ARP Table

With the ARP Table page, you can:

• Display or remove all addresses in Address Resolution Protocol (ARP) Table.
• Set the ARP cache timeout value.

ARP discovers the MAC addresses that correspond to the IP address for a given host.

Displaying and Removing Addresses in the ARP Table

The Current ARP Table maps the IP address to the MAC address and shows the VLAN ID. For example, a table entry of "Internet 171.71.93.161 186 0000.0c07.ac01 ARPA VLAN1" means:

To clear all entries from the table, click Remove All.

Note: You can manually add entries to the ARP table from the command-line interface; however, entries added manually do not age and must be manually removed.

Setting the ARP Cache Timeout Value

You can specify the amount of time before ARP entries are aged and removed from the ARP table.

To change the ARP timeout value:

1. In the ARP Cache Timeout Value field, enter a number from 1 to 4294967.
   The default value is 14400 seconds.
2. Click Apply.
