I think Michael wanted to post notification definitions that help reduce the number of notifications emitted if for example all virtual machines of a hypervisor change state at about the same time (e.g., because the physical server is restarted). This may be a good thing since it reduces the number of notifications at the source and as such works independently of RFCs 3014 or 3877. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1, 28759 Bremen, Germany Fax: +49 421 200 3103 <http://www.jacobs-university.de/> _______________________________________________ OPSAWG mailing list [email protected] https://www.ietf.org/mailman/listinfo/opsawg
