Net::Frame::Layer::ETH(3) User Contributed Perl Documentation Net::Frame::Layer::ETH(3)

Net::Frame::Layer::ETH - Ethernet/802.3 layer object

   use Net::Frame::Layer::ETH qw(:consts);

   # Build a layer
   my $layer = Net::Frame::Layer::ETH->new(
      src  => '00:00:00:00:00:00',
      dst  => NF_ETH_ADDR_BROADCAST,
      type => NF_ETH_TYPE_IPv4,
   );
   $layer->pack;

   print 'RAW: '.$layer->dump."\n";

   # Read a raw layer
   my $layer = Net::Frame::Layer::ETH->new(raw => $raw);

   print $layer->print."\n";
   print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"
      if $layer->payload;

This modules implements the encoding and decoding of the Ethernet/802.3 layer.

RFC: ftp://ftp.rfc-editor.org/in-notes/rfc894.txt

See also Net::Frame::Layer for other attributes and methods.

src
dst
Source and destination MAC addresses, in classical format (00:11:22:33:44:55).
type
The encapsulated layer type (IPv4, IPv6 ...) for Ethernet. Values for Ethernet types are greater than 1500. If it is less than 1500 the layer is considered a 802.3 one. See http://www.iana.org/assignments/ethernet-numbers .
length
The length of the payload when this layer is a 802.3 one. This is the same attribute as type, but you cannot use it when calling new (you can only use it as an accessor after that).

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

raw
payload
nextLayer

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

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

computeLengths
computeChecksums
pack
unpack
