NAME

Net::Frame::Layer::LLC - Logical-Link Control layer object

SYNOPSIS

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

   # Build a layer
   my $layer = Net::Frame::Layer::LLC->new(
      dsap    => NF_LLC_DSAP_SNAP,
      ig      => 1,
      ssap    => NF_LLC_SSAP_SNAP,
      cr      => 1,
      control => 0x03,
   );
   $layer->pack;

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

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

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