Agenda

  • New topics
    • Review C-release feature issue list
      • what should be in the dentOS released images?
      • what is the C-release?
        • configuration management
          • baby step: write a CLI config file manager for networkd
            • networkd is likely best choice to persist interface states
            • networkd has no built in support for writing config files
            • ndcfg network network_name Match MACAddress aa.bb.cc.dd.ee.ff Network DHCP yes
            • ndcfg network rm -y network_name
            • ndcfg link link_name Match OriginalName sw1p15 Link MTUBytes 9000
            • zero potential this could be accepted upstream into networkctl but we should investigate potential. systemd dbus interface can't push configs into systemd.
          • gNMI
            • has open implementation in SONiC
            • contributed to IETF
            • @jon leans heavily towards gNMI
            • gRPC based
            • protobuf for exchange
            • http transport
            • reference implementations in go
            • go may have lower barrier to entry for development/extension
            • not tied to yang so forces less opinions onto user
          • yang, netconf, resconf
            • sysrepo is available as open implementation
            • netconf uses xml encoding which dates it
            • netconf is its own protocol; does not ride on http
            • existing open implementations as C libraries
        • security
          • 802.1x
            • test trap of 0x888E with tc filter rule
            • what to do for authenticator daemon?
            • how to handle MAB for clients that can't do EAP
          • STP
            • networkd can't enable BPDU guard?
            • UseBPDU= maybe?
            • NetworkManager only has simple STP on/off settings for bridge
          • DHCP snooping
          • Port isolation/private VLAN
        • base platform
          • Debian or Gentoo most likely
          • Which one is most flexible?
      • Build system
        • Propose to move dentOS to replica for build system
    • identify features that need a decision point
      • wireguard (strong interest/use potential in this)
      • telemetry
      • IGMP snooping
      • Port security
      • new userspace daemon for dot1x
    • project goals discussion
      • what is main objective of DENT project?
      • how best can we enable the user to accomplish their goals/desires with "products" of the DENT project/community?
    • "ONLP rewrite to use kernel subsystems"
      • is this the best path to invest in?
      • Setup follow-up meeting to discuss userspace platform management tools (IE: what ONLP does now)
      • Take a high level look at what makes sense across wired switches, wireless APs, and any other device types the DENT project may want to support
      • Steve Noble thinks ONLP shim is possible and best option at least in short term
      • Sartura doesn't like obtrusiveness and complexity of ONLP and suggests examination of what is minimally required to expose enough functionality for end users to develop exactly what they need
      • Mellanox does not use ONLP on Spectrum platforms
      • Participants: nvidia, Sartura, amazon, ODMs [Delta, Accton, WNC]

Actions

  • Delta to provide PoE controller software specification
  • Amazon to supply PoE daemon specifications for external contributors (Carl Roth)
  • Need to develop specification for 802.1x driver portion
  • Develop vendor agnostic driver feature requirements list
  • Marvell will update Prestera Switchdev wiki with current features (in process)
  • Create github issue in dentOS repo for platform support model discussion
