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.
