NAME
Net::Packet::VLAN - 802.1Q layer 3 objectSYNOPSIS
use Net::Packet::Consts qw(:vlan); require Net::Packet::VLAN; # Build a layer my $layer = Net::Packet::VLAN->new( priority => 0, cfi => 0, id => 0, type => NP_VLAN_TYPE_IPv4, ); $layer->pack; print 'RAW: '.unpack('H*', $layer->raw)."\n"; # Read a raw layer my $layer = Net::Packet::VLAN->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 Virtual LAN/802.1Q layer.Details: http://standards.ieee.org/getieee802/802.1.html
See also Net::Packet::Layer and Net::Packet::Layer3 for other attributes and methods.
ATTRIBUTES
- priority
- The priority field.
- cfi
- The cfi field. It is only one bit long, so set it to 0 or 1.
- id
- VLAN tag id. You'll love it.
- type
- Which type the next encapsulated layer is.
- frame
- This is a Net::Packet::Frame object, built it like any other such frame. Just to mention that you should use dnoFexLien attribute if you put in a Net::Packet::IPv4 layer.
METHODS
- new
- Object constructor. You can pass attributes that will overwrite default ones. Default values:
priority: 0
cfi: 0
id: 0
type: NP_VLAN_TYPE_IPv4
- 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.
- isTypeArp
- isTypeIpv4
- isTypeIpv6
- isTypeIp - is type IPv4 or IPv6
- isTypeVlan
- Helper methods. Return true is the encapsulated layer is of specified type, false otherwise.
CONSTANTS
Load them: use Net::Packet::Consts qw(:vlan);- NP_VLAN_TYPE_ARP
- NP_VLAN_TYPE_IPv4
- NP_VLAN_TYPE_IPv6
- NP_VLAN_TYPE_VLAN
- Various supported encapsulated frame types.
