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. Command system-view 2.
