ARP - Address Resolution Protocol

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] 

key
   -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 157.55.85.212   00-aa-00-62-c6-09  .... Adds a static entry.
  > arp -a                                    .... Displays the arp table.
