Hi Guys,

I am trying to run the l3fwd dpdk app on my machine.

I am getting the following error, can someone help me, Thanks.

Hi Pragash,

How many ports are assigned to dpdk?
Why is there only 1 port in the portmask (-p 0x1)?

Dpdk would typically use pair(s) of ports.
First port(0x1) in the portmask(0x3) is usually ingress traffic and the second port(0x2) of the pair is the egress traffic.
Try with -p 0x3 portmask but make sure you have at least 2 ports already assigned for use with a dpdk app.
If you have more than 2 ports adjust the portmask hex number to reflect the situation.

Not showing "Active" status is perfectly normal.

The problem here is that you will probably need to supply extra parameters.
This is from your previous posts:

pragash at revvit<http://dpdk.org/ml/listinfo/users>:~/dpdk-stable-17.05.2/examples/l3fwd/build$ ./l3fwd -l 0-4 --no-huge -- -p 0x1

Try changing to:

pragash at revvit<http://dpdk.org/ml/listinfo/users>:~/dpdk-stable-17.05.2/examples/l3fwd/build$ ./l3fwd -l 1-4(core 0 is usually master lcore) --no-huge -- -p 0x3 -L(optional) -config="(0,0,1),(1,0,2)" --parse-type



This worked for me. You can check the docs here http://dpdk.org/doc/guides/sample_app_ug/l3_forward.html for all options.


If you don't specify the "config" option the app won't even start returning the "check port config" error. You must also supply the "-parse-type" cmd parameter otherwise app complaints and fails to start with the following error "port 0 cannot parse packet type, please add -parse-type"

If your nb_ports = 0  shows that you haven't bind/provided any ports to dpdk.

Just verify that the ports that you want to use with dpdk (igb_uio) are available on the machine.
This means that they are not used for anything else but dpdk.

Before you attempt to bind any ports to igb_uio, from the terminal check what ports are available on the machine using nmcli d or any other utility.
Load the igb_uio kernel module using the dpdk_setup  script in dpdk/usertools
Then use the dpdk_dev_bind or dpdk_setup  script to bind the selected ports to igb_uio.
Verify that the ports are using the igb_uio with the dpdk_setup  script. There is an option there for that.

If you are using 2 ports (-p 0x3), use 2 lcores (-c 0xE) core 2 and core 3 in this case.
Complete the cmd like this:
pragash@revvit:~/dpdk-stable-17.05.2/examples/l3fwd/build$<mailto:pragash@revvit:~/dpdk-stable-17.05.2/examples/l3fwd/build$> ./l3fwd -c 0xE --no-huge -- -p 0x03 -L --config="(0,0,1),(1,0,2)" --parse-ptype

If you want to use more lcores you must then change the -config option to reflect the situation in terms of (port,queue,lcore)

Please use only 2 ports with 1RX queue and 1 TX queue each to get l3fwd running. Try with these 2 below.
0000:02:00.0 'Ethernet Controller XL710 for 40GbE QSFP+ 1583' drv=igb_uio unused=vfio-pci
0000:02:00.1 'Ethernet Controller XL710 for 40GbE QSFP+ 1583' drv=igb_uio unused=vfio-pci

You can use more ports/queues but then you'll have to change the -config option depending on how many cores do you want to use.

The cmd that I've provided in my previous post is specifically for 2 ports with 1RX and TX queue each and 2 cores.

I suggest that you restart your machine, if possible, to unbind all ports from igb_uio and start from scratch.
Otherwise use the dpdk-seup.py script to do the clean-up.

Unfortunately I don't have XL710 NIC available to test.

Off the top of my head:

-          Is this an issue only with the l3fwd app?

-          Did you try to run testpmd, skeleton or l2fwd?

-          Is the card working properly with the kernel driver?

-          Did you try previous version of dpdk?
