3com (c16475) + cisco 2950, 3com does not pass cisco traffic?
There is such a piece of iron 3com (c16475), behind it is a router with dhcp. In 3com included cisco catalyst 2950. On cisco port in trunk, other access ports, all ports in vlan 1. The internal network works, that is between the computers connected to cisco a network is. Actually the problem is, I don’t see everything for 3com anymore, there are several more segments of the same network. Previously, instead of a cisco table, here is such a surecom ep piece of iron - 816vx, an ordinary unmanaged switch. What could be the problem?

1 port in switchport mode access, because since it was unmanaged, no trunk was configured in 3COM.
Or start a trunk on this port in 3COM.
