如何使用testpmd

testpmd的测试脚本

root@ubuntu241-192-168-10-241:~# cat start-test.sh

export DPDK_DIR=/root/dpdk/dpdk-17.11

export DPDK_TARGET=x86_64-native-linuxapp-gcc

export DPDK_BUILD=$DPDK_DIR/$DPDK_TARGET

export RTE_SDK=$DPDK_DIR

export RTE_TARGET=$DPDK_TARGET

mkdir -p /dev/hugepages

mount -t hugetlbfs hugetlbfs /dev/hugepages

modprobe uio

insmod $DPDK_BUILD/kmod/igb_uio.ko

$DPDK_DIR/usertools/dpdk-devbind.py --status

$DPDK_DIR/usertools/dpdk-devbind.py -b igb_uio 0000:00:03.0

cd /root/dpdk/dpdk-17.11/app/test-pmd

./testpmd -l 1,2,3 -n 2  -- -i --rxq=4 --txq=4

启动后的配置与查看

testpmd> set fwd txonly

testpmd> start

查看模式

testpmd> show config fwd

启动

testpmd> start

停止

testpmd> stop

查看结果

testpmd> show port stats all

设置模式

set fwd rxonly

set fwd txonly

set fwd io
