The set of the switch's member ports for the VLAN. A port may reside within multiple VLANs only if the object vlanAllowMembershipOverlap has been set to enabled. This object cannot be used to configure VLAN membership. The table vlanMemberTable is used for that purpose. Each octet within the value of this object specifies a set of eight ports, with the first octet specifying ports 1 through 8, the second octet specifying ports 9 through 16, etc. Within each octet, the most significant bit represents the lowest numbered port, and the least significant bit represents the highest numbered port. Thus, each port of the VLAN is represented by a single bit within the value of this object. If that bit has a value of '1' then that port is included in the set of ports; the port is not included if its bit has a value of '0'. Initially, a single VLAN with all ports as its members is defined. This object is not supported by switches operating with firmware version greater than or equal to 6.00
