Hi Ilias Thanks for removing the CPU port. That helps a lot moving forward.

Is this something you can work around? Is there a TCAM you can program to detect IGMP and pass the packets to the CPU? Without receiving IGMP, multicast is pretty broken. If i understand right, a multicast listener running on the CPU should work, since you can add an MDB to receive multicast traffic from the two ports. Multicast traffic sent from the CPU also works. What does not work is IGMP snooping of traffic between the two switch ports. You have no access to the IGMP frames, so cannot snoop. So unless you can work around that with a TCAM, i think you just have to blindly pass all multicast between the two ports. > Setting on/off and IFF_MULTICAST (on eth0/eth1/br0) will affect registered > multicast masks programmed in the switch(for port1, port2, cpu port > respectively). > This muct occur before adding VLANs on the interfaces.

You should be able to get the stack to tell you about all the configured VLANs, so you can re-program the switch. > - NFS: > The only way for NFS to work is by chrooting to a minimal environment when > switch configuration that will affect connectivity is needed. You might want to look at the commit history for DSA. Florian added a patch which makes NFS root work with DSA. It might give you clues as to what you need to add to make it just work. Andrew
