Starting with Firepower 7.2, Cisco announced the ability to manage these firewalls using a Cisco hosted Cloud-Delivered Firewall Management Center (cdFMC). I recently had a project setting up cdFMC for the first time so I figure I would go over what I learned and show how to access cdFMC, how to import policies, and join your first Firepower firewall.

This post is the second post in a three-part series on QoS.  If you haven't read the first blog post, I highly recommend reading the first part here.

I just completed a Quality of Service, or QoS, assessment for a customer. While I was writing the assessment, I decided to brush up on my knowledge of QoS best practice to better serve the customer. While it's still fresh in my brain I figure I will...

Network documentation is arguably both the most important and most over looked tasked a network administrator does. A good network diagram is invaluable for understanding how a network is working, for troubleshooting when its not working, and a great source of information when onboarding new employees to the network team or, more important to me, getting vendors and partners up to speed on how...

Cisco SD-WAN (formally Viptela) is quickly becoming the go to WAN solution for Cisco customers. As companies are looking to replace their aging DMVPN solution, Cisco SD-WAN has become the logical choice.

This is great for Catalyst owners who do...

I am currently finishing a project where I am designing a custom Quality of Service policy for a customer's suite of business critical applications. The customer uses MPLS as their WAN and the bandwidth for the MPLS is different depending on the site; Datacenters have more bandwidth, branches have decent bandwidth, and small kiosks only have a few megabits of bandwidth. The customer noticed that...

With the explosion of wireless technology we have experienced in the last few years, wireless networks are being asked to handled more and more demanding traffic. Between laptops, cell phones, and wireless IoT devices, the importance of having your wireless infrastructure optimized has never been greater.

We have all been there; sitting down to dinner on a Sunday night, when you get an alert that one of your branches has gone offline. You politely excuse yourself from the table, open your laptop and start troubleshooting. The problem, you can’t access any of the gear to troubleshoot the issue, and the gear you can access isn’t providing any answers to why the site went down. Now you are faced with...

In the modern networking world routing protocols fall into two distinct camps, Link-state and Distance Vector. Being a network consultant I often have customers asking me which routing protocol is better so I figure I would create a post comparing the different routing protocols.
