DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide 30-5 ip arp inspection limit This command is used to limit the rate of incoming ARP requests and responses on an interface. Use the no form of this command to revert to the default settings. ip arp inspection limit {rate VALUE [burst interval SECONDS] | none} no ip arp inspection limit Parameters rate VALUE burst interval SECONDS none Specifies the maximum number per second of the ARP packets that can be processed. The valid range is from 1 to 150 seconds. (Optional) Specifies the length of the burst duration of the ARP packets that is allowed. The valid range is from 1 to 15. If not specified, the default setting is one second. Specifies that there is no limit on the ARP packet rate. Default For DAI untrusted interfaces, the rate limit is 15 packets per second with a burst interval of 1 second. For DAI trusted interfaces, the rate has no limit. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline This command takes effect for both trusted and un-trusted interfaces. When the rate of the ARP packet per second exceeds the limitation and the condition sustained for the configured burst duration, the port will be put in the error disable state. Example This example shows how to limit the rate of the incoming ARP requests to 30 packets per second and to set the interface monitoring interval to 5 consecutive seconds.
