Configuring Intrusion Protection - HP 6125XLG Configuration Manual

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
To configure the NTK feature:

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.
