This command is used to display and modify the internet to ethernet address translation tables used by the address resolution protocol.

Options

Options and option parameters that are underlined indicate that a value must be specified for that option or parameter. For example, the arp command option -d has the parameter IP address. The IP address must be specified for which an ARP entry will be deleted, as in the command arp -d 192.9.200.44. Do not enter the underlined option or parameter; enter a value for the information represented by the underlined option or parameter.

This option displays all entries in the ARP table.

This option deletes an ARP entry for the specified IP address.

The IP address is a TCP/IP address expressed in standard “dot notation.” IP addresses consist of the system’s network number and the machine’s unique host number. An example IP address is 192.9.200.44, where 192.9.200 is the network number and 44 is the machine’s host number.

Range:

4 numbers separated by dots, with each number in the range of 0-255.

This option flushes all entries from the ARP table.

This option displays help (usage) information for the command.

This option creates an ARP entry for the specified IP address and ethernet address.

Range:

4 numbers separated by dots, with each number in the range of 0-255.

The IP address is a TCP/IP address expressed in standard “dot notation.” IP addresses consist of the system’s network number and the machine’s unique host number. For example, 192.9.200.44, where 192.9.200 is the network number and 44 is the machine’s host number.

Range:

6 hexadecimal numbers separated by colons; each number in the range 0 - FF.

The MAC (media access control) address is an ethernet address with the format x:x:x:x:x:x, where x is a hexadecimal integer from 0 to FF. For example, 08:00:20:1b:0f:f2.

Example

arp -a

arp -s 192.9.200.44 08:00:20:1b:0f:f2

arp -d 192.9.200.44

arp -f

Dependencies

Only one of the options can be specified at a time.

The arp command with no options displays all of the current ARP cache entries.

Notes

The arp command is executed through the pass command.
