We are a business of about 50 employees. We've always just used cheap dumb Netgear switches. We have a 16 port and a 24 port switch hanging off an RV082 router. There are then connections from these switches to our production PCs. We also have one line that goes out into an adjoining building and connects to a switch out there, which in turn provides network connectivity to a bunch of PCs out there. That's just to give you an idea of where we're at now.
Now, we're installing new WIFI and need to have guest access capabilities so we're looking at getting a layer 3 core switch so we can use VLANs. My question is in regards to sizing the core switch. Is it best to get as many ports as possible to have our PCs connected directly to this core switch or is it OK to get a smaller switch with fewer ports and hang our dumb switches off of that and have that be a distribution switch. Do we lose anything by doing this? I'm trying to figure out whether I need a 52 port switch or if I can get a smaller one and expand the ports by hanging our dumb switches off that. If I haven't given enough info, please let me know and I'll fill in the blanks.
