1. Interface - Selects the physical interface for which data is to be configured.
2. Use T
rust Mode to indicate whether the interface is trusted for Dynamic ARP Inspection
purpose. If this object is set to 'Enable', the interface is trusted. ARP packets coming to this
interface will be forwarded without checking. If this object is set to 'Disable', the interface is
not trusted. ARP packets coming to this interface will be subjected to ARP inspection. The
factory default is disable.
3. Use Rate Limit (pps) to specify 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 N/A there is no limit. The
value can set to -1, which means N/A. The range of Rate Limit is 0 - 300. The factory default
is 15pps (packets per second).
4. Use Burst Interval (secs) to specify the burst interval value for rate limiting purpose on this
interface. If the rate limit is None burst interval has no meaning shows it as N/A.
The factory
default is 1 second.
