The set of ports to which frames received from a
specific port and containing the specific packet
string of the corresponding filter number are allowed
to 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 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'. (Note that the
setting of the bit corresponding to the port from which
a frame is received is irrelevant.)
