the Go button.
• Next to the Interface column, select the check box for the port that you want to

6. Use T
rust Mode to indicate whether the interface is trusted for dynamic ARP inspection
purposes.
If this is set to Enable, the interface is trusted. ARP packets coming to this interface are
forwarded without checking. If this is set to Disable, the interface is not trusted.
ARP
packets coming to this interface are subjected to ARP inspection. The factory default is
Disable.
7. 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 for consecutive burst
interval seconds,
ARP packets are dropped. If this value is N/A, there is no limit. The
value can be set to –1, which means N/A. The range is 0– 300. The factory default is 15
pps (packets per second).
8. Use Burst Interval (secs) to specify the burst interval value for rate limiting purposes on this
interface. If the rate limit is None, burst interval has no meaning and is displayed as N/A.
The Rate Limit range is 1 to 15.
The factory default is 1 second.
9. Click the Apply button.
