Policy Based Routing on a Cisco Switch

While policy based routing is available on a great many Cisco switches, you will need the right firmware that supports it.  For my home lab, a 3560X is my main switch, it requires 15.1-15.3 to work, currently 15.2 has MD releases, which is what I used.  A quick show sdm prefer will output the features you have available, ensure ip routing is enabled as well.

Lastly, as far as creating an access list for policy based routing, ensure you deny your internal networks in the ACL prior to implementation or a lot of things won't work.

access-list 100 deny   ip
access-list 100 permit ip any

This ACL will allow you to policy route all traffic that is external to a next hop.
