Chapter 16: Managing ARP Traffic
Network > ARP
ARP (Address Resolution Protocol) maps layer 3 (IP addresses) to layer 2 (physical or MAC
addresses) to enable communications between hosts residing on the same subnet. ARP is a
broadcast protocol that can create excessive amounts of network traffic on your network. To minimize
the broadcast traffic, an ARP cache is maintained to store and reuse previously learned ARP
information.
Navigating and Sorting the ARP Cache Table Entries
The ARP Cache tabe table provides easy pagination for viewing a large number of ARP entries. You
can navigate a large number of ARP entries listed in the ARP Cache table by using the navigation
control bar located at the top right of the ARP Cache table. Navigation control bar includes four
buttons. The far left button displays the first page of the table. The far right button displays the last
page. The inside left and right arrow buttons moved the previous or next page respectively.
You can enter the policy number (the number listed before the policy name in the # Name column) in
the Items field to move to a specific ARP entry. The default table configuration displays 50 entries per
page. You can change this default number of entries for tables on the System>Administration page.
