We installed accidentally a 2950 switch to an exisiting 4000 series switch. Suddenly our network team noticed span tree errors and looping. It seems as though the ports that were connected defaulted to trunking. Just wonderring if this is the norm for cisco switches and what we could have done to avoid that.

do you have vlan??  by default all port function as regular not trunk unless you configure it. or it could be the other way around.  4000 port could be set as trunk and 2950 set as standard.
