| Displays and modifies the IP-to-Physical address translation tables used by address resolution protocol (ARP). ARP -s inet_addr eth_addr [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. |
| -v | Displays current ARP entries in verbose mode. All invalid entries and entries on the loop-back interface will be shown. |
| 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. |
