CISCO 3560 SWITCH - VLANS - SECURING VLANS

I have a WS-C3560X-24P-S 24 port switch that I have VLANS created on -

this switch will be put into a multi-tenant building / each port equates to a separate office.

I have all of the interface stuff ready to go but would like to secure each VLAN from each other.

I am guessing that I need some sort of access-list to accomplish that - Is there any other way?

It allows you to restrict traffic between ports (VLANs) without requiring you to create a separate IP addressing scheme for each VLAN.

Basically, there are 3 types of ports in a private VLAN environment.

Isolated - Can only communicate with promiscuous ports
Community - Can only communicate with ports in the same community and promiscuous ports (you can have multiple communities).

Promiscuous -WS-C3560X-24P-L Can communicate with all ports.
