Chapter 25 IP Source Guard Table 76 ARP Inspection Port Configure (continued) LABEL Limit Rate (pps) Burst interval (seconds) DESCRIPTION These settings have no effect on trusted ports. 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. 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. Apply Cancel Enter the length (1-15 seconds) of the burst interval. 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. Click this to reset the values in this screen to their last-saved values. 25.7.2 ARP Inspection VLAN Configure 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.
