The device is an ixgbe ethernet device with fiber connection. # ifconfig p1p1 | grep Ethernet p1p1 Link encap:Ethernet HWaddr (removed) # lspci -v 01:00.1 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) Subsystem: Intel Corporation Ethernet Server Adapter X520-2 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at c5180000 (64-bit, prefetchable) [size=512K] I/O ports at 2000 [size=32] Memory at c5204000 (64-bit, prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+ Capabilities: [70] MSI-X: Enable+ Count=64 Masked- Capabilities: [a0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [140] Device Serial Number (removed) Capabilities: [150] Alternative Routing-ID Interpretation (ARI) Capabilities: [160] Single Root I/O Virtualization (SR-IOV) Kernel driver in use: ixgbe Kernel modules: ixgbe >Are there any "ethX" devices available that you >can use for your test? I don’t have any eth* devices on this box, probably due to the ‘consistent network device naming’ convention, but I have ‘emX’ (igb) devices, and those work fine. However, I need to send traffic out the ixgbe device, so that doesn’t help me. Please note that tcpreplay-3.4.4 recognizes the p1p1 device fine and it works fine. I’ve only encountered this behavior with the 4.0.3 release. Here’s a reference to the naming standard in use across RHEL and more recent Fedoras which is probably what’s leading to the p1p1 names: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux /6/html/Deployment_Guide/appe-Consistent_Network_Device_Naming.html >Finally, is this on a real or virtual machine?
