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.
