That can be accomplished through standardized attributes or vendor-specific attributes that are sufficiently well documented (and not subject to patents) that third parties can implement collectors or analysis tools that interoperate with the vendor tools for the vendor attributes. Will we be able to meet these interoperability goals? Why or why not? _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
