We are redoing a portion of our building.
We use a 192.168.100.x range for the building.
We have an outside connection for a client system that we use, it uses 10.0.24.x. When that connection comes in, we plug it into a different Cisco switch than the ones on the 192 range. The consultant asked why don't I just plug them all into the same switch??
Can I do that?? Forgive my ignorance, but I figured everything needed to be on the same subnet on the same switch.
You can configure on the switch ports 1-12 for vlan x and ports 13-24 for vlan y. Of course if you have a 24 port switch that supports VLANing. Without a layer 3 device the two vlan's/subnets will not talk to each other. Some intsances it is best practices to seperate inside from outside traffic on seperate switches. Hope this helps.
