Description: The set of ports which are permanently configured to transmitting traffic for this VLAN as either tagged or untagged frames.

Each octet within this value 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 bridge 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'.

Changes to this object affect the per-port per-VLAN Registrar control for Registration Fixed for the relevant GVRP state machine on each port.

A port may not be added in this set if it is already a member of the set of ports in dot1qVlanForbiddenEgressPorts.

The default value of this object is a string of zeros, indicating not fixed.
