ACLs on Switch or Router?

go to www.cisco.com and type ACL in the search box.
You will find usefull info about ACL and the diferent CISCO products. You will be able to select the product more apropiated to your needs.
About applying the ACL to a switch or to a router the answer will need to look at your network diagram, but remember that is better to apply the ACL to the first device in the network that gives access to it.

Access Control Lists can only be setup in your router.

A switch is not able to filter IP packets, only ethernet packets. So if you want to filter by MAC addresses you can use your switch. This is not a very good idea because its is very hard to maintain.

There are some models of Cisco ethernet switches that have a router built in. These are known as Layer 3 switches. You are actually configuring a router most of the time.

In a hosting network, it is most likely that you would use a router for filtering since this will give you greatest control over the filters. Its is also the device that would gateway to the Internet so this is usually the best place to apply filtering.

Hope this helps.
