NAME

Net::Packet::PPPLCP - PPP Link Control Protocol layer 3 object

SYNOPSIS

    use Net::Packet::Consts qw(:ppplcp);
    require Net::Packet::PPPLCP;
 
    # Build a layer
    my $layer = Net::Packet::PPPLCP->new(
       code        => NP_PPPLCP_CODE_ECHO_REQUEST,
       identifier  => 1,
       length      => NP_PPPLCP_HDR_LEN,
       magicNumber => 0xffffffff,
    );
    $layer->pack;
 
    print 'RAW: '.unpack('H*', $layer->raw)."\n";
 
    # Read a raw layer
    my $layer = Net::Packet::PPPLCP->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 PPP Link Control Protocol layer.

See also Net::Packet::Layer and Net::Packet::Layer3 for other attributes and methods.

ATTRIBUTES

code - 8 bits
identifier - 8 bits
length - 16 bits
magicNumber - 32 bits

METHODS

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

code: NP_PPPLCP_CODE_ECHO_REQUEST

identifier: 1

length: NP_PPPLCP_HDR_LEN

magicNumber: 0xffffffff

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
