Displays and modifies the IP-to-Physical address translation
tables used by
address resolution protocol (ARP).
ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr]
-a Displays current ARP entries by
interrogating the current protocol data.
If inet_addr is specified, the IP and
Physical addresses for only the specified
computer are displayed. If more than one
network interface uses ARP, entries for
each ARP table are displayed.
-g Same as -a.
inet_addr Specifies an internet address.
-N if_addr Displays the ARP entries for the network
interface specified by if_addr.
-d Deletes the host specified by inet_addr.
inet_addr may be wildcarded with * to
delete all hosts.
-s Adds the host and associates the Internet
address inet_addr with the Physical address
eth_addr. The Physical address is given as
6 hexadecimal bytes separated by hyphens.
The entry is permanent.
eth_addr Specifies a physical address.
if_addr If present, this specifies the Internet
address of the interface whose address
translation table should be modified. If
not present, the first applicable interface
will be used.
Example:
> arp -s 157.55.85.212 00-aa-00-62-c6-09 .... Adds a
static entry.
> arp -a .... Displays the arp table.
