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;

DESCRIPTION

This modules implements the encoding and decoding of the 802.1Q layer.

Details: http://standards.ieee.org/getieee802/802.1.html

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

ATTRIBUTES

priority: The priority field.
cfi: The cfi field. It is only one bit long, so set it to 0 or 1.
id: 8021Q tag id. You'll love it.
type: Which type the next encapsulated layer is.

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

raw
payload
nextLayer
