A string of octets containing one bit per VLAN in the management domain on this trunk port. The first octet corresponds to VLANs with VlanIndex 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 value VlanIndex in that octet. If the bit corresponding to a VLAN is set to '1', then this VLAN is presently being forwarded on this trunk port, i.e., it is not pruned; if the bit is set to '0', then this VLAN is presently not being forwarded on this trunk port, either because it is pruned or for some other reason.
