The need to know (NTK) feature checks the destination MAC addresses in outbound frames to allow
frames to be sent to only devices passing authentication, thus preventing illegal devices from
intercepting network traffic.

Examples
# Set the NTK mode of port GigabitEthernet 1/0/1 to
ntkonly
, allowing the port to forward received
packets to only devices passing authentication.

Default Level
2: System level
Parameters
oui-value
: Organizationally unique identifier (OUI) string, a 48-bit MAC address in the H-H-H format.
The system automatically uses only the 24 high-order bits as the OUI value.
index-value
: OUI index, in the range 1 to 16.
Description
Use the
port-security oui
command to configure an OUI value for user authentication. This value is
used when the port security mode is UserLoginWithOUI.
Use the
undo port-security oui
command to delete an OUI value with the specified OUI index.
By default, no OUI value is configured.
Note that an OUI value configured by using the
port-security oui
command takes effect only when the
security mode is userLoginWithOUI.

Examples
# Configure an OUI value of 000d2a, setting the index to 4.
