Hi Team,

I’m currently working with the dpdk-burst-replay tool and encountered an issue during execution. Below are the details:

---

Observation:
During replay, we received the following informational message:

port 0 is not on the good numa id (-1)

As per the DPDK mailing list discussions, this warning is typically benign—often seen on NICs like Intel I225/I210, which do not report NUMA affinity. Hence, we proceeded with execution.

---

Command Used:

sudo numactl --cpunodebind=0 --membind=0 ./src/dpdk-replay Original_MAC.pcap 0000:01:00.1

Execution Output:

preloading Original_MAC.pcap file (of size: 143959 bytes)

file read at 100.00%

read 675 pkts (for a total of 143959 bytes). max packet length = 1518 bytes.

-> Needed MBUF size: 1648

-> Needed number of MBUFs: 675

-> Needed Memory = 1.061 MB

-> Needed Hugepages of 1 GB = 1

-> Needed CPUs: 1

-> Create mempool of 675 mbufs of 1648 octets.

-> Will cache 675 pkts on 1 caches.

---

Issue:
Despite successful parsing of the pcap file and proper initialization, no frames were transmitted or received on either the sender or receiver sides.

---

Environment Details:

• NIC used: Intel I225/I210
• Hugepages configured: 1 GB
• NUMA binding: --cpunodebind=0 --membind=0
• OS: [Your Linux distribution, e.g., Ubuntu 20.04]
• DPDK version: [Mention if known]

---

Could you please advise if any additional setup, configuration, or known limitations may be impacting the packet transmission?

Thank you in advance for your support!

Best regards,
Gokul K R
