Upgrade HP Switch using Intelligent Management Center

stock_IMC_mgmt
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...

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...

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. ...

Looking forward to HP Discover 2013

  HP Discover is a fantastic event.  I’m not kidding!  It is absolutely remarkable! You don’t have to be an avid HP-lover to attend.  It’s not a requirement.  But the technology, information, and people at these events ARE NOT to be missed!  Not only does HP put on a massively impressive show, but I am ALWAYS geek’ing out with… well…. If I say “talented” people, I would be at a loss.  They are beyond talented, and I learn so much at this event!     Truth be told, I probably would not attend this event on my own.  I couldn’t afford ...

Can’t authenticate Cisco to HP iMC Tacacs

I love TACACS+.  I know there are those of you who prefer RADIUS, but there are a few reasons why I love Tacacs It's tried and true.  Stable It's TCP not UDP (c'mon, you knew I'd use this...) It's easiest to configure Group -> Command mapping So, when HP iMC 5.1 came out with TAM (Tacacs Authentication Module), I just HAD to try it out!  So, I grabbed a lab switch, downloaded the trial version of TAM, and started hacking away.  It wasn't long before I was stuck.  No matter what I did, I just couldn't authenticate to iMC.     I chec...

Installing HP iMC with remote SQL Server

When installing HP Intelligent Management Center, you have a choice on where to store your data. If you are on a Windows system, your options are SQL Server or Oracle. When installing on a Linux system, your options are MySQL or Oracle. Initially, my install was on a Linux system (CentOS), for reasons beyond the scope of this post. I installed MySQL and setup all the configurations as defined in HP’s “MySQL 5.5 Installation and Configuration Guide (for Linux)” guide. Everything worked great. MySQL server was up and running, and I was able to connect to it with other tools. But, iMC would n...

HP Intelligent Management Center – Service Health Management

20 or 30 of us walk into the next HP Discover 2012 break-out session titled “Understanding Service Health Management in iMC”. Les Stuart begins the presentation with the overview of SHM. Chris Young, Solutions Architect for HP walks to the front and asks a single question, “How healthy is your network?”. Now, as you can imagine, most didn’t know how to answer it, and after waiting about 15 seconds of mumbling and crazed looks, people began giving different answers. That’s to be expected, since everyone determines that differently, depending on your responsibilities. The Server guys think t...

Interview of HP’s Saar Gillai on SDN

During HP Discover 2012, I've been asking various HP divisions on the plans HP has for an OpenFlow controller.  The reason?  For the last 18 months, I've noticed that every HP event mentions SDN and OpenFlow.  Why?  Just adding support for a technology is not a big deal.  One, maybe two announcements, and you are done.  Why so much talk about it?  Surely this means that HP has big plans for it. The answer I get back is, "What would you do with one today?".  Well, nothing, TODAY.  The enterprise doesn't really have a need for it yet.  But th...

HP iMC iPhone app

Well, everyone keeps talking about it.  It's on the web site, and in the documentation.  A mobile app for HP's iMC?  View alarms and device details?  Sign me up.  But, just EXACTLY where is it?? Some HP Solution Architects (Thanks Kurt Weil and @netmanchris) pointed me to the following link:  http://itunes.apple.com/us/app/imc-manager-client/id488031041?mt=8 So, I installed it and started looking around.  This is a needed app, as many techs and engineers are usually up and around.  Either in server rooms, wiring closets, or meetings.  Wouldn't...
