DESCRIPTION
Port
This field displays the port number. If you configure the
*
port, the settings are
applied to all of the ports.
*
Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this
row first to set the common settings and then make adjustments on a port-by-port
basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Trusted State
Select whether this port is a trusted port (
Trusted
) or an untrusted port
(
Untrusted
).
The Switch does not discard ARP packets on trusted ports for any reason.
The Switch discards ARP packets on untrusted ports in the following situations:
•
The sender’s information in the ARP packet does not match any of the current
bindings.
•
The rate at which ARP packets arrive is too high. You can specify the maximum
rate at which ARP packets can arrive on untrusted ports.
Limit
These settings have no effect on trusted ports.
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.
