NAME

       Net::Frame::Layer::ARP - Address Resolution Protocol layer object

SYNOPSIS

          use Net::Frame::Layer::ARP qw(:consts);

          # Build a layer
          my $layer = Net::Frame::Layer::ARP->new(
             hType   => NF_ARP_HTYPE_ETH,
             pType   => NF_ARP_PTYPE_IPv4,
             hSize   => NF_ARP_HSIZE_ETH,
             pSize   => NF_ARP_PSIZE_IPv4,
             opCode  => NF_ARP_OPCODE_REQUEST,
             src     => '00:00:00:00:00:00',
             dst     => NF_ARP_ADDR_BROADCAST,
             srcIp   => '127.0.0.1',
             dstIp   => '127.0.0.1',
          );
          $layer->pack;

          print 'RAW: '.$layer->dump."\n";

          # Read a raw layer
          my $layer = Net::Frame::Layer::ARP->new(raw => $raw);

          print $layer->print."\n";
          print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"
             if $layer->payload;

DESCRIPTION

       This modules implements the encoding and decoding of the ARP layer.

       RFC: ftp://ftp.rfc-editor.org/in-notes/rfc826.txt

       See also Net::Frame::Layer for other attributes and methods.

ATTRIBUTES

       hType
       pType
           Hardware and protocol address types.

       hSize
       pSize
           Hardware and protocol address sizes in bytes.

       opCode
           The operation code number to perform.

       src
       dst Source and destination hardware addresses.

       srcIp
       dstIp
           Source and destination IP addresses.

       The following are inherited attributes. See Net::Frame::Layer for more information.

       raw
       payload
       nextLayer

METHODS

       new
       new (hash)
           Object constructor. You can pass attributes that will overwrite default ones. See
           SYNOPSIS for default values.

       getKey
       getKeyReverse
           These two methods are basically used to increase the speed when using recv method from
           Net::Frame::Simple. Usually, you write them when you need to write match method.

       match (Net::Frame::Layer::ARP object)
           This method is mostly used internally. You pass a Net::Frame::Layer::ARP layer as a
           parameter, and it returns true if this is a response corresponding for the request, or
           returns false if not.

       The following are inherited methods. Some of them may be overridden in this layer, and
       some others may not be meaningful in this layer. See Net::Frame::Layer for more
       information.

       layer
       computeLengths
       computeChecksums
       pack
       unpack
       encapsulate
       getLength
       getPayloadLength
       print
       dump
