Dave,
You were right on the ball. I realized, I didn't have latest DPDK installed which is the root cause. I installed latest DPDK on my machine using the instructions here: https://core.dpdk.org/doc/quick-start/ Now the interface are seen in vpp once I shut them down in linux. $ sudo ./build-root/install-vpp-native/vpp/bin/vpp unix interactive vlib_pci_bind_to_uio: Skipping PCI device 0000:00:19.0 as host interface eth0 is updpdk [warn ]: not enough DPDK crypto resources dpdk/cryptodev [warn ]: dpdk_cryptodev_init: Not enough cryptodevs vat-plug/load [error ]: vat_plugin_register: oddbuf plugin not loaded... _______ _ _ _____ ___ __/ __/ _ \ (_)__ | | / / _ \/ _ \ _/ _// // / / / _ \ | |/ / ___/ ___/ /_/ /____(_)_/\___/ |___/_/ /_/ vpp# sh interface Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count GigabitEthernet1/0/0 1 down 9000/0/0/0 GigabitEthernet3/0/0 2 down 9000/0/0/0 GigabitEthernet3/0/1 3 down 9000/0/0/0 local0 0 down 0/0/0/0 vpp# thanks, Hemant From: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> On Behalf Of Dave Barach Sent: Sunday, December 06, 2020 7:49 AM To: hem...@mnkcg.com; vpp-dev@lists.fd.io Subject: Re: [vpp-dev] don't see any interface but local0 Most likely, the corresponding Linux interface is up. Try running vpp manually from the command-line, and look for messages of this form: vlib_pci_bind_to_uio: Skipping PCI device 0000:00:1f.6 as host interface eno2 is up vlib_pci_bind_to_uio: Skipping PCI device 0000:02:00.0 as host interface enp2s0f0 is up vlib_pci_bind_to_uio: Skipping PCI device 0000:02:00.1 as host interface enp2s0f1 is up vlib_pci_bind_to_uio: Skipping PCI device 0000:03:00.0 as host interface enp3s0f0 is up We should change pci.c to put these messages in the vlib log.
