Understood...
Usually I use show run to monitor packet drops. Do you have another suggestion for me to get a more precise information about it?

I think what we have set as default is reasonable and you should leave it unless you are experiencing some issues… — Damjan On 14.04.2021., at 13:45, Marcos - Mgiga <mar...@mgiga.com.br <mailto:mar...@mgiga.com.br> > wrote: Hello Damjan, Thank you for clarifying... I also have a question about num-rx-desc and num-rt-desc parameters, hope you dont mind to dicuss it in this e-mail I would like to understand what value fits better to my environment, do have any thoughts about it?

Since VPP is running on a NUMA system with two threads with 8 cores each, I would like to pin TX / RX queue to proper NUMA nodes. Using set interface rx-placement I was able to associate rx queue to desired cores, so I would like to know if is there any possibility to pin tx queue to a certain workers as well. Not at the moment. tx queues are statically mapped (0 to main thread, 1 to worker 0, 2 to worker 1, etc.). There are some plans to implement such capability…..
