Step 7: Configure the NIC ports which will be managed by DPDK
# ip link set <PORT 1> down
# ip link set <PORT 2>down
# ip link set <PORT 3> down
# ip link set <PORT 4> down
# dpdk-devbind-atom-latest.py -b igb_uio < PORT 1 PFA >
# dpdk-devbind-atom-latest.py -b igb_uio < PORT 2 PFA >
# dpdk-devbind-atom-latest.py -b igb_uio < PORT 3 PFA >
# dpdk-devbind-atom-latest.py -b igb_uio < PORT 4 PFA >
Step 8: Make a soft link to current folder as running binary 'pktgen-dpdk-wr-atom-latest'
requires this link
# ln -sf /root/bin/Pktgen-atom-latest.lua `pwd`/Pktgen.lua
Step 9: Start Pktgen program
# pktgen-dpdk-wr-atom-latest --master-lcore <ID> -c < COREMASK > -n <CHANNELS > -w <
PORT 1 PFA > -w < PORT 2 PFA > --socket-mem=<MEM SIZE> --file-prefix=dpdk_pktgen -- -P -
T -m <MATRIX >
If the program runs successfully, users shall end up with Pktgen CLI (c.f. Figure 2934: Pktgen
CLI)
Step 10: Open another SSH connection
Step 11: start l3fwd program
# l3fwd-atom-latest --master-lcore <ID> -l <ID> -n <CHANNELS > -w < PORT 3 PFA > -w <
PORT 4 PFA > --socket-mem=<MEM SIZE> --file-prefix=l3fwd -- -p <PORTMASK> --
config="(port,queue,lcore)[,(port,queue,lcore)]"
For example,
# l3fwd-atom-latest --master-lcore 2 -l 2,3 -n 3 -w 03:00.0 -w 04:00.0 --socket-mem=512 --
file-prefix=l3fwd -- -p 0x3 --config="(0,0,2),(1,0,3)"
Parameters setting:
th
--master-lcore 2:The 3
running l3fwd master process. Please note that the selected master core
needs to be one of CPU cores which are assigned for Tx and Rx
