NAME

Net::Packet::CDP::Address - Cisco Discovery Protocol Address format

SYNOPSIS

use Net::Packet::Consts qw(:cdp);
require Net::Packet::CDP::Address;

# Build a layer
my $layer = Net::Packet::CDP::Address->new(
   protocolType   => NP_CDP_ADDRESS_PROTOCOL_TYPE_NLPID,
   protocolLength => NP_CDP_ADDRESS_PROTOCOL_LENGTH_NLPID,
   protocol       => NP_CDP_ADDRESS_PROTOCOL_IP,
   addressLength  => NP_CDP_ADDRESS_ADDRESS_LENGTH_IP,
   address        => '127.0.0.1',
);
$layer->pack;

print 'RAW: '.unpack('H*', $layer->raw)."\n";

# Read a raw layer
my $layer = Net::Packet::CDP::Address->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 Cisco Discovery Protocol Address format.

ATTRIBUTES

protocolType - 8 bits

protocolLength - 8 bits

protocol - 8 bits

addressLength - 16 bits

address - 32 bits

METHODS

new

Object constructor. You can pass attributes that will overwrite default ones. Default values:

protocolType: NP_CDP_ADDRESS_PROTOCOL_TYPE_NLPID

protocolLength: NP_CDP_ADDRESS_PROTOCOL_LENGTH_NLPID

protocol: NP_CDP_ADDRESS_PROTOCOL_IP

addressLength: NP_CDP_ADDRESS_ADDRESS_LENGTH_IP

address: '127.0.0.1'

pack

Packs all attributes into a raw format, in order to inject to network. Returns 1 on success, undef otherwise.

unpack

Unpacks raw data from network and stores attributes into the object. Returns 1 on success, undef otherwise.

CONSTANTS

NP_CDP_ADDRESS_PROTOCOL_TYPE_NLPID

NP_CDP_ADDRESS_PROTOCOL_LENGTH_NLPID

NP_CDP_ADDRESS_PROTOCOL_IP

NP_CDP_ADDRESS_ADDRESS_LENGTH_IP

See also Net::Packet::CDP for other CONSTANTS.
