Field Description
Interface Select the physical interface for which data is to be displayed or configured.
Trust State 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.
Rate Limit Specifies rate limit value for Dynamic ARP Inspection purpose. If the incoming rate of ARP
packets exceeds the value of this object for consecutively burst interval seconds, ARP
packets will be dropped. If this value is -1 there is no limit. The Range is (0 to 300 pps). The
factory default is 15pps (packets per second).
No Limit Selecting this option specifies that the value of Rate Limit will be configured to -1. If the
rate limit is -1 burst interval has no meaning , hence it is disabled.
Burst Interval 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). The default is 1 second.
