DESCRIPTION
This field displays the port number. If you configure the * port, the settings are applied to all
of the ports.
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.
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.
