Configuring Intrusion Protection; Enabling Port Security Traps - HP 6125G Configuration Manual

ntk-withmulticasts—Forwards only broadcast frames, multicast frames, and unicast frames with
•
authenticated destination MAC addresses.
To configure the NTK feature:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
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 will be
dropped. A blocked MAC address is restored to normal state after being blocked for three 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.
On a port
macAddressElseUserLoginSecureExt mode, intrusion protection is triggered only after both MAC
authentication and 802.1X authentication for the same frame fail.
To configure the intrusion protection feature:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view.
3. Configure the intrusion
protection feature.
4. Return to system view.
5. Set the silence timeout period
during which a port remains
disabled.

Enabling port security traps

You can configure the port security module to send traps for the following categories of events:
addresslearned—Learning of new MAC addresses.
