When you want more speed all you need is EtherChannel, EtherChannel can be configured as a layer three logical interface instead of just sitting at layer two. This is very helpful if we are running layer three down to the access layer switches, instead of at the distribution layer. You also could see this in a collapsed core design, we also don’t have to worry too much about STP when we configure EtherChannel’s. The only requirements to use layer three EtherChannels is your switch need is support layer three “routed” interfaces, so with that let’s get started!

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!
