Enter the VLAN IDs you want the Switch to enable ARP
Inspection for. You can designate multiple VLANs individually by
using a comma (,) and by range with a hyphen (-).
Select the ports which are trusted and deselect the ports which
are 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.
