Net::Packet::ETH - Ethernet/802.3 layer 2 object
use Net::Packet::ETH; use Net::Packet::Consts qw(:eth); # Build layer to inject to network my $eth1 = Net::Packet::ETH->new( type => NP_ETH_TYPE_IPv6, dst => "00:11:22:33:44:55", ); # Decode from network to create the object # Usually, you do not use this, it is used by Net::Packet::Frame my $eth2 = Net::Packet::ETH->new(raw => $rawFromNetwork); print $eth1->print, "\n";
This modules implements the encoding and decoding of the Ethernet/802.3 layer.
See also Net::Packet::Layer and Net::Packet::Layer2 for other attributes and methods.
Source and destination MAC addresses, in classical format (00:11:22:33:44:55).
The encapsulated layer type (IPv4, IPv6 ...) for Ethernet. Values for Ethernet types are greater than 1500. If it is less than 1500, you should use the length attribute (which is an alias of this one), because the layer is considered a 802.3 one. See http://www.iana.org/assignments/ethernet-numbers .
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).
Object constructor. You can pass attributes that will overwrite default ones. Default values:
src: $Env->mac (see Net::Packet::Env)
Packs all attributes into a raw format, in order to inject to network. Returns 1 on success, undef otherwise.
Unpacks raw data from network and stores attributes into the object. Returns 1 on success, undef otherwise.
- isTypeIp - is type IPv4 or IPv6
Helper methods. Return true is the encapsulated upper layer is of specified type, false otherwise.
Load them: use Net::Packet::Consts qw(:eth);
Ethernet header length in bytes.
Ethernet broadcast address.
Various supported Ethernet types.
