Cisco Smart Install

Cisco Smart Install

This is my first post in a new series called “Config Bytes”.

My objective is simple. Take a technology that I’m working on with a customer and post the data points.

Overview:

A global company asked me if there was an easy way to provision switches for rapid deployment. They are somewhat limited on networking personal and this would save the team some time if they could automate the staging of switches before deployment . The basic requirements were a standardized image depending on the platform and initial config for access switches. I had two viable solutions to match these requirements 1) Prime Infrastructure Plug & Play 2) Smart Install

2015-03-24 10.56.32 am

Smart Install:

Since the launch of the 3850/3650 access layer switches, we had slides that mentioned all the value add features of the Catalyst line. One of those bullet points was smart install and I remember this for the 3750x as well. At the end of 2014, we put out an updated configuration guide for smart install. I used this as a basis for design and configuration. http://goo.gl/mtYrha

You can read up on all the details, but let me summarize a few key points.

  • Smart Install is a plug-and-play configuration and image-management feature that provides zero-touch deployment (ZTD) for new switches. You can ship a switch to a location, place it in the network and power it on with no configuration required on the device.
  • Two roles for the switch infrastructure “clients” & “director”
  • Director can be an multilayer switch or router
  • Clients connect to director and pull down image and config without any intervention (ZTD)
  • If a client switch was already deployed, you must “wr erase” and reload without a startup-config for smart install to work. Out of the box, no intervention required.
  • If using an L3 switch for director the smart install “vstack” VLAN must be up or the director can fallback to a client role. Just make sure the VLAN has at lease one access port up/up if using that SVI for the director.
  • TFTP and DHCP services are required, however they can co-reside on the director. This is how I configured it in the example inline.
  • Make sure your director device has plenty of flash memory to store the images and configs. If you have many different PIDs, your going to need more flash. I found that 2GB on the 3650/4500x was suffice for my customer.
  • Be patient while the image is loaded to the client. This process takes time (sometimes up to an hour).
  • I found that using the .tar format for the images worked the best. I’m not even sure if the .bin format is supported.
  • If you want to verify the supported clients on the director use this command “show stack group built-in ?”

The Best Games of 2014

The Best Games of 2014

I am the Law!

It’s that time of the year. The time we enjoy with our family, friends, and stuffing our faces with pie. This year left a painful scar on many gamers eager to play their 8th generation console on Christmas day. Both PSN and Xbox Live were hacked (DDoS) and taken offline. That means, no console updates, no digital downloads (sorry bundle owners) and no multiplayer. It’s come to the point where we need to institute a new law regarding those responsible for cyber crimes. You get caught, you get your ass beat hard. No questions or trial, just a good old fashioned ass whuppin and public humiliation.

Plays out like this. Haxor in the basement of his moms house drinking 64oz monster and eating doritos. Window smashes in and tiny black canister rolls into the room. What follows next is the sound of Mjolnir’s hammer dropping and the power of 7M candles burning your eyes. You can’t see and your disoriented crawling on the floor. Your head feels like it’s going to explode from the pressure, but you mange to stand. BAM! Your hit square in the jaw and fall back to the floor HARD. Your body is taking blows from all angles as your struggle to maintain consciousness. You fail and your drift into a black abyss. You finally open your eyes and realize your sitting in the middle of town, without any clothing on. There is a sign on your neck. “I’m a hacker that was caught. EPIC FAILURE”.

OK, back to reality. Normally, I would have been impacted by this outage because Christmas is a great time to scratch my gaming itch. This year was different not really by design, more like chance. Typically, I’m a console gamer and logged on PSN trying to rack up the trophies. So, it’s a shocker that my #1 GotY goes to…

#1 Game of the Year (Multiplayer)

Titanfall (PC)

I have a pretty big exam that I’m studying for and that’s taken up much of my cycles. The little time I have, I spent playing Titanfall. Not on the xbox, but on the PC. You see, I’m not going to bore you with a list of FPS games in this post, just get right to the point. My #1 MULTIPLAYER game of the year is Titanfall. The reason? It’s simple really. It’s more fun then throwing Hans Gruber off the 30th floor of Nakatomi Towers and it has everything (sans a good campaign)! Red balls level twitch shooting, balanced gameplay, great sound, amazing graphics on the PC (Ultra settings, never dropped below 60fps), awesome weapons, and brilliant execution of mech/pilot cat/mouse mechanics. Perhaps, I’m biased here. I can remember playing Mechwarrior 2 on the PC back in the day for an excessive amount of time (we are clan wolf, arcadia is our destiny and our right). There is something short of magical piloting a 100 ton mech and hunting your pray. Find them and send a barrage of guided missiles with 40mm shells for good measure up their steel butt. They try to escape, you pull the pilot from the mech and squeeze them like fresh oranges on a hot Florida morning. If John Wyane’s your thing, then hop on top of a mech while you rodeo your way to success. If your not with me on this, then perhaps we can agree that a sexy female AI voice is all any good shooter needs. <GRIN>

For the record: I built a new gaming rig with the intention of playing PC exclusives I missed over the years. Titanfall was only $9.99 during black friday. Not only is it my multiplayer GotY, it’s also my “kick ass bargain” game of the year. PC gaming, oh how I missed you!

