[OA] admin-disable port before setPortSerdesAttribute()

Open amnsinghal opened this issue 2 years ago • 0 comments

Admin-disable port before setPortSerdesAttribute() to maintain deterministic link behavior during media_settings notification from xcvrd to OA/syncd. This will trigger CMIS FSM re-init and ensure that Optics retune to modified NPU serdes signal.

Scenarios to consider, in addition to fresh bootup (or reboot):

  1. xcvrd process crash
  2. pmon docker restart
  3. syncd/swss docker restart
  4. OA process crash
  5. config reload
