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.

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...

The migration to cloud-based communication solutions offers significant advantages. However, organizations can maintain a measured pace and seamlessly integrate existing on-premises PBX or PSTN infrastructure with Webex Calling through Local Gateway Deployment. This approach allows you to capitalize on your previous investments while enjoying the benefits of cloud calling.

As you saw in a previous post, DHCP Hacking Made Easy, poorly configured networks can serve as an attack vector for “The Attacker”. In this entry, we continue this exploration with another dead simple attack on the network, ARP spoofing. ARP is the protocol responsible for informing hosts within a given LAN, which IP addresses belong to which MAC addresses. What happens when we provide bad...

Using DNA Center (Catalyst Center) LAN Automation to make your life easier.

I am currently deploying an SD-Access fabric using Cisco's DNA Center, now rebranded as Catalyst Center. As part of this project we used the LAN automation process to build the network to all of the access switches. We had about 15 different switches in 15 different IDFs so using this process made quick work of...

Understanding Switch Stacking

Switch stacking is a technology which will allow multiple switches to become a single logical switch. Which will allow you to manage them as a single switch. Cisco has Stackwise. Stackwise architecture allows stacking up to eight switches. Other Vendors has their own stacking technology which is similar. In this discussion, we are only going to go through adding a...
