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...

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...

HP Tech Day was a great success. The discussions and presentations centered around HP’s converged systems.

Upgrade HP Switch using Intelligent Management Center

Earlier this year, I had a need to upgrade 2 HP 5406's.  These switches (commonly used as aggregate switches) are used as a central core for an office of approx 500 nodes.  These switches are used in redundancy using MSTP and OSPF.  The below video shows how easy it was to upgrade the equipment.

Using HP Intelligent Management Center for IPAM?

stock_IMC_mgmt
HP's Intelligent Management Center, or iMC, is a fantastic Network Management System (NMS).  It is very scalable, and very modular.  For those that know me, or read my posts, you'll know that I quickly fell in love with this product.  And I'm always learning something new with it each day. Why IPAM One of the challenges of today's infrastructure groups, is to get a handle on IP Address Management.  When you were on a small network, spreadsheets really did the trick.  It was easy to use.  But, it was flat and could not keep up with the changes and advanced uses of today's subnets.  Especially...

HP IMC Topology Views

HPNIMC_cropped
The topology screens on HP's Intelligent Management Center can be fun, informative, and very intuitive for lower-skilled technicians.  Granted, I'm not one for alot of eye-candy.  Having graphical representations on a wall or screen is not very informative for me personally.  I'd rather see an alarm or event listing.  But, from a technical support standpoint, it's useful to give support personnel a high-level overview of the entire network (or, at least, a view of their respective responsibilities). IMC has multiple levels and views for Topology: Datacenter Topology - This topology view...

Intelligent Management Center Tacacs Fails to Authenticate

We all have our preference over AAA protocols. The most popular being RADIUS, with TACACS+ having a following only due to historical momentum of the company using it. DIAMETER is slowly coming to the market due to it’s more ‘enhanced’ capabilities, but it’s hard to change from “what works”. And TACACS+, my friends, just works. I won’t go into detail on why I love that protocol, but instead, tell you about what I learned today. Why move away from tac_plus? For years, I’ve been using the tac_plus daemon to do all of my AAA (Authentication/Authorization/Accounting) needs. It’s free, it’s so...

Writing Good Solutions – The Short Guide

Writing Good Solutions
I have a problem.  The canooter valve has gotten stuck from a flux-capacitor overload.  Because of this, a server's warp-drive has gone critical.  We have received almost 50 calls so far that user's plasma-coils are popping.  Everyone is looking to me to fix it.  What am I to do? I do like every other great technician/engineer does.  We research.  First, let's check if we've seen this before.  Login to ticketing system.  Check.  Navigate to solutions database.  Check.  Search for "canooter valve plasma coil".  1 result: "Canooter valve frozen.  Reset the plasma coil.  Popping stopped" Oh,...

Robotics and IT Management

After a week of travel to Europe for work, I am winding down at a restaurant in Stockholm Arlanda Airport for a flight in the morning.  I decided to go and have one more nice meal (and some wine to help me sleep).  Okay, the wine was for taste, but the sleeping part is an added bonus.  During my dinner, I noticed some perfect english beside me (which is rare in Sweden). After introducing myself, I found out it was a group of people who just finished a week from a Robotics conference discussing papers (one PhD and 2 undergrad).  What a fantastic discussion!  Especi...

Custom Functions for HP IMC

One of the best features of HP's Intelligent Management Center is not that it's modular and can do so many different things.  It's not that it's scalable, and can handle tens of thousands of managed devices.  It's not even it's alarming and event system.  No, the best feature of HP's IMC, is that you can do things that it wasn't programmed to do. Take this use case for example.  As a network administrator, you are constantly being blamed for poor access into the network.  After drinking 3 cups of coffee and reviewing everything at your desk, you see nothing wrong. ...
