Using Ansible to deploy Juniper configurations

Ansible_plus_Juniper
Automation is a growing technology in enterprise IT departments.  The ability to automate hundreds of steps for developing, building, deploying, and scaling applications and servers is a huge win for many of our fellow engineers.  Both DevOps and SysOps are loving the new power that it brings.  But, what about NetOps?  Is there any love there?  Well, there is now, thanks to a few developers at Juniper Networks, Ansible, and others. In this video, I will show you how to deploy a configuration to Junos devices using Ansible.  The configuration is just a simple single-line configuration, but I...

Using Python for Juniper on a Mac

stock_175px-juniper-networks
Juniper Networks has developed a python library to manage their devices.  The library is called "junos-eznc" hosted at GitHub.  This library is meant to be able to handle commands programmatically that you would usually do at a CLI.  In order to use it, you will need to also install "ncclient" which implements NETCONF in python.  The easiest way to install is to use PIP. MacPro:~ aaronpaxson$  sudo pip install ncclient MacPro:~ aaronpaxson$  sudo pip install junos-eznc If you receive an error regarding "error: 'cc' failed with exit status 1", this is because you don't have the C compiler in...

Cisco OnePK Topology

OnePK-AllInOne-Topology
In my last post, I showed you how to get Cisco's free OnePK all-in-one VM to run inside Parallels for your testing.  I needed an easy-to-read topology map for quick reference as I do my tests.  The topology map that Cisco put in their documentation is less than ideal.  Below is my diagram.  Some quick notes: The brown ethernet segment (10.10.10.0/24) is the VM Guest segment.  This allows you to access the routers from within the VM using the static IP's assigned to the interfaces. The red ethernet segment (ETH1 / DHCP) is a DHCP-based segment for the VM Host.  This allow you to access th...

Cisco OnePK VM in Parallels

cisco-onepk-logo
Over the last couple of weeks, I've been bit by the "Automation Bug".  I want to automate everything.  Why?  Well, there are two reasons why I want to automate everything I can: Remove tedious, mundane, and repetitive tasks.  If I can do the same task over and over again, not only do I save time, but I remove any human errors from the equation. Abstract the complexities of the tasks at hand.  This is very useful when delegating the tasks to personnel who may not fully understand or know the intricacies of the steps. This week, I've started to learn about Cisco's OnePK software develop...

Facebook offering network switches?

Cat5 Cable
Well, maybe not Facebook, itself, but with the community it has spawned. The news is sparking again with SDN buzz, as Facebook’s OCP project (Open Compute Project) has signed up a network hardware manufacturer to build and sell the ‘Wedge’, as Facebook calls it. The Wedge started as a design idea built on an open-source community to build and weave different pieces of hardware to accomplish a task. It could be a web server, or, as you may have guessed, a network switch, with SDN being a core-concept in it’s use. As such, specific software-defined interfaces are built into the design. On ...

Reason For Outage Report

Key Resource
When working in groups, sometimes you need to update management as to large problems.  Emails work, but usually different people get different pieces of information, and there is no consistency.  Because of this, an RFO Report (Reason For Outage) is used to identify the problem that happened, that impact it had, and the root cause of it, so it doesn't happen again. Using this report, you can send it out to anyone that needs it.  Depending on the person reading it, all the information they need should be included.  If not, you are welcome to modify it to your needs. If you are a large bus...

Blogger vs Influencer

Influencer
For a few years now, when I tell people that I blog I'm usually asked 2 important questions: How can I start blogging? How can I make money blogging? The first question is easy.  Go to wordpress.com, create an account, and start writing.  That's all blogging is, really.  The second question was best answered by Tom Hollingsworth (@networkingnerd): How to make millions blogging? 1). Become a millionare 2). Start blogging So, what does that have to do with being an influencer?  Well, an influencer is someone that people trust in order to hear what they have to say about certain produc...

Starting Juniper Certs? There’s an app for that!

Junos-Genius-Icon
For those starting on your Juniper journey into certifications, Juniper Networks has created a fantastic app for your Apple Devices to help you prepare for your entry-level exams.  But, you droid users out there aren't left out.  Called "JUNOS GENIUS", this app helps you determine if you are ready for entry-level exams.  JNCIA is the base exam that all other certifications require, building on concepts and foundations of the Junos Operating System.  Building up from that, are the "Specialist" exams.  In Cisco parlance, they would be the equivalent to the CCNA certifications. Juniper release...

SDN Should Not Require Programming – Per Se

Provided as-is, with permission by Creative Commons 2.0, and courtesy of Libby Levi for opensource.com.
There has been a lot of controversy about how the network engineering profession will change in the future, thanks to SDN (Software Defined Networking).  Because network decisions will now be controlled by software, many think the network engineering profession will have to learn programming.  While this may be true in some cases, I do not believe it to be true in the majority of the cases. If you break down the acronym, it will say "Software-Defined" networking.  This means software that has previously been written to accomplish a specific task will be deployed on the network.  Do you need...

HP Tech Day was a great success. The discussions and presentations centered around HP’s converged systems. Probably the presentations that received the most attention and interaction was around HP OneView and VDI. The beginning of the day started well and included presentations about the benefits of converged systems and then a future planning of the use for converged systems. HP OneView HP OneView is becoming the standard provisioning and management package for HP’s end-to-end solutions in the datacenter.
