Hi.

More details are needed. Could you provide the following from the 2960:

show ver

show run

show log

show interface status

It sounds like you have Spanning-Tree blocking something since "no span-tree vlan 1" removes your issue. However, that disables Spanning Tree, which is *not* a good thing in a network.

Any error message in the 3Com switch?

HTH.
