I think the problem was that it was too simple! Seriously! I must warn anyone reading this that I’ve worked with a Cisco CCIE while working on Hyper-V and previously with another senior Cisco guy while working on VMware ESX and neither of them could really get their heads around this stuff. How about a virtual machine how do you bind the virtual NIC of a virtual machine to a specific VLAN? It’s a similar process. Some software (HP NCU) allows you to create multiple virtual network cards to bind the server to multiple VLAN’s using one physical NIC.

Then on the server you need to use the network card driver or management software to specify which VLAN to bind the NIC to. That’s when all VLAN’s are available on that port.
The network administrators can create a “trunk” on a switch port.
The network administrators would assign the switch ports that will connect the server to a specific VLAN. How do you tell a physical server that it is on a VLAN? That is used by administrators for configuring firewall rules, switches and servers. We open up what ports we need to between VLAN’s and to/from the Internet.Įach VLAN has an ID. Each VLAN is firewalled from every other VLAN. That last one is why we have multiple VLAN’s at work. The want to separate network devices using firewalls. They need to be creative with IP address ranges. Control broadcasts because they can become noisy. Network administrators use VLAN’s for a bunch of reasons: it is a single subnet and broadcasts cannot be transmitted beyond its boundaries without some sort of forwarder to convert the broadcast into a unicast. How would you do it if they were physical machines? The network administrators would set up a Virtual Local Area Network or VLAN. How do you run multiple virtual machines on different subnets? Forget for for just a moment that these are virtual machines.
