NAME

packet.link.vlan - VLAN module

DESCRIPTION

Decode Virtual LAN IEEE 802.1Q/802.1ad layer

CLASSES

class VLAN(baseobj.BaseObj)

VLAN object
Usage:
    from packet.link.vlan import VLAN
    x = VLAN(pktt)
Object definition:
VLAN(
    pcp   = int,  # Priority Point Code
    dei   = int,  # Drop Eligible Indicator
    vid   = int,  # VLAN Identifier
    etype = int,  # Payload Type
    psize = int,  # Payload Data Size
)

Methods defined here: ---------------------

__init__(self, pktt) Constructor

Initialize object's private data.

pktt:: Packet trace object (packet.pktt.Pktt) so this layer has access to the parent layers.

__str__(self) String representation of object

The representation depends on the verbose level set by debug_repr(). If set to 0 the generic object representation is returned. If set to 1 the representation of the object is condensed:
'802.1Q VLAN pcp: 4, dei: 0, vid: 2704 '

If set to 2 the representation of the object also includes the type of payload:
'802.1Q Virtual LAN, pcp: 4, dei: 0, vid: 2704, etype: 0x0800(IPv4)'

FUNCTIONS

vlan_layers(pktt)
Get all nested (stacked VLANs or QinQ) VLAN layers
A Packet layer attribute is created for each VLAN layer:
vlan1, vlan2, ..., and vlan. The last packet attribute
is always vlan.

BUGS

No known bugs.
