The following table describes the labels in this screen.
Rate (pps) Specify the maximum rate (1-2048 packets per second) at which the Switch
receives ARP packets from each port. The Switch discards any additional ARP
packets. Enter 0 to disable this limit.
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.
