   # Build a layer
   my $layer = Net::Packet::CDP::TypePortId->new(
      type        => NP_CDP_TYPE_PORT_ID,
      length      => 8,
      sentThrough => '1/4',
   );
   $layer->pack;

   print 'RAW: '.unpack('H*', $layer->raw)."\n";

   # Read a raw layer
   my $layer = Net::Packet::CDP::TypePortId->new(raw => $raw);

   print $layer->print."\n";
