  10. RFI v2 MIB Draft 07 Changes (1) • Corrected MIB Module name to DOCS-IF-MIB • Draft 06 had DOCS-IETF-IF-MIB • RFI v2 replaces RFC 2670 • Updated DESCRIPTION clause in several objects: • Clarifications in docsIfCmtsChannelUtUtilization, docsIfUpChannelPreEqEnable, docsIfCmStatusEqualizationData, docsIfSignalQualityEntry and docsIfCmtsChannelUtilizationInterval • Discontinuity notes added for counters in docsIfCmtsDownChannelCounterTable and docsIfCmtsUpChannelCounterTable • Adjusted “Grants” types in docsIfCmtsInsertInterval • Added Enumeration values: • unknown(0) to docsIfCmtsModPreambleType • registeredBPIInitializing(9) to docsIfCmtsCmStatusValue IPCDN Working Group

  12. RFI v2 MIB Draft 08 Changes (1) • Added Normative References including associated to IMPORT clauses • Resolved known Draft 07 issues: • Old Section 11 “Conflict Resolution with docsIfExt MIB” was removedthe private docsIfExt MIB module is not and should not be an IPCDN submission • New section 11 “Management Interoperability of DOCSIS 1.0, 1.1 and 2.0” added as well as glossary terms DOCSIS 1.0/1.1/2.0. to handle more intuitively 'DOCSIS 1.x' extensive term usage. • Added docsIfCmtsOptionalv2 GROUP for optional objects from table docsIfCmtsDownChannelCounterTable. • Removed from DESCRIPTION clauses “optional” requirements. IPCDN Working Group

  15. IPCDN DOCSIS Cable Device v2 MIBdraft-ietf-ipcdn-device-mibv2-06 Rich Woundy, Editor Richard_Woundy@cable.comcast.com November 2003 IPCDN Working Group

  16. Modifications since –05 • Added DiffServ MIB compliance statements for IP filtering • Especially Data Path, Classifier, and Action tables • Deleted docsDevFilterInetTable • DiffServ MIB is used instead of defining new tables • Deprecated IPv4-only, IP ToS filtering objects • docsDevFilterIpTable, docsDevFilterPolicyTable, docsDevFilterTosTable, docsDevCpeTable • Editorial changes • Updated some references; added DOCSIS 2.0 references • Further IPv4 compliance text added IPCDN Working Group

  18. IPCDN DOCSIS Subscriber Management MIBdraft-ietf-ipcdn-subscriber-mib-13.txt Wilson Sawyer wsawyer@ieee.org November 2003 IPCDN Working Group

  19. Mostly editorial changes since –12 • Numerous clarifications and textual discrepancies fixed in response to MIB doctor comments from Bert Wijnen and Harrie Hazewinkel. • Filter group indices changed to 1..255 or 0..255 to better reflect DOCSIS signaling. • No other functional changes. • Further IPv4/v6 compliance text added. IPCDN Working Group

  20. Subscriber Mgmt MIB I-D Status • Status reported by Wilson: • Draft 13 completes WG last-call • Draft 13 draft remains mib-unrooted; not implementable until published as RFC. • WG Status • Draft 13 ready for publication • Request to AD after IETF#58 meeting IPCDN Working Group

  21. IPCDN DOCSIS BPI Plus MIBdraft-ietf-ipcdn-bpiplus-mib-12 Eduardo Cardona, Editor e.cardona@cablelabs.com November 2003 IPCDN Working Group

  22. BPI+ MIB Draft 12 Changes • Draft 10 discussed in IETF 57 • Draft 11 • No technical change, simply updates Authors’ Contact information • AD review received on Draft 11 on 10/14/2003 • Draft 12 • AD review comments addressed including administrative, editorial & technical • Added section 2.2 to explain the relationship between the informative reference of BPI MIB Module (RFC 3083) and BPI+ Mib Module. • Further IPv4/v6 compliance text added • TEXTUAL-CONVENTION DocsBpkmSAType description aligned with enumeration labels. • 2 new TCs added for Security Association IDs: DocsSAId and DocsSAIdOrZero • DocsSAId, used for Indexes in docsBpi2CmTEKSAId, docsBpi2CmtsTEKSAId, and docsBpi2CmtsMulticastAuthSAId. • DocsSAIdOrZero used for for Columnar objects; zero value means SAID not yet determined. IPCDN Working Group

  23. BPI+ MIB draft 12 Changes (continued) • Draft 12 • Removed Obsoleted group docsBpi2ObsoleteObjectsGroup and its objects entirely from I-D • docsBpi2CmtsAuthCmGraceTime • docsBpi2CmtsTEKGraceTime • Renumbered OIDs for the following tables: • docsBpi2CmtsAuthTable • docsBpi2CmtsTEKTable • WG Status • Draft 12 ready for publication (minor date error that will be fixed anyway in RFC edits) • Request publication to AD after IETF#58 IPCDN Working Group

