Indicates the administrative status of which
ports are monitored. All the monitored ports have
to be non-trunking port and belong to the same
Virtual LAN. The octet string contains one bit
per port. Each bit within the octet string
represents one port of the device. The ordering
of ports represented within the octet string is
in the same order as in the RFC 1493
dot1dStpPortTable.
The bit value interpretation is as follows:
1 = being monitored
0 = not being monitored
