NAME

Net::Frame::Layer::CDP::Address - Address encoding for CDP addresses TLV

SYNOPSIS

   use Net::Frame::Simple;
   use Net::Frame::Layer::CDP qw(:consts);

   my $layer = Net::Frame::Layer::CDP::Address->new(
      protocolType   => NF_CDP_ADDRESS_PROTOCOL_TYPE_NLPID,
      protocolLength => 1,
      protocol       => NF_CDP_ADDRESS_PROTOCOL_IP,
      addressLength  => 4,
      address        => '127.0.0.1',
   );

   #
   # Read a raw layer
   #
   my $layer = Net::Frame::Layer::CDP->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 addresses for the Addresses and ManagementAddresses CDP message type.

ATTRIBUTES

protocolType

Protocol type. See CONSTANTS for values.

protocolLength

Length of protocol value.

protocol

Protocol value. This is a pack('H*', $string) where $string represents the protocol. See CONSTANTS for values.

addressLength

Length of address.

address

Address.

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

raw

payload

nextLayer

METHODS

new

new (hash)

Object constructor. You can pass attributes that will overwrite default ones. See SYNOPSIS for default values.

ipv4Address

ipv4Address (hash)

Alias to new.

ipv6Address

ipv6Address (hash)

Alias to new.

Object constructor for IPv6 specific address.

      protocolType   => NF_CDP_ADDRESS_PROTOCOL_TYPE_8022,
      protocolLength => 8,
      protocol       => NF_CDP_ADDRESS_PROTOCOL_IPv6,
      addressLength  => 16,
      address        => '::1',

The following are inherited methods. Some of them may be overriden in this layer, and some others may not be meaningful in this layer. See Net::Frame::Layer for more information.
