Cable modem cisco Layer 3 switch

Hello is there anyway to hook up my modem directly into my cisco layer 3 switch and use it as a router? My cable modem is not static by the way

The articles below suggest (1) some Cisco switches can work as routers and some cannot and (2) using a router for routing tasks and a switch for switching tasks.

Is there an advantage to be gained for you to use a switch in place of a router?  

I use a Cisco RV042G router from my cable modem and it is as fast or faster than the cable modem so it doesn't present any limitation to me.

I just have an old router and would like to use my 3560g switch partly to experiment part to use because it's probably better than my old link sys router
A Cisco 3560g should work as a router, but it will probably take more configuration that a router designed for the purpose. I assume the "g" means it is gigabit like my RV042g (which is also gigabit). Yes, almost for certain, it will be faster and probably more reliable than an old router. I have replaced may of those since I first had broadband in 1999.

Can you use your Cisco 3560g as a router? Yes.  As to configuration to do it, you would need a Cisco switch configuration expert (not I).

The switch configuration is a little more involved than a Cisco router, but setting up a Layer3 siwtch to be your router is not that difficult.

I used an old Catalyst G-L3 model that used BVI interfaces instead of VLANs, it worked great.
