Configuring NTK

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.

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
noRestriction mode.
After enabling port security, you
can change the port security mode
of a port only when the port is
operating in noRestriction (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.
