Table 91 ARP Inspection Port Configure (continued)

LABEL	DESCRIPTION
Burst interval	The burst interval is the length of time over which the rate of ARP
(seconds)	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.
