Managing ARP Traffic
You can sort the entries in the table by clicking on the column header. The entries are sorted by
ascending or descending order. The arrow to the right of the column entry indicates the sorting status.
A down arrow means ascending order. An up arrow indicates a descending order.
Flushing the ARP Cache
It is sometimes necessary to flush the ARP cache if the IP address has changed for a device on the
network. Since the IP address is linked to a physical address, the IP address can change but still be
associated with the physical address in the ARP Cache. Flushing the ARP Cache allows new
information to be gathered and stored in the ARP Cache. Click Flush ARP Cache to clear the
information.
To configure a specific length of time for the entry to time out, enter a value in minutes in the ARP
Cache entry time out (minutes) field.
