Maintenance Task Group
Tuesday 15 January 2019
8:00 AM (call to order by the TG Chair) to 9:00 AM
The Maintenance Task Group Chair, Paul Congdon, presided and wrote the minutes.
At the beginning of the meeting the TG Chair presented the IEEE-SA PatCom Patent Slides for Standards Development Meetings https://development.standards.ieee.org/myproject/Public/mytools/mob/slideset.pdf, and made the Call for Potentially Essential Patents. There were no responses to the calls prior to the end of the meeting.
The TG Chair:
- Introduced the agenda that was approved.
- Presented the list of current vehicles (drafts) used for implementing maintenance items, and the current numerical status of maintenance items in the 802.1 maintenance database at https://www.802-1.org/items. Details in http://www.ieee802.org/1/files/public/docs2019/maint-congdon-session-0119-v02.pdf.
- Presented the items processed prior to the meeting. Several items were closed thanks to the publication of 802.1Xck-2018.
- Led the review and update of existing maintenance items.
- No action taken on 0170, 0174, 0205 and 210 because they are awaiting a document vehicle to be resolved and are otherwise ready to go.
- Led the discussion of two new maintenance items. A log of the discussion is kept in the 802.1 maintenance database and only unrelated discussion or action items follow:
- 0223 – IEEE8021-SRP-MIB inappropriate SYNTAX for ieee8021SrpStreamDataFramePriority
- 0224 – Clarify whether frame ends on last bit or after the inter-packet gap and preamble
- Confirmed no 802.1 WG comment resolution was needed.
- Led the review of the incoming liaison and document in http://www.ieee802.org/1/files/public/docs2019/liaison-SG15-LS172-OTNT_standardization_workplan-0119.zip, both of which were discussed.
- The WG Chair described the current process for updating ITU-T SG15 with 802.1 latest status, and will provide an update to ITU-T SG15 for their September 2019 meeting. There is no need to respond to this liaison, but the WG was asked to provide further review of the current ITU-T SG15 document and raise any concerns at the March 2019 plenary session.
- Led the review of a draft response and plan for responding to CN.1 of IEEE 802c-2017 (ISO/IEC/IEEE FDIS 8802- A:2015/FDAmd 2): see http://www.ieee802.org/1/files/public/docs2019/maint-randall-SC6CommentResponse802c-0119-v01.pdf.
- A response will be finalized at the March 2019 plenary session.
- It was pointed out that several additional arguments could be included in the response to strengthen the response. These include the fact that using an OID as a protocol identifier could cause protocol incompatibility with many existing protocols using CID and OUI today. Secondly, the SNAP encoding has been successfully using OUI for many years and replacing OUI with CID is completely compatible, whereas using OID would not map directly. An OID can be a variable length field which makes its use in protocol identifier fields problematic and complex for many implementations.
- Led the review of the status of standards in the SC6 engagement and PSDO process, prepared by Karen Randall.
- Led a discussion on how to progress YANG modules in the WG. Several ballot comments were rejected in November 2018 because they were considered enhancement requests and not bugs against 802.1Qcp. In November 2018, it was suggested that the submitter initiate an amendment project to update and improve the YANG module. There is concern that the overhead and process related to an amendment is too burdensome and it was asked if there is another approach to improve YANG modules. It was suggested that the discussion is related to the 802.1 Open Source strategy which is still evolving. The desire is to be more fluid and agile in developing ‘code’ such as YANG modules using the Open Source approach and tools such as github. There is a strong desire by everyone to streamline the process of developing ‘code’ such as YANG modules, and such a new process is in progress but not currently deployed.
- Post-meeting, provided updated session slides http://www.ieee802.org/1/files/public/docs2019/maint-congdon-session-0119-v02.pdf based on discussion. The TG website at http://www.ieee802.org/1/maint.html provides further details and discussion.

A conference call bridge was setup for remote participants.
P802.1CQ contributions and discussions
P802.1CQ requirements and scenarios documentation: no contributions for discussion
P802.1CQ security threats of dynamic local address assignment protocol: the following two contributions were discussed.
Antonio de la Oliva presented Analysis on new possibility [of] security threa[t]s in IEEE 802.1CQ https://mentor.ieee.org/omniran/dcn/19/omniran-19-0001-00-CQ00-ieee-802-1cq-threat-analysis.pdf to the TG and to the Security TG chair. Potential security threats were discussed.
Disposition:
- Recommendation not to mention potential vulnerabilities caused by inappropriate implementation of 802 standards.
- Such statements could lead to the wrong impression of security weaknesses in 802 standards.
- Conclusion that local address assignment does not cause any new threats in addition to threats arising due to inappropriate implementations of the LAAP and LAAP components.
- LAAP should avoid leakage of information through broadcast of responses, and should not add much overhead to the number of message exchanges for setting up a connection.
- Antonio de la Oliva will create text contribution out of presented material and discussions results.
Max Riegel presented MAC randomization impacts (WBA liaison to IEEE 802.11) https://mentor.ieee.org/omniran/dcn/19/omniran-19-0002-00-CQ00-random-mac-impact.pptx.
- Max Riegel provided a summary of MAC address usage as device identifier for network operations as brought up by WBA.
Disposition:
- Agreement reached that WBA use cases are legitimate reasons to provide the possibility to assign static device identifier to stations for initiating the dynamic MAC address assignment.
- Static device identifier allows LAAP to assign fixed MAC addresses to devices.
- Antonio de la Oliva will draft a protocol proposal for secure signaling of a static device identifier to the access network.
- Max Riegel will draft a section for the functional requirements describing the need to provide the possibility of fixed device identifiers.
Wednesday 16 January 2019
1:30 PM (call to order by the TG Chair) to 3:15 PM, with a 1-hour lunch break
Discussions about potential future work in OmniRAN

- This model was presented as simpler and more straightforward than the model under consideration in P60802.
- The presentation suggested this model could become the base of a generic model.
Disposition:
- Discussion showed good acceptance of the idea of a simpler model for data characterization for industrial applications.
- Satoko Itaya was encouraged to create a more comprehensive slide set for presentation to the IEC/IEEE 60802 Joint Project and to the TSN TG.

Günter Steindl presented IEC/IEEE 60802 – TSN-IA Profile Scope and Status http://www.ieee802.org/1/files/public/docs2019/60802-Steindl-ScopeAndStatus-0119-v02.pdf
Disposition: No further action required.
Post-meeting, the TG Chair pointed out that the “No online participation allowed!” statement of slide 15 is misleading because the TG holds bi-weekly online teleconferences together with IEC 65C/MT9 to progress IEC/IEEE P60802 that anyone is welcome to attend. The TG Chair’s interpretation of the intention behind the statement was that there is generally no remote participation to IEEE 802.1 face-to-face meetings (as opposed to some other organizations, e.g., the IETF). The presentation was updated as http://www.ieee802.org/1/files/public/docs2019/60802-Steindl-ScopeAndStatus-0119-v03.pdf.
