We have recently come across few production networks, where distance between two APs or APs and a client stations was much closer than I was comfortable with. Natural reaction was to suggest moving radios at least few metres apart. But why exactly? What happens when two or more transmitting radios are too close to one another?…

Hey! Welcome to our very first blog on our journey to learn some coding. I decided it was finally time to stop burying my head in the sand & to make a start with taking a dive into the world of coding. This is my very first time trying to properly understand what is…

In our previous blog (please start there), we were typing in all the site IDs, WLAN IDs, API authentication tokens & Mist API HTTPS URL manually. It’s no fun, right? Since we’re likely to interact with Mist API using one Mist account, we’ll probably use one API key globally. Additionally, we’ll probably interact with specific organisations,…

Let’s face the truth. We can’t avoid dev stuff in WiFi forever! REST API, Python, JSON, Ansible and whatever else is needed – here we come! It’s time. This is day 1 of our studies! The mission for today? Actually we have a few 🙂 Extreeeemely complicated, we know 😉 Let’s assume everyone knows…

Hey! I have just recently attended the Ekahau & Open Reality WiFi Design Day 2019 at the ICC in Birmingham and thought I would do a blog post to summarise my experience and thoughts. This was my 3rd year in a row attending from the 1st one back in 2017 at the Churchill War…

Hey! Welcome to another one of our Cisco C9800 configuration blogs! This time we will be covering Local Web Authentication (LWA), where guest sessions are managed by the WLC itself. We can authenticate against RADIUS, TACACS, LDAP or local WLC Guest Users database. In this guide we will use local WLC Guest Users. As…

Upgrading Cisco Catalyst 9800 software is easy and sleek. You could use all standards protocols to put a new image on the controller: FTP, TFTP, SFTP or HTTPS. Here are the steps: Installation and reload is extremely fast and takes just a minute or two (at least for the CL version). Enjoy!

Hey! And welcome to another C9800 blog 🙂 Recently, Matt has blogged about Redundancy configuration using GUI and covered HA/SSO operation here. Today, I wanted to do a deeper dive into the topic. Enjoy! Lab Environment: In my lab, both C9800-CL VMs will sit on a single ESXi box. In the real world, they would…

Hey! Welcome to another one of our blogs on configuring the new Cisco Catalyst 9800 WLC. This time we are going to take you through configuring 2 x C9800-CLs for redundancy HA SSO.  First here is an overview of my home lab setup: I currently have 2 x ESXi servers and a C9800CL on…

Finding C9800 stuff hot and interesting? You’re not alone out there! 🙂 After initial C9800 configuration (see this blog) and registering your first AP (our AireOS AP Join Blog is still applicable here) you’re pretty much ready to go! There are just some pre-reqs to consider before we can associate with our first C9800 BSSID. Pre-reqs Note:…
