Maintenance Task Group

Between this session and the preceding session, the Maintenance TG held the following electronic meetings:

Call to order July 14, 2020 at 2:00 PM EDT by Paul Congdon, IEEE 802.1 Maintenance TG Chair, who presided and wrote the minutes.

The table in section 1 reflects the attendance and affiliation of participants who registered their attendance in IMAT.

Agenda items and dispositions:

1. Meeting introduction. The TG Chair reminded participants that the following information was made available before the meeting:

The IEEE SA Copyright Policy slides,

The IEEE SA PatCom Patent Slides for Standards Development Meetings,

The IEEE SA slides regarding IEEE Codes of Ethics and Conduct, participation in the “individual process”, and dominance,

The decorum information, and

The reminder for participants to register their attendance in IMAT

contained in “MEETING INTRODUCTION” http://www.ieee802.org/1/files/public/templates/admin-WG+TG-intro-0720-v01.pdf thereby providing the information on slides 2 and 5 of this presentation and made the Call for Potentially Essential Patents and there were no responses to this Call prior to the end of the session.

2. Approval of agenda. The TG Chair presented the agenda in https://1.ieee802.org/maintenance-tg-conference-call-agenda-july-14th-2020/.

Disposition: the agenda was reviewed, discussed, and agreed (informally, none dissenting) as presented.

3. P802.1Q-Rev status update.  John Messenger presented http://www.ieee802.org/1/files/private/q-rev-drafts/d0/802-1Q-rev-d0-2.pdf.

Disposition: A motion will be entertained at the closing plenary meeting to commence WG ballots on the P802.1Q-Rev draft.  The goal is to submit to RevCom by March 2021 to not block future 802.1Q amendments. This schedule would imply an SA ballot motion needs to pass in November 2020. Possible additional amendments that could be included in P802.1Q-Rev are P802.1Qcx and P802.1Qcr. The WG chair indicated he will request that IEEE staff begin pre-publication edits on P802.1Qcx and P802.1Qcr as soon as possible so they could be easily included in the revision. A project page is being set up to house future drafts and project status.

4. SC6 Status. Karen Randall presented the SC6 Status in http://www.ieee802.org/1/files/public/docs2020/maint-congdon-concall-bis-0720-v01.pdf.

Disposition: Agreed (informally, none dissenting) to always send amendments for information, but we may want to evaluate if we will send for adoption when a subsequent base standard revision is imminent.  Action item on Karen and the TG Chair to email Jodi Haasz informing her of our preference to not send P802.1Qcx for adoption because it will roll into P802.1Q-Rev soon.  The motion for P802.1Qcx should be pulled from the Maintenance TG motions for the closing plenary.

5. SC6 Liaisons.  Karen Randall presented the proposed response to FDIS ballot comments on:

802.1Xck-2018 http://www.ieee802.org/1/files/public/docs2020/maint-randall-SC6CommentResponse1XckFDIS-0720-v01.pdf

802.1AE-2018 http://www.ieee802.org/1/files/public/docs2020/maint-randall-SC6CommentResponse1AERevFDIS-0720-v02.pdf

Disposition: No changes to the responses were recommended.  A motion to submit the responses will be made in the closing plenary.

6. Document vehicle status.  The TG Chair presented the status of current documents in progress used as vehicles for resolving maintenance items shown in http://www.ieee802.org/1/files/public/docs2020/maint-congdon-concall-bis-0720-v01.pdf.

7. New Maintenance Items. The TG Chair led the discussion on new maintenance items:

0271 – Default configuration for bridges that support credit-based shaper https://www.802-1.org/items/386

Disposition: Details for discussion on all items are logged in the IEEE 802.1 maintenance database at https://www.802-1.org/home where items progressed at the meeting can be reviewed by selecting ‘Meetings’.

8. Any Other Business. No other business was discussed by the Maintenance TG in this session.

9. Future meetings. Agreed (informally, none dissenting) to hold future conference calls to be announced on the 802.1 email exploder with specific dates/times subject to notice of at least 10 days.  Next meeting needs to occur prior to the completion of the P802.1Q-Rev WG ballot in order to submit maintenance items as comments.

The Maintenance TG meets next during the September 2020 IEEE 802.1 session.

4:33 PM adjournment

Call to order Jul 13, 2020 at 1:30 PM EDT by Mick Seaman, IEEE 802.1 Security TG Chair, who presided and wrote the minutes.

Agenda items and dispositions:

1. Meeting introduction. The TG Chair reminded participants that the following information was made available before the meeting and showed:

The IEEE SA Copyright Policy slides,

The IEEE SA PatCom Patent Slides for Standards Development Meetings,

The IEEE SA slides regarding IEEE Codes of Ethics and Conduct, participation in the “individual process”, and dominance,

The reminder for participants to register their attendance in IMAT

contained in “MEETING INTRODUCTION” http://www.ieee802.org/1/files/public/templates/admin-WG+TG-intro-0720-v01.pdf thereby providing the information on slides 2 and 5 of this presentation, and made the Call for Potentially Essential Patents at the beginning of this meeting and at the beginning of the TG meetings on Jul 14, 2020 and Jul 15, 2020 in this session. There were no responses to these Calls prior to the end of the session.

2. Approval of agenda. The TG Chair presented the agenda in https://1.ieee802.org/security-tg-electronic-meetings-july-13-15-2020/

Disposition: the agenda was reviewed, discussed and agreed (informally, none dissenting) as presented.

3. P802.1AEdk MAC Privacy protection – Draft development

3.1. Don Fedyk, P802.1AEdk Editor, presented the updated draft P802.1AEdk/D0.2 http://www.ieee802.org/1/files/private/dk-drafts/d0/802-1AEdk-d0-2.pdf

Clause 19, Encoding of MAC Privacy-protection Protocol Data Units, remained essentially complete and had not been changed. Some reconciliation of statistics/counter names is required. The names given in angle brackets, e.g. <outMPPDUFrames> as initial placeholders have not been updated. Different tools have different preferred name styles, e.g. camel case as currently shown is used in MIBS and in the existing MACsec management description (10.7 of 802.1AE-2018) as opposed to all lower case with hyphen separators in YANG.

Clause 17, MAC Privacy protection (overview), was largely unchanged but with some tweaks to the mapping of PrY user priority to PrY access priority to accommodate PrY and SecY in separate systems. Noted that PrY user priority could be a useful indication of not applying privacy, allowing (for example) TSN traffic assigned to priorities 1 or 2 to be forwarded without encapsulation in MPPDUs, not requiring use of the stream_handle to provide further granular selection of non-privacy protected traffic.

Noted, in the context of Clause 17 but not yet mentioned the potential effect of maintaining bandwidth utilization for privacy when packet loss was causing TCP to backoff, leading to continual reduction of useful throughput and its replacement with padding. Agreed (informally, none dissenting) that users should be aware of the need to remain within the SLA to avoid this effect (needs mentioning in Clause 17). No desire to introduce additional congestion avoidance/reaction protocol.

3.2. Mick Seaman presented suggested text for Clause 21, MAC Privacy protection in Systems, as incorporated in the updated (D0.2) draft.

No attempt to cover all possible cases, but to provide an adequate description of cases which have led to questions in the past, e.g. position of link aggregation facilitates simple fragment reassembly where individual links are order preserving.

To improve privacy text allows multiple inner C-VIDs to map to a single outer C-VID, reducing visibility of inner C-VID use or improving utilization when defeating activity monitoring. Suggested to retrofit this flexibility to EDEs without privacy protection, relaxing existing constraint. Should also add to clause 17 text to introduce in overview.

Disposition: Discussion to be continued in this session.

3:30 PM EDT recess

Call to order Jul 14, 2020 at 11:04 AM EDT by Mick Seaman, IEEE 802.1 Security TG Chair, who presided and wrote the minutes.

4. P802E Recommended Practice Privacy Considerations for IEEE 802 Technologies – Submission to RevCom. The TG Chair led a brief review of the SA ballot status and the next steps. The second SA recirculation ballot closed without further comments or vote changes, with cumulative 95% Approval. The disposition of comments on the recirculation http://www.ieee802.org/1/files/private/802-e-drafts/d2/802E-d2-0-sponsor-r2-dis.pdf was thus purely administrative and had been prepared by the TG Chair. Agreed (informally, none dissenting) to propose a motion to forward to RevCom for final approval.

Disposition: Motion to forward to RevCom proposed and approved in the 802.1 WG closing plenary electronic meeting Jul 20, 2020, added to the LMSC EC consent agenda and subsequently approved by the EC. Anticipate approval recommendation (to the SASB) by RevCom in their Sep 20, 2020 meeting.

5. ISO/IEC JTC1 SC6 progression of IEEE 802.1 Standards. Karen Randall, Security TG Vice-Chair and 802.1 Liaison Secretary, presented proposed responses to comments received on the FDIS ballots of IEEE Std 802.1AE-2018 and IEEE Std 802.1Xck-2018. Minor editorial wording corrections were suggested.

