Thanks to Cisco’s push to deploy more Thousand Eyes agents, the Catalyst team has given us an easy button for deploying agents to the Catalyst 9300 and 9400 switches using Catalyst Center, formally DNA Center. The agent is deployed as a docker container using the App-hosing framework built natively into the 9300 and 9400 series platforms. Catalyst Center streamlines the deployment of the...

OSPF is mostly used between a Core switch and downstream OSPF enabled devices like distribution switches, firewalls, etc. If the downstream device is connected via link aggregation to a Nexus vPC pair and vPC peer-gateway is configured, you will encounter OSPF adjacency flaps. This will not be noticed unless the OSPF adjacencies are monitored or debugged, so most engineers are not even aware that...

My latest project has been a switch refresh and a deployment of a Catalyst Center with Assurance only for a customer across all of their sites. Now the task I had at hand was how can I use Catalyst Center to automate as much configuration on the switches as possible. Because we were only licensed for Assurance we did not have access to use any of the SD-Access fabric automation that Catalyst...

It’s been a long time coming. I’ve been searching for a reason to do it…and I finally did it! I solved my first real world networking problem using automation!

I know, I know. The many of you out there who do this every day all day don’t care, but for me, someone who is an expert network engineer and a n008 at python (programming in general), I’ve been waiting for the day that it made sense to...

You know how to whistle, don’t you? Just put your lips together and blow. Well installing WSL is nearly as easy and can up your efficiency and expand your toolset.

Creating device templates in Cisco vManage is a crucial skill for network administrators looking to streamline and automate the management of their Cisco SD-WAN infrastructure. By using device templates, you can standardize configurations across multiple devices, ensuring consistency and reducing the likelihood of configuration errors.

Border Gateway Protocol (BGP) stands as a foundational protocol in the realm of internet routing, facilitating the exchange of routing information between different autonomous systems (AS). In this technical blog, we'll delve into BGP and explore the significance of the ip as-path access-list command on Cisco devices.

Passwords, or In-The-Past Words?

Are passwords a thing of the past? Well to be honest, no not yet they aren’t, but there seems to be a widespread initiative to cram them into a time capsule, move into the future, and forget about them altogether. From post-it notes to password managers, to any of the other tools or tricks that people use to remember them, passwords are renowned for being a weak...

Hey Team! Today we will be looking at a quick “How-To” on how to go about Editing/Deleting NAT rules and Access Control List entries, inside of Cisco Defense Orchestrator for Firepower Management Center. Let’s get to it!

In my seemingly endless quest for the CCIE, I have learned about two decently powerful tools that together make an incredibly powerful and custom solution for modern DevOps/DevNet network; Embedded Event Manager (EEM) scripting, and Guestshell in IOS-XE devices. EEM scripting is far from new in the world of Cisco networks, it is a custom event driven scripting tool that executes custom...
