ntk-withmulticasts—Forwards only broadcast frames, multicast frames, and unicast frames with

all port security modes support triggering the NTK feature. For more information, see
To configure the NTK feature:
Step

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 addresses list
and discards the frames. All subsequent frames sourced from a blocked MAC address are dropped.
A blocked MAC address is restored to normal state after being blocked for 3 minutes. The interval
is fixed and cannot be changed.
disableport—Disables the port until you bring it up manually.
disableport-temporarily—Disables the port for a specific period of time. The period can be
configured with the port-security timer disableport command.
To configure the intrusion protection feature:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Configure the intrusion
protection feature.
4.
Return to system view.
5.
(Optional.) Set the silence
timeout period during which a
port remains disabled.
NOTE:
On a port operating in either macAddressElseUserLoginSecure mode or
macAddressElseUserLoginSecureExt mode, intrusion protection is triggered only after both MAC
authentication and 802.1X authentication fail for the same frame.
