stpx Preferred MST Instances Map

1.3.6.1.4.1.9.9.82.1.11.10.1.1

A string of octets containing one bit per MST instances on this trunk port. The first octet corresponds to MST instances of 0 through 7; the second octet to MST instances 8 through 15; etc. The most significant bit of each octet corresponds to the lowest MST instance value in that octet. The number of bits for this mib object will be determined by the value of stpxMSTMaxInstanceNumber. For each instance, if it is preferred on this trunk port, then the bit corresponding to that instance is set to '1'.
