VLans and Broadcasts

[eicke]

Hi Folks,
I have 3 sub-nets here at my job,
192.168.1.x
192.168.2.x
192.168.3.x
In the past each sub-net were connected in one switch
I have a Switch 3300TM and I created 3 Vlans.And connect the sub nets, now the broadcasts from, for example, 192.168.1 sub-net are send to anothers sub-nets. I believe that is something wrong.
Could anybody help me?
Thanks and Regards.
Eicke.

What do you mean by '...and connect the subnets'

Is there a router or layer-3 switch involved that is routing between the 3 subnets or are they supposed to be completely separate?

Can you give us some idea of how you set the thing up? (bridge, vlan, addport etc)
