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