LS1043A L2FWD TEST QUESTION

[jack_huang1]

In the process of using DPDK for performance testing, we can observe the normal packet receiving and receiving through L2FWD, but the PC connected through the physical port catches the packet, but there is no packet, I would like to ask, what is the reason?

The L2FWD observations are as follows：

Port statistics ====================================
Statistics for port 0 ------------------------------
Packets sent:                        0
Packets received:                    0
Packets dropped:                     0
Statistics for port 1 ------------------------------
Packets sent:                        0
Packets received:                    0
Packets dropped:                     0
Statistics for port 2 ------------------------------
Packets sent:                       16
Packets received:                   46
Packets dropped:                     0
Statistics for port 3 ------------------------------
Packets sent:                       46
Packets received:                   16
Packets dropped:                     0
Aggregate statistics ===============================
Total packets sent:                 62
Total packets received:             62
Total packets dropped:               0

The specific operation of the test is as follows:

-  script configuration large page（512）：
/usr/local/share/dpdk/usertools/dpdk-setup.sh

- fmc configuration：
export PATH=$PATH:/usr/local/bin
export DPAA_NUM_RX_QUEUES=1
/usr/local/bin/fmc -x
/usr/local/bin/fmc -c /usr/local/dpdk/dpaa/usdpaa_config_ls1043.xml -p /usr/local/dpdk/dpaa/usdpaa_policy_hash_ipv4_1queue.xml  -a

- l2fwd command ：
l2fwd -c 0xf -n 1 -- -p 0xf -q 1 -T 0

Please check. Thank you.

Hello 克祥 黄,

I didn't find obvious problem in your description, please check the package catching tool on the PC.

In addition, no need to run "/usr/local/share/dpdk/usertools/dpdk-setup.sh"

Please refer to the following procedure which I got from the testing team.

#cat /proc/cmdline

# umount -l /mnt/hugepages

# mkdir -p /mnt/hugepages
