OctetString
An indication of which ports are forwarding by spanning
tree for the specified VLAN. The octet string contains
one bit per port on the bridge for the specified VLAN.
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.
The bit value interpretation is related to RFC 1493
dot1dStpPortState values is as follows:
1 = forwarding
0 = disabled, blocking, listening, learning, broken, or
nonexistent
