| Description | A string of octets containing one bit per VLAN for
VLANS with VlanIndex values of 2048 through 4095. The
first octet corresponds to VLANs with VlanIndex values
of 2048 through 2055; the second octet to VLANs 2056 through
2063; 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 MST instance,
then the bit corresponding to that VLAN is set to
'1'. Each VLAN can only be mapped to one unique MST
instance with the range from 0 to stpxSMSTMaxInstanceNumber.
If the bit corresponding to a VLAN is changed from '1'
to '0', then that VLAN will be automatically mapped to
SMST instance 0 by the device. If the bit corresponding
to a VLAN is changed from '0' to '1', then that VLAN will
be automatically removed from the MST instance this VLAN was
previously mapped to. If the length of this string is
less than 256 octets, any 'missing' octets are assumed to
contain the value of zero. |