Disposition: Text forwarded for consideration by the IEEE 802.1 Maintenance TG and subsequently by the IEEE 802 SC6 SC (Standing Committee). Responses approved without further change.

6. P802.1AEdk MAC Privacy protection – Draft development (continued)

6.1. Mick Seaman continued the presentation of suggested text for Clause 21, MAC Privacy protection in Systems, as incorporated in the updated (D0.2) draft.

Discussion:

21.8 discusses scenario with PrY (privacy-protection) and SecY (MACsec) in separate devices. Anticipated addition to existing EDE secure provider link. Adds a further C-Tag so does not interoperate directly with combined case, but that is not the deployment scenario/requirement. Devices should be adjacent to minimize need to address intervening devices that do not understand MPPDUs.

6.2. Don Fedyk, P802.1AEdk Editor, initiated a discussion on validating the YANG solution.

Discussion:

IETF has YANG models in separate documents, similarly IEEE 802 projects has models in separate standards. To check the utility of the models in the context of some projects they need to be used in combination.

No intent to specify test cases, but with 802.1AE MACsec and privacy protection need to clearly specify the combination and how it works. Compare with approach in 802.1Qcp Figure 48-2.

Need to have something intelligible at a level that fits on a page, so the reader can get the picture.

Simplified management, if desirable, could follow the approach currently taken in 802.1AE Clause 16 (using MIB Modules to manage EDEs).

Need to decide what subsets of possible two-component behaviors could be specified.

Disposition: Discussion to be continued in this session.

12:57 PM EDT recess

Call to order Jul 15, 2020 at 11:04 AM EDT by Mick Seaman, IEEE 802.1 Security TG Chair, who presided and wrote the minutes.

7. P802.1AEdk MAC Privacy protection – Draft development (continued)

7.1. Don Fedyk, P802.1AEdk Editor, presented Clause 20, MAC Privacy-protecting Entity (PrY) operation of the updated draft P802.1AEdk/D0.2

All transmit Controlled Port traffic needs to pass through the PrY (change to Figure 20-1, knock on changes to Figures 20-2,-3,-4) as it needs to be counted towards the SLA even if not privacy protected. There is no Controlled Port access separate from the Private Port.

Using just the Private Port, rather than Private Port + Controlled Port, simplifies the view of the service provided from the point of view of the operation of network configuration/routing protocols. These are assumed to use the Private/Controlled Port.

Uncontrolled Port use is assumed to be restricted to low bandwidth/low frequency protocols for (logical) nearest neighbor exchanges, e.g. 802.1X EAPOL and MKA, 802.1AB LLDP (when running prior to or underneath link security).

Privacy/MPPDU encapsulation selectable for Private Port transmit frames based on PrY user priority or (for finer granularity, conformance option, detailed management not to be specified) on stream_handle (ISS connection_identifier sub-parameter) as specified by 802.1CB and used by 802.1Q PSFP and ATS.

Bandwidth rate targets/parameters need to be in terms of what will be transmitted black-side, i.e. through the Provider Network Port, per PEP (equates to provider service instance, remote PEP in the common point-to-point case). This is to match the provider SLA and includes MPPDU overhead plus calculated allowance for MACsec and outer tag.

Need to warn against changes in channel rate targets as these can leak information. While regular changes, e.g. “office hours” may not such changes are unlikely to be advantageous as they are probably not reflected in the SLA.

Format checking in MPPDU frame, do not use “error” in cases where “unsupported in receiver’s version” could be a possibility.

7.2. Don Fedyk, P802.1AEdk Editor, led a discussion on the alignment of the SNMP MIB and YANG.

An Excel spreadsheet had been created to tabulate objects. To avoid the potential security risks of posted Excel spreadsheets this would be converted to CSV and uploaded for future discussion.

While both SNMP and YANG are derived from the main text as XML (802.1AE-2018 Figure 10-5 for the SecY/MACsec) they have different capabilities (e.g. in the organization of tables, and particularly of defaults) so a strict mapping would be suboptimal. No reason to suppose that the MIB has deployed ‘as is’, so this should not be a concern.

MIB has been created and is attached to D0.2.

YANG augmentation makes a significant difference vs separate MIBs for interface shim components. Remains unclear what the basic ietf-interface statistics refer to when frames are multiplexed and frame sizes are change in an interface stack – top of stack or bottom of stack.

