Description: The set of ports defined to be on other VLAN's to which tagged packets destined for this specific VLAN should also be sent. Thus, this variable defines ports on the system that reach stations downstream which are on this VLAN and to which traffic may be forwarded. 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 system 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 VLAN; the port is not included if its bit has a value of '0'.
