I have 3 switches, (1)3550 and (2) 2960's, each one is 48 ports. I'm using the 3550's port F0/1 for routing, all the other ports have a VLAN tied to them.
3550 = swA
2960 = swB
2960 = swC
swA = (4) VLANs (Servers, Printers, Office, IT)
swB = (2) VLANs (Sales & Marketing)
swC = (3) VLANs (WIFI, Pub Access, Service)
swA gi0/2 to swB gi0/1
swB gi0/2 to swC gi0/1
Right now I have all VLANs being trunked acrossed all trunk ports
For trunking purposes on swA, do I need to trunk its VLANs to the other switches? And the same with swB's VLANs being trunked to swC.
I'm thinking that I dont have to because if a VLAN needs access to another VLAN it is going to the routing for where to go. Like router on a stick. But if I have printers on swC I would then need a trunk for it to let the switch know where the other port is located.
This is what I'm thinking it should be.
swA gi0/2 to swB gi0/1 (Sales, Marketing, WIFI, Pub Access, Service)
swB gi0/2 to swC gi0/1 (WIFI, Pub Access, Service)
