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 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.
On a port operating in either the macAddressElseUserLoginSecure mode or the
macAddressElseUserLoginSecureExt mode, intrusion protection is triggered only after both MAC
authentication and 802.1X authentication fail for the same frame.
