Each octet within this value specifies a set of eight
VLANs, with the first octet specifying VLANs 2049 through
2056, the second octet specifying VLANs 2057 through 2064,
etc. Within each octet, the most significant bit represents
the highest numbered VLAN, and the least significant bit
represents the lowest numbered VLAN. Thus, each sub
VLAN of the super VLAN is represented by a single bit
within the value of this object. If that bit has a value of
'1' then that VLAN is a sub VLAN of the super VLAN; the
VLAN is not a sub VLAN of the super VLAN if its bit has
a value of '0'.
