for. You can designate multiple VLANs individually by using a
comma (,) and by range with a hyphen (-).
Trusted Ports 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.
