Subject: DSA Switch: query: Switch configuration, data plane doesn't work
whereas control plane works
Hi Team,
This could be basic question related to DSA, if possible please help
to share your feedback,. Thanks.
External CPU eth1 ---RGMII---- Switch Port 0 (cpu port)
Switch Port 1 (lan1) --- DHCP client
I am using marvell 88E6390 evaluation board, modified the device tree
to support MDIO control over USB.
The switch control plane works, we are unable to dump registers and
see port status.
The kernel version on board with external cpu is 6.1
I have connected a dhcp client to port 1 of the switch and the
discover packet is not reaching the cpu port (port 0) and external cpu
interface eth1.
Using the bridge without vlan to configure, able to see the client
device mac addr in bridge fdb show
with vlan id as 4095.
tcpdump on external cpu port eth1 and bridge br0 to listen for
incoming packets from the client . No discover packets are being
received on those interfaces.
Could you please let us know if any configuration is being missed for
switch data plane to work ? Thanks.
The below are the commands used to configure the bridge:
ip link set eth1 up
ip link set lan1 up
ip link set lan2 up
ip link set lan3 up
ip link set lan4 up
ip link set lan5 up
ip link set lan6 up
ip link set lan7 up
ip link set lan8 up
ip link add br0 type bridge
ip link set br0 up
ip link set lan1 master br0
ip link set lan2 master br0
ip link set lan3 master br0
ip link set lan4 master br0
ip link set lan5 master br0
ip link set lan6 master br0
ip link set lan7 master br0
ip link set lan8 master br0
