So we are about to install an application that require pieces of the application on different vlans for security purposes. So the web server sits on one vlan, application server in another vlan, and the Database server in another vlan. We restrict traffic via source ip, destination ip, and port between vlans. I have 3 switches configured each one configured for their respective vlan. The problem is the guys in charge of VM Hosts don't have enough physical ports to map a port to each one of these switches. I started looking into virtual switch in vmware and the cisco virtual switch. Would implementing a vswitch, allow me to have 3 different vlans, without the need to map a physical NIC port to each one of these vlans? I feel like I'm missing something, and there has to be an easier way. I never played with a vswitch, and am looking for some insight for this scenario. Thanks.
