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

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)'
