NAME

Net::Packet::Ethernet

SYNOPSIS

use Net::Packet::Ethernet :short;

my $frame = Buf.new([...]);
my $eth = Ethernet.decode($frame);

say sprintf '%s -> %s: %s',
    $eth.src.Str, $eth.src.Str, $eth.type;

Prints: 66:77:88:99:AA:BB -> 66:77:88:99:AA:BB: IPv4

EXPORTS

Net::Packet::Ethernet

:short trait adds exports:

constant Ethernet  ::= Net::Packet::Ethernet;
constant MAC_addr  ::= Net::Packet::MAC_addr;
constnat EtherType ::= Net::Packet::EtherType;

DESCRIPTION

Net::Packet::Ethernet takes a byte buffer and returns a corresponding packet object. The byte buffer can be of the builtin Buf type or the C_Buf type of Net::Pcap.

class Net::Packet::Ethernet

is Net::Packet::Base;

Attributes

 $.src         is rw is Net::Packet::Ethernet::MAC_addr
$.dst         is rw is Net::Packet::Ethernet::MAC_addr
  Source/destination MAC address

$.type        is rw is Net::Packet::Ethernet::EtherType
  Payload type.

$.is_802_1Q   is rw is Bool
  Set if packet is of type IEE802.1Q.

$.pcp         is rw is Int
$.dei         is rw is Int
$.vid         is rw is Int
  PCP/DEI/VID field. Only used if $.is_802_1Q is set.

$.is_802_1ad  is rw is Bool
  Set if packet is of type IEEE802.1ad.

$.s-vid       is rw is Int
$.s-dei       is rw is Int
$.s-pcp       is rw is Int
  PCP/DEI/VID field of the service provider. Only used if IEEE802.1ad is set.

Methods

.decode($frame, Net::Packet::Base $parent?) returns Net::Packet::Ethernet
  Returns the Ethernet packet corresponding to $frame.

.encode()
  Writes the packet to $.frame buffer, including the payload.

.pl() returns Proxy is rw
  Returns a Proxy for the payload of this packet.
  Usage:
    $eth.pl = ...
    my $ip = $eth.pl.
