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 if the sender’s

 

information in the ARP packet does not match any of the current bindings.

 

 

Apply

Click Apply to save your changes to the Switch’s run-time memory. The

 

Switch loses these changes if it is turned off or loses power, so use the

 

Save link on the top navigation panel to save your changes to the non-

 

volatile memory when you are done configuring.

 

 

Cancel

Click this to reset the values in this screen to their last-saved values.
