connPvcHighIfIndex

The line interface number (ifIndex) of the high port.
Normally, the high port has a higher ifIndex value than
the low port.  However, for point-to-multipoint
connections, the root is always the low port, regardless
of whether it is greater or smaller than the port numbers
of individual leaves.  Line interface number 17 
corresponds to gateway (the switch's internal port).
