NAME

Net::Frame::Layer::MPLS::PWACH - MPLS Pseudowire Associated Channel Header layer object

SYNOPSIS

use Net::Frame::Simple;
use Net::Frame::Layer::MPLS::PWACH qw(:consts);

my $layer = Net::Frame::Layer::MPLS::PWACH->new(
   pwNibble    => NF_MPLS_PWNIBBLE_ACH,
   version     => 0,
   reserved    => 0,
   channelType => NF_MPLS_PWACHTYPE_IPv4,
);

#
# Read a raw layer
#

my $layer = Net::Frame::Layer::MPLS::PWACH->new(raw => $raw);

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