State

Use this to Enable or Disable ARP inspection on the Switch.

VLAN State

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 (-).

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. 

Select All

Click this to set all ports to trusted.
