[dpdk-users] error while launching dpdk-pdump with ovs-dpdk setup

[Murali Krishna]

Hello Everyone,



I am trying to capture packets using dpdk-pdump in ovs-dpdk environment.



I am using dpdk-17.11 and openvswitch 2.9.3, I enabled below config options
in dpdk/common/config_base.



CONFIG_RTE_LIBRTE_PMD_PCAP=y

CONFIG_RTE_LIBRTE_PDUMP=y



Configured ovs bridge with one dpdk port



I am getting below error while launching dpdk-dpump.

port=0,queue=*,rx-dev=/tmp/pkts.pcap
--server-socket-path=/usr/local/var/run/openvswitch
