Description: This attribute is used to specify a set of VLAN IDs
against which the traffic being classified is compared.
Packets that contain a VLAN ID equal to one of the VLAN 
IDs in this set match this component of an 802 filter.

The format of this octet string is a series of two-byte
(16 bit) values with each octet tuple identifying a
single VLAN ID in the set. Therefore, the length of the
octet string value of this object is always either zero
or an even number of octets (e.g., 2, 4, 6, 20). As with
most sets, ordering within the set (octet string) is
unimportant. For example, a set specifying three VLAN 
IDs (8, 35 and 4012) might be specified as follows:

   Octets:   1   |  2   |  3   |  4   |  5   |  6
   ------------------------------------------------
   Values:  0x00 | 0x23 | 0x00 | 0x08 | 0x0F | 0xAC 
   ------------------------------------------------
   VLAN ID:     35      |      8      |    4012  

The supported maximum length of this attribute depends
on the maximum number of VLANs that may be included in
a set for filtering purposes. This length is thus
implementation dependent.

Note that this attribute and the qos802AceVlanId
attribute are mutually exclusive. The value of the
qos802AceVlanId component of the augmented filter
entry must be set to 'ignore' (i.e., -1) if the length
of this set is non-zero. Otherwise entry creation will 
fail.
