Configure > Port
LABEL 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.
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.
