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 Inter‐
       net-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 stan‐
			dard ``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  dis‐
			played 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.  Consequently,  com‐
			munication  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 hard‐
			ware 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 informa‐
			tion.

			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 hexadecimal  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 informa‐
			tion.

       You need superuser privilege to use the and options.

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