A string of octets containing one bit per VLAN for VLANS with vlanIndex values of 1024 through 2047. The first octet corresponds to VLANs with vlanIndex values of 1024 through 1031; the second octet to VLANs 1032 through 1039; etc. The most significant bit of each octet corresponds to the lowest value vlanIndex in that octet. For each VLAN, if it is mapped to this MSTP instance, then the bit corresponding to that VLAN is set to '1'. To create a row, write any of mstInstanceEditVlansMap, mstInstanceEditVlansMap2k, mstInstanceEditVlansMap3k or mstInstanceEditVlansMap4k, to a non-empty list. To destroy a row, write all of these four variables to an empty list.
