Short answer: not as the code stands today. 

 

It would be simple to augment pcap_sw_if_index with a bitmap to solve “n choose 
k” problems.

 

Making the scheme multi-instance would involve a significant rework, and 
effectively discards packet processing order information. I wouldn’t be in 
favor of that one.

 

FWIW... Dave

Subject: [vpp-dev] VPP 2106 How to enable Pcap trace of 2 interfaces out of 4

 

Hi ,

 

We have to enable pcap trace for two interfaces out of four VPP interfaces  and 
in separate pcap files, Is it possible with pcap trace CLI to run it parallel 
with multiple instances?  

 

Regards,

Sunil
