4.10.2.6.4 Network ARP Inspection Dynamic Table Configuration

Entries in the Dynamic ARP Inspection table are shown on the Dynamic ARP Inspection Table page. The Dynamic ARP Inspection table contains up to 256 entries, and is sorted in the following order:

  1. Port
  2. VLAN ID
  3. MAC address
  4. IP address

All Dynamic ARP Inspection Table dynamic entries learn from DHCP Snooping. Each page shows up to 99 entries from the Dynamic ARP Inspection table, default being 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 Refresh 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 Refresh button click - assume the value of the first displayed entry, allowing for continuous refresh with the same start address. The >> 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.