  24. DOCSIS QoS MIB draft-ietf-ipcdn-qos-mib-09 Michael Patrick & William Murwin Motorola BCS November 2003 IPCDN Working Group

  25. Status of QoS MIB • Draft version 9 addresses all issues from IPCDN and DOCSIS OSS working groups to date. • Ready for WG-Last Call and then submission to IESG • Open IssueWG Chairs to seek AD advice on the use of IP ToS instead of IP DSCP IPCDN Working Group

  26. Draft History (1) • DOCS-QOS-MIB version 4 • tComLabs & Cable Labs require DOCS-QOS-MIB version 4 for Certification Wave Testing. • All DOCSIS 1.1 & 2.0 certified CMs and CMTSs currently implement DOCS-QOS-MIB version 4. • DOCS-QOS-MIB version 5 • The description of docsQosServiceFlowPkts was changed to avoid requiring CMs to classify downstream packets. However the new description gave the impression that this counter now counted delayed, dropped, and transmitted packets. • DOCS-QOS-MIB version 6 • InetAddress objects added in favor of IpAddress syntax for IPv6. • Deprecated objects of type IpAddress for backwards compatibility with DOC-QOS-MIB version 4. • Added objects that were removed from earlier revisions of the MIB, as obsolete objects. This was done to explain the gaps in the numbering of objects, to prevent re-use in future versions of the MIB. IPCDN Working Group

  27. Draft History (2) • DOCS-QOS-MIB version 7 • Re-rooted the MIB • Added 64-bit packet counters • ECN RFI-N-02091 changed the default values for the Maximum Traffic Burst and the Maximum Concatenated Burst • Clarify the packet counters descriptions • DOCS-IETF-QOS-MIB version 8 • Addressed all Issues from IPCDN Interim Meeting Denver, CO (Feb 13, 2003) • MIB Module name was changed to correspond to Re-Rooting the of the MIB in version 7 • Add StorageType objects to tables with RowStatus objects • Use of InetPortNumber • Text revised to mention DOCSIS 2.0 as well as 1.1 IPCDN Working Group

  28. Draft History (3) • DOCS-IETF-QOS-MIB version 9 • All DisplayString objects changed to SnmpAdminString Syntax. • This change is a preventive measure in case DOCSIS ever changes the Cable Modem Configuration File to support UTF-8 characters, which currently is ASCII only for Service Class Names. • Impact:Since SnmpAdminString values are encoded the same for ASCII characters as DisplayString values, this has minimal impact on agents that support the DOCSIS QOS MIB using DisplayString. • Potential Impact: If DOCSIS was ever changed to use UTF-8 for Service Class Names and the MIB still displayed Service Class Names as DisplayStrings, then a new version of the DOCSIS-IEFT-QOS-MIB would be required that deprecated an number of service class name objects, as well as deprecated the docsQosServiceClassTable because the docsQosServiceClassName(DisplayString) is the index to this table. docsQosServiceClassName is the only Read-Create Service Class Name, and its description contains the current DOCSIS rules for this object as well as a reference to the DOCSIS Specification where the rules are stated. IPCDN Working Group

  29. Draft History (4) • DOCS-IETF-QOS-MIB version 9 (cont) • Removed Bullet from Section 2.2.2.1This bullet discussed how the docsIfCmtsServiceInOctets and docsIfCmtsServiceInPackets should operate. This should now be handle by the DOCSIS RF-MIBv2 and not by the DOCSIS QOS MIB. • Updated the Packet Counter Description • The descriptions to docsQosServiceFlowPkts, docsQosServiceFlowPHSUnkowns, docsQosServiceFlowPolicedDropPkts, and docsQosServiceFlowPolicedDelayPkts have been updated and agreed upon by all parties involved. Everyone seems content with the current descriptions. • docsQosPktClassVlanId syntax changed • The docsQosPktClassVlanId syntax has been changed to Integer32 (0|1..4094) which is inline with the textual convention, “VlanIdOrNone”, being proposed draft ietf-ops-vlanid-tc-mib-00.txt. VLAN 4095 is reserved in IEEE 802.1Q and will be used in IETF to mean “Any” VLAN, a concept that DOCSIS does not have. • IP ToS vs. Differentiated Services • The DOCS-IETF-QOS-MIB has always and continues to use IP Type of Service instead IP DSCP, because of the DOCSIS Protocol use of IP ToS. • There is concern that the DOCS-IETF-QOS-MIB uses IP ToS. • Thus Section 4, DOCSIS and IPv4 Type-of-Service(ToS) Field, was added to explain that the DOCS-IEFT-QOS-MIB just reflects the DOCSIS protocols use of IP ToS Fields.
