NAME
       arp - address resolution display and control

SYNOPSIS
       hostname

       [system]

       [system [core]]

       | hostname

       filename

       hostname hw_address rif_address]

       hostname nport_id

DESCRIPTION
       The  command  displays  and  modifies the Internet-to-Ethernet and Internet-to-Fibre Channel address translation tables used by the Address
       Resolution Protocol (ARP).

   Options
       has the following keyletter options:

	      hostname	Display the current ARP entry for hostname, which must appear in the hostname database (see hosts(4)), or  for	the  DARPA
			Internet address expressed in Internet standard ``dot'' notation.

	      Display all current
			ARP  entries  by reading the table from based on the kernel file system (default On PA systems only: if a core argument is
			supplied, read the table from core instead of The option provides the same information as the option except  that  network
			addresses are not displayed symbolically.

	      If an	ARP entry exists for the host called hostname, delete it. This option cannot be used to delete a permanent ARP entry whose
			IP address is an interface on the local system.

	      (Not recommended). Delete a permanent ARP entry whose IP
			address is an interface on the local system.  The removal of such an ARP entry may result in loss or limitation of network
			connectivity  with  remote  machines. The local system will no longer respond to ARP requests for this IP address.  Conse-
			quently, communication with remote systems is possible only when that communication is	initiated  by  the  local  system.
			This option should be used with extreme caution.

	      Read file filename and set multiple entries in the ARP tables.  Fibre Channel entries in the file should be of the form:

			Other entries in the file should be of the form:

			       hostname hw_address
			       rif_address]

			The argument meanings are the same as for the option.

	      Create an ARP  entry  for  the  host  called hostname with the hardware station address hw_address.  The hardware station address is
			given as six hexadecimal bytes separated by colons.  If an ARP entry already exists for hostname, the  existing  entry	is
			updated with the new information.

			The entry is permanent unless the word is given in the command.

			If  the  word  is  specified, the entry is published, which means that this system will act as an ARP server responding to
			requests for hostname even though the host address is not its own.

			The word specifies source routing information used for token ring networks.  This information allows you  to  specify  the
			particular  bridge route which the token ring packet should be delivered.  rif_address is given as an even number of hexa-
			decimal bytes separated by colons, up to a maximum of 16 bytes.

	      Create a permanent
			ARP entry for the Fibre Channel host called hostname with the N_Port address nport_id.	The N_Port  address  is  given	as
			three  hexadecimal  bytes separated by colons.	If an ARP entry already exists for hostname, the existing entry is updated
			with the new information.

       You need superuser privilege to use the and options.

       See the Neighbor Discovery Protocol (ndp(1M)) for IPv6.
