Description: If the switch is operating in 802.1Q mode, this selects whether GVRP protocol messages should be processed and VLANs configured accordingly for each port on the switch. Each octet within the value of this object specifies a set of eight ports, with the first octet specifying ports 1 through 8, the next octet specifying ports 9 through 16, etc. Within each octet, the least significant bit represents the lowest numbered port, and the most significant bit represents the highest numbered port. Thus, each port of the VLAN bridge is represented by 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'