7.3. Don Fedyk, P802.1AEdk Editor, presented “YANG based Config for MAC Privacy 802.1AEdk Third Attempt” http://www.ieee802.org/1/files/public/docs2020/dk-fedyk-dot1aedk-privacy-config-0720-v01.pdf

Disposition: Discussion to be continued in this session.

1:02 PM EDT recess

Call to order Jul 15, 2020 at 1:35 PM EDT by Mick Seaman, IEEE 802.1 Security TG Chair, who presided and wrote the minutes.

8. P802.1AEdk MAC Privacy protection – Draft development (continued). Don Fedyk, P802.1AEdk Editor, led a continuation of the discussion of YANG configuration of EDEs

Focus on the “simple” VLAN bridge case, and the extent it is possible to index by incoming (red-side) VLAN TAG.

Disposition: further discussion required. Input to editor requested. SNMP/YANG table uploaded at http://www.ieee802.org/1/files/public/docs2020/dk-fedyk-snmp-yang-xref-0720-v00.csv

9. Any Other Business. The TG Chair led a discussion of trademarking “MACsec”.

Disposition: Agreed (informally, none dissenting) to pursue trademarking possibility with IEEE staff.

10. Future meetings. The TG Chair led a discussion of future meetings.

Scheduling electronic meetings in a “virtual plenary” or “virtual interim” block, as for this session and the May interim session has worked well.

Other electronic meetings to be scheduled as input or an updated draft becomes available, subject to the usual notice.

Disposition: Motion for electronic meetings with the usual notice proposed and approved at the 802.1 closing plenary meeting.

2:57 PM EDT adjournment.

YANGsters

Between this session and the preceding session, YANGsters held the following electronic meetings:

Call to order Jul 16, 2020 at 2:05 PM EDT by Scott Mansfield, the YANGsters Chair, who presided and Stephan Kehrer, the YANGsters Secretary, wrote the minutes.

The table in section 1 of the session minutes reflects the attendance and affiliation of participants who registered their attendance in IMAT.

Agenda items and dispositions:

1. Meeting introduction. The YANGsters Chair reminded participants that the following information was made available before the meeting

The IEEE SA Copyright Policy slides,

The Guidelines for IEEE SA Meetings slide,

The IEEE SA slides regarding IEEE Codes of Ethics and Conduct, participation in the “individual process”, and dominance,

The decorum information, and

The reminder for participants to register their attendance in IMAT

contained in “MEETING INTRODUCTION” http://www.ieee802.org/1/files/public/templates/admin-prePAR-intro-0720-v01.pdf thereby providing the information on slide 2 of this presentation.

The YANGsters Chair announced that the meeting is subject to the Copyright Policy, and Participants Policy as read and displayed at the opening plenary meeting.

The YANGsters Chair made the Call for Potentially Essential Patents: there were no responses to this Call prior to the end of the session.

2. Approval of agenda. The YANGsters Chair presented the agenda in https://1.ieee802.org/2020-07-w29-plenary-session-electronic-yangsters-agenda/.

Disposition: the agenda was reviewed, discussed and updated as recorded by these minutes.

3. Introduction to YANGsters. The YANGsters Chair presented “YANGster Meeting Week 29 2020” http://www.ieee802.org/1/files/public/docs2020/yangsters-smansfield-meeting-agenda-w29-0720-v03.pdf.

An introduction on YANGsters and what the group is doing was provided by the YANGsters Chair, as can be seen on slides 3-5 of that presentation.

Disposition: Presentation discussed.

4. Handling of Errata in YANG. The YANGsters Chair led the discussion.

How are errata or small changes handled in YANG correctly?

Errata to YANG files typically are not allowed.

Reason: revision dates in a YANG module should uniquely identify the content.

To update or correct a YANG module, a new YANG module with a new revision date needs to be created.

Currently, changes need to be backwards compatible (e.g. if a leaf has a wrong name the old node needs to be deprecated and a new node with the correct name needs to be added).

The IETF NetMod Working Group is currently working on “YANG Semantic Versioning” https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-semver/ and on “YANG Module Versioning Requirements” https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-versioning-reqs/. Comments on these two drafts are encouraged to netmod@ietf.org.

Also “YANG Versioning Solution Overview” https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-solutions/ covers the full set of five solution drafts and how they fit together.

Does the current process also include changes to text that has no real impact on the functionality of the module, e.g. descriptions? There was no clear answer to that question but the current way this is mostly understood is that any change to a YANG module, even descriptions or white space changes, would count as a change to the YANG module, requiring a revision.

