10.3 arp

10.3.1 Syntax

arp add <i/f> <IP address> <MAC address>

arp delete <i/f> <IP address>

arp flush

arp [list]

arp help [all|<cmd>]

10.3.2 Description

Allows display and manipulation of the ARP table: the list of IP addresses and

corresponding MAC addresses obtained by ARP (see the

ATMOS TCP/IP

Functional Specification, DO-007285-P

S) on Ethernet-like interfaces. Normally

there is no need to add entries to the table with

arp ad

d, since they should be

discovered by the ARP protocol. Displaying the table with

arp list

(or just

p) is

sometimes useful, and deleting an entry with

arp delet

e, or the whole table with

arp

flus

h, can sometimes speed up recovery from temporary problems if something

unusual has happened.
Entries added with

arp add

do not time out like those discovered by use of the ARP

protocol, but they are deleted by

arp flush

and will not survive a restart (they are not

saved by configuration saving).
Note that the ARP table is used only for destinations on directly connected
Ethernet-like networks, not for those reached through routers (although the ARP
table may be used to discover the MAC address of the router).
