[ovs-discuss] Cannot dump packet capture using dpdk-pdump

[Sun Paul]

Hi

I am trying to configured dpdk-pdump to dump the packet in the OVS
bridge, however, I am failed. no packet is capture on ingress or
egress, any idea?


the command I used is
./dpdk-pdump -- --pdump
port=1,queue=*,rx-dev=/tmp/pkts_rx.pcap,tx-dev=/tmp/pkts_tx.pcap
--server-socket-path=/usr/local/var/run/openvswitch

the output on the screen is shown below.
