Unable to capture data packets using Wireshark from mellanox card

Hi,

I am using 40Gb Mellanox card. Capturing the data packets with DPDK.

Using testpmd+pdump successfully captured the pkts from 40Gb.

However replicate the same using Wireshark+testpmd, am not able to capture the data packets. Msg displayed is NO PACKETS from the mellanox interface.

Do I need to use any specific settings to use this combination ?

Working on

Ubuntu 18

DPDK 19

Wireshark 3

Mellnox mlx5 40G capacity

Thanks

Katie

Hi,

To capture packets with DPDK, you have to use a special tool and not wireshark that capture packets going through the standard IP stack only

Please see the following link:

https://doc.dpdk.org/guides/howto/packet_capture_framework.html

In addition, there’s some wireshark forum that asked for support of dpdk device capturing and this is the link:
