I'm in the process of working on a new switch configuration. Basically what we have are 2 L3 switches that will have multiple VLANs and 802.1Q enabled. If devices are plugged into the L3 switch things work fine.
The question/problem I have is that these L3 switches are connected to a stack of L2 Cisco switches via the gig uplink ports. All L2 switches are basically base config'd, no VLANs.
My thought process is if I have the production network (which all the L2 switches connect to), I'm going to have to configure all the L2 switches to be on the same VLan as it is configured on the L3 switch.
I've done some testing and right now when I plug into the L2 switch connected by the gig backbone (no config done on backbone) I can't talk to anything on the L3 switch.
Is there something I'm missing here or what is my next step in the right direction?
