Use this screen to enable ARP inspection on each VLAN and to specify when the 
Switch generates log messages for receiving ARP packets from each VLAN. To 
open this screen, click Advanced Application > IP Source Guard > ARP 
Inspection > Configure > VLAN.

Figure 128   ARP Inspection VLAN Configure

The following table describes the labels in this screen.

Burst interval 
(seconds)

The burst interval is the length of time over which the rate of ARP 
packets is monitored for each port. For example, if the Rate is 15 
pps and the burst interval is 1 second, then the Switch accepts a 
maximum of 15 ARP packets in every one-second interval. If the 
burst interval is 5 seconds, then the Switch accepts a maximum of 
75 ARP packets in every five-second interval.

Enter the length (1-15 seconds) of the burst interval.

Apply

Click Apply to save your changes to the Switch’s run-time memory. 
The Switch loses these changes if it is turned off or loses power, so 
use the Save link on the top navigation panel to save your changes 
to the non-volatile memory when you are done configuring.

Cancel

Click this to reset the values in this screen to their last-saved 
values.
