# ARP Table

Device>Configure>ARP Table

Many types of data transmission (for example, on a LAN or a packet network) require information that provides physical address information for corresponding IP addresses.

ARP (Address Resolution Protocol) dynamically discovers the corresponding physical address for a known IP address. This process is called IP-to-physical-address mapping, and the information is stored in a table called the Address Translation Table or the ARP table. This information is required for various types of data transmission.

The ARP table can also include your manual entries.

The following information is displayed in the ARP Table window:

Interface (ipNetToMediaIfIndex)

Index value of this interface from the Interface table.

Network Address (ipNetToMediaNetAddress)

IP address for which the corresponding physical address is displayed.

Physical Address (ipNetToMediaPhysAddress)

Physical address that is mapped to the IP address.

Type (ipNetToMediaType)

How the entry was learned. Possible values are dynamic, static, other, or invalid. Use the invalid value to remove the entry from the table.

Click Create to create a new row in the ARP table (enter an Interface index number, a Network IP address, and a Physical Address, then click Apply), or click Delete to remove the currently selected row.

Click Apply to make your changes take effect, or click Cancel to close the dialog box without making any changes. Click Print to print the contents of the dialog box.
