Open discussion Agenda Item 1: Administrivia, current documents status Andy presented the agenda. There were no request for changes or additional agenda items. David Perkins was introduced as the new WG advisor. Andy presented on overview of the status of work in the frnetmib group. The following drafts are in progress: draft-ietf-frnetmib-frs-mib-08.txt - In IETF last call. Will complete last call on the 16 Nov. The next version of RFC1604, this MIB will also be a proposed standard. draft-ietf-frnetmib-atmiwf-03.txt - The MIB for FRF.8 is in progress. Working Group Last Call produced a substantive comment from Keith McCloghrie. Keith identified a problem with the proposed AToMMIB hook used to identify an interworked connection. The proposal was to overload the ATM textual convention AtmConnKind with enumerations indicating the type of cross-connect, not just the type of connection. This goes beyond the DESCRIPTION of AtmConnKind. Keith recommended adding a new object to the FR/ATM IWF MIB that will augment the atmVclTable with the index of the applicable FR/ATM IWF MIB cross-connect row. This change will be made in a new version of draft-ietf-frnetmib-atmiwf that will be forwarded to the IESG for review. Agenda Item 2: Rob Steinberger and Orly Nicklass, draft-steinberger-frmrelay-service-01.txt, Definitions of Managed Objects for Frame Relay Service Level Definitions Rob presented the current version of the FR Service Level Definition MIB. The MIB provides a mechanism to control and report results from a data store based on FRF.13. This Frame Relay Forum document provides a number of metric definitions for frame relay service level reporting. Issues from Oslo Meeting The relationship between this MIB and the SLAPM MIB was raised as an issue in Oslo. Rob advised that the SLAPM MIB applies to L3 or higher flows. It does not account for all the definitions in FRF.13 and has no parent group. As such, no attempt will be made to reconcile the two approaches to SLA MIB support. However, the SLAPM MIB contained better support for data persistence using purge control variables and this has been adopted in the FRF.13 MIB. Delay values should be measured in microseconds to accommodate faster speeds. (done) Variety of typos fixed TimeTicks replaced w/TimeStamp Relationships with other MIBs provided. Section added on MIB structure. A request was made for a capability object bit string to identify what the agent will support. Rob will add this object. Rob asked for guidance on the sample control table index (SmplIdx). This will be retained to support multiple manager access to the samples. Rob pointed out an error in the document on frsldPvcDataDelayMin/Max/Avg. The reference is to the free-running table and this should have relevance only to the free running world. This will be corrected. Current open issues: Rename as working group document Detach delay data from the sample table Need IANA experimental ID Need capability object to identify which objects are read/write RAD reported they had an early working implementation of the MIB. A new revision will be forthcoming. Agenda Item 3: Prayson Pate, Bob Lynch, and Ken Rehbehn, draft-pate-mfrmib-00.txt, Definitions of Managed Objects for Monitoring and Controlling the UNI/NNI Multilink Frame Relay Function Prayson presented a proposed MIB for the UNI/NNI multilink FR documented in FRF.16. A tutorial of the FRF.16 functionality was provided to the Working Group. The bundleIndex will be changed to Integer32. The bundle table index will be changed to ifIndex. An IANA request will be made for the ifType and MIB tree. A NMS vendor requested that the number of active bundle links be explicitly reported. The original design required NMS to scan the table to avoid creating objects that duplicate information that can be derived from other MIB objects. Unfortunately, the industry has many inconsistent implementations of agent support and some of the dependent objects may not report link state correctly. The group agreed to add objects to report number of links configured and number of links that are active. Prayson reported that the MIB was compiled by SMICng. David Perkins recommended use of a newer version of the compiler. This draft was accepted as a working group document with the changes agreed to in this meeting. A new revision will be forthcoming. Agenda Item 4: Open discussion Several MIBs have been on the list of active working group items with no progress or apparent interest. The authors are no longer working on the documents and, unless new editors volunteer to work with the MIBs, the work will be terminated. These drafts are: draft-ietf-frnetmib-spvc-02.txt, Frame Relay Switched PVC MIB, Bill Coutts draft-ietf-frnetmib-dte-svc-00.txt, Don Cochrane draft-ietf-frnetmib-dcp-02.txt, Moji Kashef, Jaime Colom No additional items were brought up, and the group adjourned.
