Hi,
I’m trying a simple setup with a DPSW on CEX7 board.
I have a network cable connected to a host PC via MAC17.
On boot, I perform the following:
ifconfig eth0 192.168.0.100 netmask 255.255.255.0
After this I have ping to my host.
Now I want to create a switch as follows:
DPNI <–> DPSW <–> DPMAC
So first I destroy the default dpni.0 connected to dpmac.17:
echo dpni.0 > /sys/bus/fsl-mc/drivers/fsl_dpaa2_eth/unbind
restool dpni destroy dpni.0
And then I create a new one:
ls-addni -n
Finally I create a switch with two ports:
ls-addsw -i=2 dpmac.17 dpni.0
And setup the IP for the DPNI
ifconfig eth0 192.168.0.100 netmask 255.255.255.0
However, there is no ping and the link seems to be down.
root@localhost:~# restool dpni info dpni.0
dpni version: 7.17
dpni id: 0
plugged state: plugged
endpoint state: 0
endpoint: dpsw.0.1, link is down
link status: 0 - down
mac address: 22:15:87:c8:a7:35
...
root@localhost:~# restool dpmac info dpmac.17
dpmac version: 4.7
dpmac object id/portal id: 17
plugged state: plugged
endpoint state: 0
endpoint: dpsw.0.0, link is down
DPMAC link type: DPMAC_LINK_TYPE_PHY
DPMAC ethernet interface: DPMAC_ETH_IF_RGMII
MAC address: d0:63:b4:03:b6:e7
...
A similar sequence has worked for me in the past on NXP LX2 RDB, however I no longer have access to that board so I can’t compare the results.
Any ideas how to make this work?
Thanks
Dmitri
are you setting the link up after you re-create the network interface? You would need to manually use ip link set eth0 or whatever interface is created after bringing up the DPSW interface.
Yes, as I described above I perform ifconfig eth0 ... to set up the Iink, I believe it has the same functionality as ip link ....
Again, same sequence worked for me on NXP RDB.
no that ifconfig command only adds the ip address to the interface. The interface also needs to be brought up which can be done by adding up to the options. However I do recommend you learn to use the ip command set, ifconfig has been deprecated in favor of iproute2 for over a decade now.
I’ve rerun the test with ip commands.
Destroy default dpni.0
echo dpni.0 > /sys/bus/fsl-mc/drivers/fsl_dpaa2_eth/unbind
restool dpni destroy dpni.0
Create new DPNI
ls-addni -n
Create switch
ls-addsw -i=2 dpmac.17 dpni.0
Add IP address and enable interfaces
ip addr add 192.168.0.100/24 dev eth0
ip link set eth1 up
ip link set eth2 up
ip link set eth0 up
Still, there is no ping to host.
Is there something else I’m missing?
See “ip addr show” and “restool dpsw info dpsw.0” commands output, all interfaces are shown as “up”:

Sorry this just took me a bit to get around to. With recent kernels and changes to the driver you need to bind the interface to a bridge for dpaa2 switch drivers to work. Please see step 4 of this guide, NXP
With this setup I am seeing a fully switched interface on the HoneyComb when running tcpdump on the br0 interface I see no traffic between other devices connected to the complex but IP packets going to and coming from the br0 ip address as visible and have connectivity to the fully network.
Hi, sorry for the late response.
I now have it working with the instructions you linked, thanks!
Detailing the sequence here for future reference:
Destroy default dpni.0
echo dpni.0 > /sys/bus/fsl-mc/drivers/fsl_dpaa2_eth/unbind
restool dpni destroy dpni.0
Create new DPNI
ls-addni -n
Create switch
ls-addsw -i=2 dpmac.17 dpni.0
Configure the switch interfaces and add them to a bridge
ip link set dev eth1 down
ip link set dev eth1 address 00:00:00:00:00:02
ip link set dev eth1 up
ip link set dev eth2 down
ip link set dev eth2 address 00:00:00:00:00:03
ip link set dev eth2 up
ip link add name br0 type bridge
ip link set dev br0 up
ip link set dev eth1 master br0
ip link set dev eth2 master br0
Add IP address and enable interface
ip addr add 192.168.0.100/24 dev eth0
ip link set eth0 up
Ping host
ping 192.168.0.1
