Display and modify the IP-to-Physical address translation tables used by address resolution protocol.
syntax View the contents of the local ARP cache table ARP -a [ip_addr] [-N if_addr] Add a static Arp entry for frequent accessed hosts ARP -s ip_addr eth_addr [if_addr] Delete an entry ARP -d ip_addr [if_addr]
-a Display current ARP entries. May include more than one network interface. If ip_addr is specified, the IP and Physical addresses for only the specified computer are displayed. -g Same as -a. -N if_addr Display the ARP entries for the network interface specified by if_addr. -d ip_addr Delete the host specified by ip_addr. -d * will delete all hosts. -s Add the host and associates the Internet address ip_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 188.8.131.52 00-aa-00-62-c6-09 .... Adds a static entry. > arp -a .... Displays the arp table.
