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-PS) on Ethernet-like interfaces. Normally
there is no need to add entries to the table with arp add, since they should be
discovered by the ARP protocol. Displaying the table with arp list (or just arp) is
sometimes useful, and deleting an entry with arp delete, or the whole table with arp
flush, 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).
