Figure 132: Dynamic ARP Inspection Interface Configuration Field Slot/Port Trust State Rate Limit Burst Interval Table 115: Dynamic ARP Inspection Interface Configuration Description Select the physical interface for which data is to be displayed or configured. Indicates whether the interface is trusted for Dynamic ARP Inspection. If you select Enable, the interface is trusted. ARP packets coming to this interface will be forwarded without checking. If you select Disable, the interface is not trusted. ARP packets coming to this interface will be subjected to ARP inspection. The default is Disable. Specify the rate limit value for Dynamic ARP Inspection. If the incoming rate exceeds the Rate Limit value for consecutively burst interval seconds, ARP packets will be dropped. If the value is None, there is no limit. The default is 15 packets per second (pps). Specify the burst interval for rate limiting on this interface. If the Rate Limit is None, then Burst Interval has no meaning and shows as N/A (Not Applicable).
