Enabling routing on a layer 3 switch.

Enabling routing on a layer 3 switch.

It combines switching and routing

Loaded question. This depends on the Cisco switch and it's a very technically detailed answer - unique to every switch model. The short answer is that switches that are "modular" allow you to have routing functionality inside one or more "modules" or "cards" of the switch. Some switches allow routing to occur on each "line card", other solution allow a switch to share a single "card" to do all the routing for the entire switch. Routing and switching can be configured via a single terminal interface session - known as "native", whereas some switches separate the routing terminal and switching terminal - known as "hybrid". If that isn't enough info, go to cisco.com and use their search engine to find the "installation guides" of your model.
