Well, I jumped up and answered wrongly then. ;-)

Isn't port priority the last thing the Spanning Tree Algorithm looks at?
AFAIK the selection of root port should be, in order: Root Bridge ID,
Port Path Cost, Sending Bridge ID and at last Sending Port ID, which is
Port Priority and Port Index.

Are the three ports all pointing towards the root bridge?
