A bit string that identifies the ports that frames
destined to this address are forwarded to when received
on this port.
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
EtherSwitch 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'.
