Hi Arix,

 

Looks like your Junos Verison is exposed to this issue. You can safely ignore them or filter them using below config

 

set system syslog file messages match “!(pkt rx on ifd NULL)”

Hi Arix,

 

These logs should be happening as a result of vc-packets which get flooded to internal HG-port. Since these HG ports do not have a port number, it is expected to reflect as NULL. This issue is not fixed in junos which you are running currently.

 

As per the PR#1381151. This issue should be fixed in junos

18.2R3 , 18.4R2

 

 

Regards,

Akash

hi all,

 

Can I ask about the following terms:

  • dc-pfe (I know pfe but not dc)
  • vc-packets
  • internal HG portth

Thx

vc-packets - VC Control packets (I think!) vs user data packets that travel across any VC connection

HG - High-Gig: Internal protocol or function that provides VC support.  HG (BCM term) and VC (Juniper term) can be used interchangeably, sort of.

Just posting that im seeing the same issues with junos-arm-32-18.3R1-S4.1

Noticed eventd is eating up all the free CPU cycles on RE.

Going to wait and see if R2 when released addresses the issue as posted in PR
