Configuring IPv4 IMPB ARP Detection Configuration Follow these steps to configure ARP Detection on ports: 1) Select one or more ports and configure the parameters. Trust Status Limit Rate Enable or disable this port to be a trusted port. On a trusted port, the ARP packets are forwarded directly without checked. The specific ports, such as up-link ports and routing ports are suggested to be set as trusted. Specify the maximum number of the ARP packets that can be received on the port per second. Current Speed Displays the current speed of receiving the ARP packets on the port. Burst Interval Status Operation LAG 2) Click Apply. Specify a time range. If the speed of received ARP packets reaches the limit for this time range, the port will be shut down. Displays the status of the ARP attack: Normal: The forwarding of ARP packets on the port is normal. Down: The transmission speed of the legal ARP packet exceeds the defined value. The port will be shut down for 300 seconds. You can also click the Recovery button to recover If Status is changed to Down, there will be a Recover button. You can click the button to restore the port to the normal status. Displays the LAG that the port is in. 3.1.4 Viewing ARP Statistics You can view the number of the illegal ARP packets received on each port, which facilitates you to locate the network malfunction and take the related protection measures.
