This solves below reported issue. 2)And also make sure l3fwd application initializes packet capture framework by calling rte_pdump_init () api from its main(). Also should call uninitialize api rte_pdump_uninit() before exiting l3fwd application. Please refer app/test-pmd/testpmd.c file to see how these apis are used. Ex: int main(int argc, char** argv) { »·······int diag; »·······uint8_t port_id; »·······signal(SIGINT, signal_handler); »·······signal(SIGTERM, signal_handler); »·······diag = rte_eal_init(argc, argv); »·······if (diag < 0) »·······»·······rte_panic("Cannot init EAL\n"); #ifdef RTE_LIBRTE_PDUMP »·······/* initialize packet capture framework */ »·······rte_pdump_init(NULL); static void signal_handler(int signum) { »·······if (signum == SIGINT || signum == SIGTERM) { »·······»·······printf("\nSignal %d received, preparing to exit...\n", »·······»·······»·······»·······signum); #ifdef RTE_LIBRTE_PDUMP »·······»·······/* uninitialize packet capture framework */ »·······»·······rte_pdump_uninit(); #endif 3)As of now initializing and un initializing of the packet capture framework is done only in testpmd, for other applications this is not done. We left users to do this for now. Please feel free to ping me if you see some more issues.

This solves below reported issue. 2)And also make sure l3fwd application initializes packet capture framework by calling rte_pdump_init () api from its main(). Also should call uninitialize api rte_pdump_uninit() before exiting l3fwd application. Please refer app/test-pmd/testpmd.c file to see how these apis are used. Ex: int main(int argc, char** argv) { »·······int diag; »·······uint8_t port_id; »·······signal(SIGINT, signal_handler); »·······signal(SIGTERM, signal_handler); »·······diag = rte_eal_init(argc, argv); »·······if (diag < 0) »·······»·······rte_panic("Cannot init EAL\n"); #ifdef RTE_LIBRTE_PDUMP »·······/* initialize packet capture framework */ »·······rte_pdump_init(NULL); static void signal_handler(int signum) { »·······if (signum == SIGINT || signum == SIGTERM) { »·······»·······printf("\nSignal %d received, preparing to exit...\n", »·······»·······»·······»·······signum); #ifdef RTE_LIBRTE_PDUMP »·······»·······/* uninitialize packet capture framework */ »·······»·······rte_pdump_uninit(); #endif 3)As of now initializing and un initializing of the packet capture framework is done only in testpmd, for other applications this is not done.

This solves below reported issue. 2)And also make sure l3fwd application initializes packet capture framework by calling rte_pdump_init () api from its main(). Also should call uninitialize api rte_pdump_uninit() before exiting l3fwd application. Please refer app/test-pmd/testpmd.c file to see how these apis are used. Ex: int main(int argc, char** argv) { »·······int diag; »·······uint8_t port_id; »·······signal(SIGINT, signal_handler); »·······signal(SIGTERM, signal_handler); »·······diag = rte_eal_init(argc, argv); »·······if (diag < 0) »·······»·······rte_panic("Cannot init EAL\n"); #ifdef RTE_LIBRTE_PDUMP »·······/* initialize packet capture framework */ »·······rte_pdump_init(NULL); static void signal_handler(int signum) { »·······if (signum == SIGINT || signum == SIGTERM) { »·······»·······printf("\nSignal %d received, preparing to exit...\n", »·······»·······»·······»·······signum); #ifdef RTE_LIBRTE_PDUMP »·······»·······/* uninitialize packet capture framework */ »·······»·······rte_pdump_uninit(); #endif 3)As of now initializing and un initializing of the packet capture framework is done only in testpmd, for other applications this is not done.

Not sure what exactly is the issue behind this. But as of now i did 2 things, in place of running setup.sh, i tried to give make command, with DESTDIR. Now i got exe. So if i execute the dpdk_pdump from this folder(destination directory that i gave at the time of building DPDK), it is working fine. But if i go in ./dpdk/app/pdump, build app here and then try to run it is not working. Ok, I will check this issue and fix if it is a bug. That is good that you could run from DESTDIR, I always ran from DESTDIR. 2. Even their is no packet to capture, it showing error "insufficient data_len of mbuf" this is how i run and end pdump execution. " The mbuf-size that you pass to dpdk_pdump command should be same or greater than the mbuf size that was used for mempool creation for the Rx packets inside the primary application. Ex: in L3fwd, the size used is RTE_MBUF_DEFAULT_BUF_SIZE. rte_pktmbuf_pool_create(s, nb_mbuf, MEMPOOL_CACHE_SIZE, 0, RTE_MBUF_DEFAULT_BUF_SIZE, socketid); If you know that value you can pass it on, else I suggest don’t pass any value, then dpdk_pdump will use default mbuf size internally i.e. (RTE_MBUF_DEFAULT_BUF_SIZE). Here you are using mbuf-size 20 which is far less than the what l3fwd is using, hence pdump library will throw this error in such cases. Try suggested points and let me know if you see any more issues. root@ubuntu:/home/oneweb/dpdk/install/bin# ./dpdk_pdump --file-prefix l3f -- --pdump 'port=0,queue=*,rx-dev=/tmp/rx-file.pcap,tx-dev=/tmp/tx-file.pcap,ring-size=1024,mbuf-size=20,total-num-mbufs=1025' EAL: Detected 16 lcore(s) EAL: Probing VFIO support...

So you need to install libpcap package and set CONFIG_RTE_LIBRTE_PMD_PCAP flag to “y” in config/common_base file and recompile the DPDK and run pdump tool. Please let me know if that fix the issue.
