[dpdk-dev] testpmd: not seeing any traffic on 1g (pair) or 10g pair

[Zhou, Danny]

The .log below shows your two 10G ports link are up. 

Which CPU are you using now and how many processor sockets do you have? If you used a platform with two processor sockets, make sure to use correct core mask to specify cores rx/tx packets from 10G NIC connecting to local socket. For you case, make sure 10G NIC with BNF 0e:00.0/0e:00.1 connects to CPU socket No.0(as you used -c 0xF to use core 0 to 3 on socket No.0), otherwise you have to change the core mask in the command line to use logical cores on socket No.1.