Disposition: Agreed (informally, none dissenting) to suggest for IEEE 802.1 to follow the strict procedure IETF uses for changes on YANG modules, i.e. any change to a YANG module requires a revision of this YANG module.

5. Issues in Focus: Pretty Printing Discussion. The YANGsters Chair led the discussion per slides 7-8 of the presentation in agenda item 3.

Currently there is some bad formatting in ieee802-dot1x-types.yang.

A pretty printing tool (called “YANG Pretty Printer” per Johannes Specht’s “YANG Pretty Printer Introduction” http://www.ieee802.org/1/files/public/docs2020/new-specht-yang-pretty-printing-0620-v04.pdf) to avoid bad formatting in YANG modules is expected in the future.

IEEE SA Editors need to be included in the discussion of the workflow, including the pretty printing.

It needs to be made clear to IEEE SA Editors that pretty printing is not just intended to make the YANG modules look uniform but rather to make them human readable.

Disposition: Agreed (informally, none dissenting) to include the use of the Pretty Printer in the workflow of creating YANG modules in IEEE 802.1 projects. IEEE SA Editors need to be included in the discussion of defining the specific process.

6. Issues in Focus: Transmission Selection Algorithm YANG design discussion. The YANGsters Chair led the discussion per slide 6 of the presentation in agenda item 3.

Currently there is no way to set a Transmission Selection Algorithm (TSA) for a specific traffic class in a YANG module.

There are two proposals: to use a uint8 or to use identities.

It was pointed out that it should not be uint8 but rather uint32.

Disposition: Agreed (informally, none dissenting) to use identities for this.

7. Issues in Focus: I2RS Review. The YANGsters Chair led the discussion per slides 11-12 of the presentation in agenda item 3.

“A YANG Data Model for Layer 2 Network Topologies” https://tools.ietf.org/html/draft-ietf-i2rs-yang-l2-network-topology-14 references some IEEE 802.1 standards.

A request has been made by the IETF document shepherd and other interested parties to get a YANGsters review of the document and the YANG modules, before the document becomes an RFC.

The request was on short notice so it has not yet been satisfied.

The YANGsters Chair has started a discussion on the 802 YANG Email list that is ongoing.

Feedback is expected to be provided to IETF following further discussion.

The YANGsters Chair is expected to provide a list with topics to be reviewed for that purpose.

The topics are planned to be discussed in the Jul 28, 2020 YANGsters meeting.

Disposition: Agreed (informally, none dissenting) to provide a response to IETF following YANGsters discussion.

8. Issues in Focus: IANA YANG update. The YANGsters Chair led the discussion per slides 9-10 of the presentation in agenda item 3.

The iana-if-type YANG module in the YANG Catalog’s GitHub repository is out of date.

The YANG module should be automatically generated whenever the Interface Types table is updated in the IANA registry https://www.iana.org/assignments/smi-numbers/smi-numbers.xhtml.

This is a known issue that is expected to be fixed in the near future.

Disposition: Noted for information.

9. Update on Hot Issues. The YANGsters Chair presented the issues in the “YANGsters Issue List” https://1.ieee802.org/yangsters/yangsters-issue-list/.

A press release for IEEE Std 802.1Qcx was discussed.

Text for this press release needs to be created before it can be discussed and wordsmithed in the subgroup.

The next opportunity to do this is during the September 2020 interim session.

The press release would be discussed in the Aug 4, 2020 YANGsters meeting.

P802f was discussed.

An initial editor’s draft is being created. The draft is expected to include material describing possible new fields to be included in the registry, e.g. “friendly” names.

The proposed changes to the registry would be discussed with the Registration Authority Committee (RAC).

Disposition: Agreed (informally, none dissenting) that the RAC needs to be involved if additional fields to the registry are proposed.

10. Continue Maintenance/Guidelines Discussion. The discussion of open maintenance items in http://www.ieee802.org/1/files/public/docs2019/maint-specht-yang-comments-0919-v01.pdf was deferred by lack of time to a future YANGsters meeting.

Disposition: Agreed (informally, none dissenting) to schedule discussion of this agenda item in the Aug 11, 2020 YANGsters meeting.

11. Motions for further YANGsters meetings. The YANGsters Chair presented a draft for a motion slide to allow YANGsters to hold further weekly electronic meetings every Tuesday 10:00 – 11:00 AM ET, starting Jul 28, 2020.

Disposition: Agreed (informally, none dissenting) to have the presented motion in the closing plenary meeting.

12. Any Other Business. No other business was discussed by YANGsters in this session.

13. Future meetings. YANGsters meet next during the September 2020 IEEE 802.1 session.
