We had a number of comments and one DISCUSS from the other IESG members that were all solved before and during the meeting due to the excellent on-line cooperation with Juergen and with the editors. See the RFC Editor notes that reflect these discussions and the solutions proposed to solve the concerns from the other ADs. The document was not approved however because IANA asked for one more day to look at the IANA considerations and understand the actions that are required from IANA. I am holding a last DISCUSS until they come back to us and let us know if there are any more issues to solve or the document can be approved as is. I hope that no last minute hurdles will pop up.

The only difference is the match filter, where the configuration model uses other parameter names (ieId instead of fieldId) and allows ieName and enterpriseNumber as well. Of course, ieName does not make sense the MIB. enterpriseNumber could be added to the MIB as well. So, I suggest that you discuss an update of PSAMP MIB. After that, the changes can be adopted to the configuration draft accordingly.
