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 l2fwd program
# l2fwd-atom-latest --master-lcore <ID> -c < COREMASK > -n <CHANNELS > -w < PORT 3
PFA > -w < PORT 4 PFA > --socket-mem=<MEM SIZE> --file-prefix=l2fwd -- -p <PORTMASK>
Considering the command above is relatively complicate we use a dual Cpu sockets platform
as an example,
# l2fwd-atom-latest --master-lcore 2 -c 0000000c -n 3 -w 03:00.0 -w 04:00.0 --socket-
mem=512 --file-prefix=l2fwd -- -p 0x3
Parameters setting:
th
--master-lcore 2:The 3
running l2fwd master process. Please note that the selected master core
