166 ATMOS Console Commands Reference Manual (Binary) DO-008530-PS, Draft B (26th April 2001)
12.3 arp
12.3.1 Syntax
arp add <i/f> <IP address> <MAC address>
arp delete <i/f> <IP address>
arp flush
arp [list]
arp help [all|<cmd>]
12.3.2 Description
Allows display and manipulation of the ARP table: the list of IP
addresses and corresponding MAC addresses obtained by ARP 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).
