The System Information page displays.

Select Security > Control > Dynamic ARP Inspection > DAI Interface Configuration.

Use one of the following methods to select an interface:

In the Go To Interface field, enter the interface in the unit/slot/port format and click on 
the Go button.

Next to the Interface column, select the check box for the port that you want to 
configure, select multiple check boxes to apply the same setting to all selected 
interfaces, or select the check box in the table heading to apply the same settings to 
all interfaces.

Use Trust 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.

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).

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.

Click the Apply button.

The updated configuration is sent to the switch. Configuration changes take effect 
immediately.
