NAME ^

Net::Frame::Layer::8021Q - 802.1Q layer object

SYNOPSIS ^

   use Net::Frame::Layer::8021Q qw(:consts);

   # Build a layer
   my $layer = Net::Frame::Layer::8021Q->new(
      priority => 0,
      cfi      => 0,
      id       => 0,
      type     => NF_8021Q_TYPE_IPv4,
   );
   $layer->pack;

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

   # Read a raw layer
   my $layer = Net::Frame::Layer::8021Q->new(raw => $raw);

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