configure the NTK feature:
Step
1. Enter system view.
2. Enter interface view.
3. Configure the NTK feature.

Configuring intrusion protection

Intrusion protection enables a device to take one of the following actions in response to illegal
frames:
•
blockmac—Adds the source MAC addresses of illegal frames to the blocked MAC address list
and discards the frames. All subsequent frames sourced from a blocked MAC address are

To specify the
userLoginWithOUI mode,
you must enter Layer 2
Ethernet interface view.
By default, a port operates in
noRestrictions mode.
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, first use the undo
port-security port-mode
command to restore the default
port security mode.
