It’s been fun four months of 2018 so far and I’m back to talk about Wireless VLANs. With 802.11ax around the corner (2019) I think we all can agree that “weird” connections although less likely have interference isn’t as mobile as a wireless LAN. Also, with 802.11ax the maximum theoretical throughput is 10Gbps! We’re going to need some serious backend infrastructure available to be able to support that type of bandwidth. So, let’s look at configuring a wireless VLANs for our mobile users!

Let’s start out 2018 with private VLANs, with PVLANs the network gets a little more privacy added to it. When we have privacy on the network we can seclude certain parts of it. Essentially, “you can go about your business – move along, move along”. Private VLANs allow us to segment networks within a single VLAN. So in this post we’ll go over the types of PVLANs as well as setup a network topology with private VLANs, Let’s get started! 
So what has changed in the past 20 years? Take for example the network equipment that was manufactured in 1997, how did you configure that equipment? I would imagine it involved a serial port, HyperTerminal and trusty command line. Was API even a thing back in 1997, was it common to have an API interface in network equipment like today? Why do we even need an API on the equipment in the first place? What changed?
