Hi again Reshma
I worked on testpmd and below is the output of testpmd command in dpdk-setup.sh script (number 28 in the list)  :

and here is the output od dpdk-pdump command , it is stiil ruunin gbut not creating rx.pcap file

After above logs you should be seeing  logs similar to below ones.

PMD: Initializing pmd_pcap for eth_pcap_rx_0
PMD: Creating pcap-backed ethdev on numa socket 0
Port 2 MAC: 00 00 00 01 02 03

Since you are not seeing, I guess dpdk-pdump tool  might have got stuck in the code somewhere.
Can you just add some  debug prints  after the below if condition in the file app/pdump/main.c, there are  3 such if conditions, so add prints at all 3 places.
Compile the dpdk-pdump again , run and give me the startup logs.

if (rte_eth_dev_attach(vdev_args,
&portid) < 0) {
cleanup_rings();
rte_exit(EXIT_FAILURE,
"vdev creation failed:"
"%s:%d\n", __func__, __LINE__);
}
<add printf here>
[Reshma 2]:
Can you provide the output of “rpm -qa | grep pcap”

[Reshma 3]:
Can you give the output of “grep CONFIG_RTE_LIBRTE_PMD_PCAP config/common_base”

Thanks,
Reshma

I have no idea what is the problem!

Hi Reshma
Sory for delay in response ,I change the OS system of my server and I am working to set up DPDK again from the base !
I will send the startup logs of testpmd and dpdk-pdump as soon as posible!
thank you very much

Hi ,

Resending the mail again.. Can you provide me below info to help you in finding the issue?
Do you have libpcap development files  installed on your machine.?
Can you send me the startup logs of testpmd and dpdk-pdump tool. I will take a look.

Thanks,
Reshma

I assume you are running testpmd first and then dpdk-pdump tool, is that correct?
Also I see you are using rx-dev as rx-1-file.pcap but not rx.pcap file. So you should look for file
rx-1-file.pcap but not rx.pcap, or is that a typo in your sentence?
