A string of octets containing one bit per Vlan-Id for
VLANS with vlan index values of 0 through 4096.
The first octet corresponds to VLANs with
vlan index values of 0 through 7, the second
octet to VLANs 8 through 15, etc. The most
significant bit of each octet corresponds to the
lowest vlan index value in that octet.
For each VLAN that this policy should apply to
as a VLAN ACL, the corresponding bit is set to '1'.
