First create ``server`` interface::
- #./build/app/testpmd -l 0-1 --proc-type=primary --file-prefix=pmd1 --vdev=net_memif,role=server -- -i
+ #./<build_dir>/app/dpdk-testpmd -l 0-1 --proc-type=primary --file-prefix=pmd1 --vdev=net_memif,role=server -- -i
Now create ``client`` interface (server must be already running so the client will connect)::
- #./build/app/testpmd -l 2-3 --proc-type=primary --file-prefix=pmd2 --vdev=net_memif -- -i
+ #./<build_dir>/app/dpdk-testpmd -l 2-3 --proc-type=primary --file-prefix=pmd2 --vdev=net_memif -- -i
You can also enable ``zero-copy`` on ``client`` interface::
- #./build/app/testpmd -l 2-3 --proc-type=primary --file-prefix=pmd2 --vdev=net_memif,zero-copy=yes --single-file-segments -- -i
+ #./<build_dir>/app/dpdk-testpmd -l 2-3 --proc-type=primary --file-prefix=pmd2 --vdev=net_memif,zero-copy=yes --single-file-segments -- -i
Start forwarding packets::
Now create memif interface by running testpmd with these command line options::
- #./testpmd --vdev=net_memif,socket=/run/vpp/memif.sock -- -i
+ #./dpdk-testpmd --vdev=net_memif,socket=/run/vpp/memif.sock -- -i
Testpmd should now create memif client interface and try to connect to server.
In testpmd set forward option to icmpecho and start forwarding::
To set the loopback, just use the same socket and id with different roles::
- #./testpmd --vdev=net_memif0,role=server,id=0 --vdev=net_memif1,role=client,id=0 -- -i
+ #./dpdk-testpmd --vdev=net_memif0,role=server,id=0 --vdev=net_memif1,role=client,id=0 -- -i
Then start the communication::
