  • MoM of today's OCP SONiC call  10/15/2019.

Topics discussed
  • Tech Support export Service 
Review (Q & A):
  • Can custom scripts will be added to tech support service ? This is minimal service, can be added. 
  • Can the Journal data should be part of tech support ? will be included
  • What kind of granular level support provided by tech support service? Minimal service for now, can be added filters, custom plugins to ex: to export to cloud etc. 
  • It seems tech support keep adding repeated data? How to avoid this storage back pressure on remote server? will look it
  • do you have per process core support ? Can the user cherry pick on few process instead all ? With current schema of things with containers seems not possible right now. BRCM will look into it.
  •   Core File Manager 
Review (Q & A):
  • Can File Manager do automatic analysis on core dumps ? yes 
  • Will it be possible to export only analysis reports to tech support ? yes 
  • Is the Core file uploaded with back traces ? yes
  • Does the systemD increase footprint - little bit 
Thanks,
Madhu

    Topics discussed
    • Dynamic Port BreakOut HLD - LNKD 
    Review (Q & A):
    • Can't SONiC query SAI API to fetch the break out capabilities?
    • Generic question : Why breakout support only per interface? why can' t it per device ? Platform's don't allow certain ports due to silicon issues or the feature is not ready to use the breakout port on this relesase
    • Can the breakout feature supports range of ports together? 
    • Can ASIC vendors support breakout on range/group of ports?
    • What does platform vendors do to support this feature?  It seems vendors should provide platforms.ini file.
    • Can this feature support the list of breakout supported to the user? 
    • Can breakout feature enforce lanes and aliases to the sonic application?
    • Why can't we define platform files per HWSKU?  
    • Can this HLD covers Platform LED feature?
    • How about the configuration validations during port-breakout ? Can this integrate with MGMT framework CVL lib? yes.

      Topics discussed

      • VRF design discussion  - Nephos (Jeffrey) 
      Review (Q&A)
      • How does VRF configures in Linux kernel? As of now, though there is a CLI wrapper, SONiC ultimately uses the linux NetLink calls. [Community has some suggestions - Liat may help here with our examples]
      • Questions on config_db migration script on VRF config migration? offline discussions would continue/PR feedback.
      • Design decision behind creating an empty interface INTERFACE|Ethernet0:{} in config_db ? Multiple things, 1) SAI 2) Code complexity behind the resource migration. etc. There is a section in the PR,  feedback can be provided.
      • There is a request on VRF ID adding besides interface name in the next hop? The decision seems we are going with minimal configuration to support the SONiC system design.
      • Can we safely assume VRF design supports later versions of Linux Kernel 4.9? Yes. 
      What next? 
      • PR discussion could be extended to next meeting based on the PR feedback. [Jeffery/Prince]

      MoM of today's OCP SONiC call  06/18/2019.

      Topics discussed

      • Error Handling  - BRCM (Santhosh)
      Review (Q&A)
      We had a great discussion, there are lot of inputs from community and here is some. Feel free to add missing comments here.
      • How does framework supports multiple CRUD failures?  
      [Ben]: See below 
      • Do you provide a knob to switch off Error handling feature? Is knob necessary? 
      [Ben]: No knob is necessary. The error handling proposal is a framework that is available for a) implementation of error reporting in SWSS on a feature-by-feature basis and b) application processing of such errors. Both a) and b) are implementation choices that can be made on an feature-by-feature basis. And if an application does not want to process a supported error, then it can just ignore it. 
      • Does the applications get out of order notifications from feedback loop? How to handle in the case of it? Ex: User does create/delete/create and do you expect the error feedback come in order? 
      [Ben]: The specific comment was that the key/values used to refer to APP_DB (or other) in an ERROR_DB report may not be specific enough to distinguish between different error events. The example given (by Nikos) was a route add-withdraw-add case - since the APP_DB table entry may be the same between the 2 adds, then, if there's an error report, how does the application (FRR in this case) know which of the adds failed? We will come back on this point. 
      • What is the design decision behind a new Error DB? Why can't we merge error attributes into APP DB? 
      [Ben]: We thought about both options, and decided that the ERROR_DB gave a bit more flexibility and avoided changing existing application tables. It was not a clear decision, but we see no reason to move away from it. 
      • What is the mechanism to synchronize route CRUD between APP DB vs new Error DB? 
      [Ben]: See above 
      • Is new Error DB is a mirror of APP DB? 
      [Ben]: Not really - but each error table entry points to a corresponding entry in another table (usually APP_DB) 
      • The current design mentioned an approach to stop propagate the failed/error routes to the neighbors? This may not right as per RFC, the routes should propagate though the it failed due to some policy. (Nikos)
      [Ben]: This topic went beyond scope of the framework (#1 above) and into the BGP doc (#2). We will setup a separate offline discussion for this.
       
      Overall feedback - The feedback loop is necessary to address SAI fatal errors. However the community requested the design should dis associate/de couple the feedback loop  as much as possible so that applications have freedom to react/handle it own way.
      [Ben]: That's exactly how it's setup today. 
      one option suggested - Framework should more generic and should accommodate opaque error context for the applications. 
      [Ben]: This is a different topic - see above ("The specific comment was that the key/values ....")

      Xin will extend an offline discussion on this topic, stay tuned.

      Q & A 
      • Can this STP feature compile time disabled? BRCM will explore this (compile time/run time options to disable/enable STP/PVST feature)
      • Warm reboot not supported for PVST? Community requested more details need to be added to design 
      • Multiple questions what is the design decision on why  STP states are not programming to Kernel?   Few questions: 1) With the current STP design - the STP states are not populating in kernel, ASIC and Kernel will be out of sync, what is the downside ?  2) Let's say Port/Vlan is not blocking in the kernel, but is blocked in ASIC, then what is the behavior with arp/ping/ospf in this scenarios ?  BRCM should document the scenarios.
      • Community requested to document the ASIC and Kernel out of sync scenarios - AI BRCM
      • There should be no drop if HW says forwarding? yes
      • Is there mechanism to program the states in to Kernel ? BRCM to explore on it
      • If the trap is configured on port which is blocked does the packet comes to CPU? yes, based on the trap configurations.
      • When port is blocked in HW, what are the packets should send? - HW shouldn't block L2 packets/LACP exchanges but drop L3 packets.
      • Can COPP program to trap to cpu ? Yes
