  2. RMONMIB WG Agenda -- I-Ds • (A) draft-ietf-rmonmib-framework-02.txt • (B) draft-siddiqui-rmonmib-raqmon-framework-00.txt • (C) draft-siddiqui-rmonmib-raqmon-pdu-00.txt • (D) draft-siddiqui-rmonmib-raqmon-mib-00.txt • (E) draft-bakke-dhc-snmp-trap-01.txt

  3. RMONMIB WG Agenda -- IETF 55 (1/2) 1) Implementation Reports (20 min) • Discussion of the implementation reports for: • SMON MIB (RFC 2613) Advancement • RMON2-MIB (RFC 2021) Advancement • RMON-PI (RFC 2074) Advancement • Goals: • Determine if RFC 2021 should be advanced by deprecating unimplemented objects or not advanced at this time. 2) RMON Framework Document (30 min) • Discussion of the RMON Framework document (A) • Determine if the framework is complete and ready for WG Last Call

  4. RMONMIB WG Agenda -- IETF 55 (2/2) 3) Real-time Application Quality of Service Monitoring (70 min) • Discussion of the RAQMON Framework (B) • Determine if the framework is complete • Should the framework provide extensibility and allow for future PDU types and/or delivery mechanisms • Discussion of the RAQMON PDU (C) • Determine if the PDU contains all appropriate fields • Should there be different high-level conformance levels to allow devices to subset the PDU fields in a consistent manner? • Should devices which use the SNMP Notification transport be required to support any command responder features? • Can the 'DHCP Option for SNMP' (E) mechanism be used to fully configure RAQMON devices which use the SNMP based PDU? • Discussion of the RAQMON MIB (D) • Determine (if possible) if the MIB is complete for: • configuration • reported attributes collected from RAQMON PDU

  5. RFC 2613 Implementation Report • Only 4 reports received; 2 from the same vendor • Includes 2 manager and 4 agent reports • Agents: 2 probe and 2 embedded switch implementations • At least 2 other implementations; did not respond in time • There are at least 2 independent implementations of every object in the MIB • Not every SmonDataSource value represented • All 4 did IfIndex.<I>; 1 did Vlan.<V> and 1 did EntPhysicalIndex.<N> • Not every Port Copy mode supported • 2 did 1:1; 1 did N:1; 1 did N:M • Recommend that RFC 2613 be advanced to Draft Standard

  6. RFC 2074 Implementation Report • Only 2 RMON-PI reports received • Includes 2 agent reports • Both agents are probe implementations • At least 2 other implementations; did not respond in time • There are at least 2 independent implementations of every feature of the Protocol Identifier macro • ProtocolDirTable mibwalks indicates consistent protocol representations • Only 1 RMON-PI report indicates support for ‘countsFragments’ and ‘trackSessions’ parameters, but RMON-2 reports indicate more support • Recommend RFC 2074 be advanced to Draft Standard

  7. RFC 2021 Implementation Report (1/5) • Only 3 RMON-2 reports received • Includes 3 agent reports • 2 agents are probe implementations, 1 is SW-only • At least 2 other implementations; did not respond in time • All 3 agents implement every statistics table • Some objects implemented by only 1 agent • Some objects not implemented by any agent

  8. RFC 2021 Implementation Report (2/5) • Following objects have 1 implementation: • probeHardwareRev • probeResetControl • probeDownloadFile • probeDownloadTFTPServer • probeDownloadAction • probeDownloadStatus • netDefaultGateway • tokenRingMLStatsDroppedFrames • tokenRingMLStatsCreateTime • tokenRingPStatsDroppedFrames • tokenRingPStatsCreateTime • ringStationControlDroppedFrames • ringStationControlCreateTime • sourceRoutingStatsDroppedFrames • sourceRoutingStatsCreateTime

  9. RFC 2021 Implementation Report (3/5) • Following objects have no implementations: • serialConfigTable • serialMode • serialProtocol • serialTimeout • serialModemInitString • serialModemHangUpString • serialModemConnectResp • serialModemNoConnectResp • serialDialoutTimeout • serialStatus • serialConnectionTable • serialConnectDestIpAddress • serialConnectType • serialConnectDialString • serialConnectSwitchConnectSeq • serialConnectSwitchDisconnectSeq • serialConnectSwitchResetSeq • serialConnectOwner • serialConnectStatus

  10. RFC 2021 Implementation Report (4/5) • Following objects have no implementations: • netConfigTable • netConfigIPAddress • netConfigSubnetMask • netConfigStatus • TimeFilter implementations vary • Mibwalk/GetBulk/GetNext friendly • wrap to next object when TF index changes • Strict compliance • iterate through every TF value; mibwalk/getbulk may never end • Both modes supported • Proprietary MIB object to select mode

  11. RFC 2021 Implementation Report (5/5) • Decision needed on RFC 2021 Advancement • Wait for more implementation reports • Deprecate objects without 2 implementations and advance rest of MIB to Draft Standard • ‘Fix’ TimeFilter somehow and cycle at Proposed Standard • Add standard TF mode select object • Change TF behavior somehow to allow mibwalk/getbulk friendly behavior
