CRS328-24P-4S+RM profiler: "spi" usage

Tue Feb 23, 2021 5:02 am

I see all the time ~3% "spi" usage in /tool profile on brand new CRS328-24P-4S+RM. Never saw this on rest of my devices before: CRS326-24G, CRS317, CCR2004, RB4011, ... so I'm just curious what is causing this. If "spi" is related to internal flash, from my point of view this should not happen on simple L2 switch with almost zero flash writes.

Currently there is only one PoE device connected:
> /interface ethernet poe monitor ether21
             name: ether21
          poe-out: auto-on
      poe-voltage: auto
   poe-out-status: powered-on
  poe-out-voltage: 52.3V
  poe-out-current: 94mA
    poe-out-power: 4.9W
System info:
