- clear hardware counter drop - show hardware counter drop
- clear counter - show cpu counter queue
- start traffic, and repeat trigger or test case, hold for some time then stop traffic
- check drop counter:
- show hard counter drop
- show cpu counter queue | nz

CpuQueueL3DstMiss means, 1) unresolved ipv4 arp; 2) unresolved ipv6 neighbor.

Finally it turns out that I missed the vxlan config.
