Hi,  
This is coreset I configure in dpdk:  
dpdk:  
eal-params:  
proc-type: primary  
l: “32,34,36,38,40,42,44,46,48,50,52,54”  
And this is worker-cpu-set I configured:  
- worker-cpu-set:  
cpu: [29,31,33,35,37,39,41,43,45,47,49,51,53,55]  
mode: “exclusive”  
# Use explicitly 3 threads and don’t compute number by using  
# detect-thread-ratio variable:  
#threads: 3  
When I start suricata,I get this:

The configure " l: “32,34,36,38,40,42,44,46,48,50,52,54"” doesn‘t work?  
thanks!

Hello, no, sorry doesn’t use DPDK lcores so any lcore EAL parameter doesn’t have an effect. Please only specify worker/management CPU cores.
