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;
