NAME

Net::Frame::Layer::LLTD - Link Layer Topology Discovery layer object

SYNOPSIS

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

   # Build a layer
   my $layer = Net::Frame::Layer::LLTD->new(
      version         => 1,
      tos             => NF_LLTD_TOS_TOPOLOGY_DISCOVERY,
      reserved        => 0,
      function        => NF_LLTD_FUNCTION_DISCOVER,
      networkAddress1 => 'ff:ff:ff:ff:ff:ff',
      networkAddress2 => 'ff:ff:ff:ff:ff:ff',
      identifier      => getRandom16bitsInt(),
   );
   $layer->pack;

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

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

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