Would it help if I mentioned that your untagged traffic is probably
getting tagged somewhere, almost certainly with a PVID of 1, which is
the "default VLAN"?

It sounds to me like your switches have decided that traffic in the
default VLAN needs to be transported to other segments of the default
VLAN, and this is what trunk ports are for...

The VLAN koan:

   Goso said:  ``When a packet goes out of its egress to the edge of
   the abyss, its header and its payload all pass through, but why can't
   the VLAN tag also pass?''
                                                                                
   Kevin's comment: If anyone can open one eye at this point and say a
   word of layer-2 bridging, he or she is qualified to discuss the
   intricacies of ``one-armed routers'', and, not only that, he or she
   can save all sentient beings under them from broadcast storms caused by
   Windoze boxen.  But if he or she cannot say such a word of true IEEE 802.1Q
   VLANs, he or she should turn back to their tag.
                                                                                
        If the packet is transmitted, it will fall into the ether;
        If it remains in the queue, it will exceed its TTL,
        That little VLAN tag
        Is a very strange thing.
