Les,
We would like to define "auto selection" for PortPathCost.
I mean, for example, if dot1dStpAdminPortPathCost32 is set to "0",
the agent could select dot1dStpOperPortPathCost32 automatically,
corresponding to table 17-7 in 17.28.2 of 802.1s.
When dot1dStpAdminPortPathCost32 is set to positive value, agent could
use this value for dot1dStpOperPortPathCost32.
I don't see any other solution to force the agent to use table 17.7.
May be I missed something?

Thank you for your interest in my remarks, Alex
