[f-nsp] Unexpected CPU load on NetIron CER

[Bardo Cornelissen]

Hi folks,

 

I have recently installed a NetIron CER 2024F-4X and at implementation I saw
relatively high CPU levels when using "route-only" on specifically an 10G
(AMS-IX Exchange) port. "sh cpu lp" showed values at around 50% and icmp
traffic on the router ip showed packetloss. When I turn of "route-only" the
cpu utilization drops to 9-10% and stays stable.

 

I still find these values high. We previously used an old jetcore router
with the same settings and that had a stable 1% cpu-utilization. It feels
some sort of traffic is causing load on the cpu but so far I've not been
able to track down the issue. Has anyone seen similar behavior?

SLOT  #:          LP CPU UTILIZATION in  %:

               in 1 second:  in 5 seconds:  in 60 seconds: in 300 seconds:

     1:        10            9              9               9

     2:        10            9              9               9

 

Kind regards,
