Even an implementation that claims > compliance to bridgeCompliance1493 will be impacted because the > semantics of objects from RFC 1493 have been changed. dot1dStpPriority: dot1dStpPortPriority: I think the change is really a clarification that only a subset of the original value range is allowed for bridges that comply to IEEE 802.1t or IEEE 802.1w so I do not see a real problem here for _agent_ implementations. Bridges supporting IEEE 802.1t or IEEE 802.1w likely reject values which are outside the set of legal values and I would guess that this is exactly what is currently implemented and deployed. Can someone confirm my guess? dot1dStpTimeSinceTopologyChange: Can't really judge the difference since I do not know enough about RSTP and tcWhile timers. Can someone explain what the impact of this change might be? dot1dStaticAllowedToGoTo: I am not sure what the issue here is. Did this semantically chance at all? /js -- Juergen Schoenwaelder International University Bremen <http://www.eecs.iu-bremen.de/> P.O.
