NAME

Net::Packet::CDP::TypeAddresses - Cisco Discovery Protocol Addresses extension header

SYNOPSIS

    use Net::Packet::Consts qw(:cdp);
    require Net::Packet::CDP::TypeAddresses;
 
    # Build a layer
    my $layer = Net::Packet::CDP::TypeAddresses->new(
       type              => NP_CDP_TYPE_ADDRESSES,
       length            => 8,
       numberOfAddresses => 0,
       addresses         => [],
    );
    $layer->pack;
 
    print 'RAW: '.unpack('H*', $layer->raw)."\n";
 
    # Read a raw layer
    my $layer = Net::Packet::CDP::TypeAddresses->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 Addresses type extension header.

ATTRIBUTES

type - 16 bits
length - 16 bits
numberOfAddresses - 32 bits
addresses - variable length
The last one contains an arrayref of Net::Packet::CDP::Address objects.

METHODS

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

type: NP_CDP_TYPE_ADDRESSES

length: 8

numberOfAddresses: 0

addresses: []

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