Description
Each page shows up to 99 entries from the Dynamic ARP Inspection table, default being 20,
selected through the "entries per page" input field. 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. This 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.
Switch Port Number for which the entries are displayed.
VLAN-ID in which the ARP traffic is permitted.
User MAC address of the entry.
