• If you are configuring the autoLearn mode, set port security's limit on the number of secure
MAC addresses. You cannot change the setting when the port is operating in autoLearn mode.
When you set the port security mode, follow these guidelines:
• You can specify a port security mode when port security is disabled, but your configuration
cannot take effect.
• Changing the port security mode of a port logs off the online users of the port.
• Do not enable 802.1X authentication or MAC authentication on a port where port security is
configured.
To enable a port security mode:
Step
Command
Remarks
1. Enter system view.

2. (Optional.) Set an OUI value
for user authentication.
port-security oui index
index-value
mac-address
oui-value
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.
3. Enter

By default, a port oper
ates 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.
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.
