Hi Team,

I was trying to install DPDK-Pktgen(Pktgen version 2.7.7 using
DPDK-1.7.1) for testing 10G Ethernet ports using NIC card, with 4
cores(1: Kernel 1:logs for pktgen 2:for Tx Rx of traffic).

But i was ending up with "*** Did not find any ports to use ***" while I was using the below mentioned command

Command:
--------
./app/build/pktgen -c 0x0c -n 3 --proc-type auto -m 512 --file-prefix pg
-- -T -P -m "2.0,3.1"
collected logs are as below...

On googling i found the issues might be due to binding and when i tried the below steps i was ending up with binding failed and logs are as below

[root at localhost tools]# ./dpdk_nic_bind.py --status
