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.
With the NTK feature, 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

Remarks
N/A
By default, no OUI value is
configured for user authentication.
This command is required for the
userlogin-withoui mode.
You can set multiple OUIs, but
when the port security mode is
userlogin-withoui, the port allows
one 802.1X user and only one user
that matches one of the specified
OUIs.
•
To specify the autoLearn mode,
you must enter Ethernet
interface view.
•
To specify the
userloginWithOUI mode, you
must enter Ethernet interface
view or WLAN-ESS 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.
