Hi Jonathan 😊,
During the execution of the dpdk-replay tool, we encountered the following message:
port 0 is not on the good numa id (-1)
This appears to be an informational warning, typically generated when DPDK cannot determine the NUMA node for the PCI device. According to discussions on the DPDK stable mailing list, this warning is benign and does not affect functionality or performance—especially for NICs like Intel I225/I210 that do not report NUMA affinity.
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.
Observation:
Despite successful file reading and replay initiation, we did not observe any frames being transmitted or received on either the sender or the receiver side.
Could you please advise if there are any additional steps or configurations we should verify?

Best regards,
