LX2160a DPSW not working with IPv6

Hello,

I would like to use DPSW together with IPv6. No matter what I do, IPv6 is not working. IPv4 is okay.

I tried several MC-Versions (1.24.0, 1.28.0, 1.29.1) together with linux kernel 5.4 and LSDK-20.04. No difference.

With ethtool I can see an increasing number of "rx discard frame" on the ingress port of the switch. It seems, that IPv6-multicast-packets (ethernet mac 33:33:xx:xx:xx:xx) are discarded.

IPv4-Multicast-packets are working.

A minimal setup script is attached.

  • works: ping 192.168.45.2
  • not working: ping fdc2:10:20::2

Do I miss something or are there any known issues?

IPv6 itself works, if i directly connect 2 dpni or one dpni with dpmac.
