  1. Hi Michael,

    Glad to hear you like it :slight_smile: Security will depend on which access layer we are dealing with.

You probably don’t want to use any firewalls there…not because there are no risks but it will be very expensive.

    You can configure your switches for some of the security risks on the access layer here:

    - Port Security: against MAC spoofing / setting a limit to number of MAC addresses per port.
    - DHCP Snooping: so nobody can

    There are layer 3 switches in the chart but this is because those are the “lower end models” that Cisco has to offer. They can run as layer 2 switches and not utilize the layer 3 functionality. As switches have gotten more powerful layer 3 functionality has been easier to put into a switch. A big consideration of what switches you might use in a network is the size of said network. A tiny network might only need 296
