IPCDN Working Group

RFIv2 MIB Draft Changes

• Draft 06 discussed in IETF 56

• Draft 07 – Final Revision by Primary Author David Raftus (Terayon)– Many thanks to David for leading the RFI v2 MIB development since

the initial DOCSIS 2.0 inception.– David closed a considerable number of items in draft 07

(see details next slides)

• Draft 08 – Eduardo Cardona (CableLabs) closed remaining open issues via the

IPCDN mailing list and published draft 08– List of remaining open issues that are in scope sent on 10/1/2003

IPCDN Working Group

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


• Enhanced descriptions in docsIfUpstreamChannelTable for the interface clone mechanism (continued in draft 08).

• Added objects for CM compliance to count UCC transactions: docsIfCmStatusUCCs and docsIfCmStatusUCCFails in docsIfCmStatusTable.

• Object docsIfCmtsCmStatusTimingOffset units set back as per RFC 2670 and add extra granularity with new object docsIfCmtsCmStatusHighResolutionTimingOffset.

• Added object docsIfCmtsCmStatusValueLastUpdate in docsIdCmtsCmStatusTable

IPCDN Working Group


• Added Normative References including associated to IMPORT clauses

• Resolved known Draft 07 issues:– Old Section 11 “Conflict Resolution with docsIfExt MIB” was removed

the 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


• Interface Cloning Process:– Added DEFVAL for docsIfUpChannelPreEqEnable

mainly for temporary created rows– Change MAX-CLAUSE of docsIfUpChannelType to read-

only; Removed OBJECT clause in docsIfBasicComplianceV2

– Clarifications and enhanced DESCRIPTION clauses for objects docsIfCmtsModulationEntry, docsIfUpChannelModulationProfile, docsIfUpChannelType, docsIfUpChannelStatus, docsIfUpChannelCloneFrom and docsIfCmtsModChannelType

– Closed: Not added global byte counters in docsIfCmtsCmStatusTable

IPCDN Working Group

RFI v2 MIB - pending final Draft 09

• Draft Status– 3 final items to be addressed in draft 09– Need an update to the security consideration section

• Comments in ifAdminStatus from Jason Tessier– Section 3.2.5.2. ifEntry for Upstream interfaces, remove IfAdminStatus

SNMP set “chain” effect.

• Editorial and Technical comments on Interface cloning process– Object docsIfUpChannelUpdate:

Remove SCDMA specifics, in other objects of docsIfUpstreamChannelTable already done -draft-08-.

– Correct the syntax of SNMP error codes GEN_ERROR and COMMIT_FAILED_ERROR for genError and commitFailed respectively.

• Update Security Section– Update information to reflect current MIB Security consideration

structure– Remove references to RFC 3414 and RFC 3415

Eduardo Cardona, [email protected]

November 2003

IPCDN Working Group

BPI+ MIB Draft 12 Changes

• 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

BPI+ MIB draft 12 Changes (continued)

docsBpi2ObsoleteObjectsGroup and its objects entirely from I-D

IPCDN Working Group

DOCSIS QoS MIB

draft-ietf-ipcdn-qos-mib-09

Michael Patrick & William MurwinMotorola BCS

November 2003

IPCDN Working Group

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

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

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

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

Draft History (4)

• DOCS-IETF-QOS-MIB version 9 (cont)– Removed Bullet from Section 2.2.2.1

This 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.
