Parameter description:
Navigating the ARP Inspection Table:
Each page shows up to 99 entries from the Dynamic ARP Inspection table, default is 20, selected through the “entries per page” input
field. When first visited, the web page will show the first 20 entries from the beginning of the Dynamic ARP Inspection Table.
The “Start from port address”, “VLAN”, “MAC address” and “IP address” input fields allow the user to select the starting point in the
Dynamic ARP Inspection Table. Clicking the button will update the displayed table starting from that or the closest next Dynamic
ARP Inspection Table match. In addition, the two input fields will—upon a button click—assume the value of the first displayed entry,
allowing for continuous refresh with the same start address.
The switch will use the last entry of the currently displayed table as a basis for the next lookup. When the end is reached, the text “No
more entries” is shown in the displayed table. Use the button to start over.