PC Specs: i5 4690k, 16G of DDR3 2133MHz, GTX 970 superclocked, gigabyte sniper G1.M5, Samsung EVO 840 pro SSD, and xbox 1 controller.

#1 Game of the Year – Single Player Campaign 

Bayonetta 2 (Wii U)

Is there really anything else I need to say about this game other than the title? Just look at these amazing in-game “graphics”. Feast your eyes on that and if you haven’t played it, do yourself and go buy it NOW! My only complaint is that the game is over too quickly.

Rodin says, Merry Christmas! Now go buy this game or He’ll (get it?) come looking for you.

December 24th, 1990

I was twelve years old and twelve days away from becoming the BIG thirteen. This Christmas was very special indeed. I was getting a “combined” Birthday and Christmas present. Oh boy, was it special! I was sitting there with my family, my hands trembling because I knew exactly what lies beneath that red paper surface.  Just a few hours ago I was playing 720 on the NES on a small color TV and thinking how awesome Altered Beast is going to look. An ARCADE experience right in my living room. By contrast, 720 looks NOTHING like it’s arcade counterpart. My younger sister went to bed and this year I could stay up until midnight and open my gifts. I cared nothing about the other “stuff”, just that giant red present. I was moments away from tearing into this thin red barrier that stands between me and the most memorable Christmas present I’ll ever receive. 11:59 > GO!

It was indeed a Sega Genesis and E-Swat: City under Siege! I probably set a record time for setting it up to the living room TV. I powered up the Genesis, smirked at the “16-Bit” etching on the top because I was an elite, then I heard this. “Rise from your grave”

My jaw hit the floor. Digitized voice, giant sprites, 64 on screen colors out of a 512 palette, and a 16-bit processor (motorola 68k). I was playing a reproduction of the arcade game in our living room. More digitized voice would come out of the famous Yamaha 2612. “Power Up!” and then “Welcome to your Doom”. Man, I was living the dream right here. All year, I was waiting for this moment and it was glorious. My family watched me for a few minutes and then dispersed. I put some headphones on, cranked up the volume slider, and stayed up until I finished Altered Beast and played the first level of E-Swat. Here we are, 24 years later and I remember that day like it was yesterday. That is the kind of impact Sega had on me.

Promise

I made a promise with the author of Console Wars, Blake Harris @blakejharrisNYC via Twitter. That promise was a FULL review of his book after I had time to digest and process my thoughts. The topic of video games (retro especially) is something I’m very passionate about like many of you reading this post.

I plan to fulfill this promise and thank you Blake for caring enough to ping me on Twitter about my sentiments of your book.

The Recommendation

On May 22nd, 2014, I’m walking through the Cisco Live world of Solutions in San Francisco and ran into fellow gamer and TechWiseTV co-host Jimmy Ray. Now Jimmy Ray and I have a mutual bond when it comes to things that go fast and video games, so I proceed to tell him about me being a speaker for the first time at live and how I managed to incorporate video games into my presentation. He then tells me about this book called Console Wars and how it just came out. He basically said this and I’m paraphrasing a bit because Jimmy Ray talks so fast. “Dude, you got to get this book it’s really cool”.

So, on that sound advise, I ordered the book from my hotel room later that evening. I actually didn’t realize the book was only out for nine days, I thought it was something that I just missed. Well… I had to wait until the 28th to receive my PAPERBACK (that’s how I roll) and that very night started my journey back in time.

I read it cover to cover (558 pages) in 3 days. By the weekend, I was summarizing my thoughts and my overall verdict was quite different then what I expected.

The Review

WOW! This is one of the best books I’ve read about marketing strategies. That was my overall initial impression. This is very different from what I was expecting. I was thinking it was going to be a geek out retro fest about the deep secrets between Nintendo and Sega and the culture clash between the Japanese developers and American consumers (some of which is the case).

Let me just start of by summarizing the overall premise. David (Sega) vs. Goliath (Nintendo)

Excluding the Foreword (don’t waste your time on this part, it’s just a bunch of ramblings) by Seth Rogan and Evan Goldberg, the book had me hooked from Chapter 1. The tale begins with Tom Kalinske (former Matchbox and Mattel CEO) on a beach with his family. He receives an offer from the then president of Sega, Hayao Kakayama that was too good to refuse.

From this point on your whisked away into the inner sanctum of Sega R&D, this history of Nintendo, excessive costs of licensing/royalty, game concept idea conception, lock out chips, culture clashes, Sonic vs. Mario, 16-bit to 32-bit transition, and the actual marketing proxy wars that took place between all this.

My personal highlights are the following.

  • The origin story of Sonic the Hedgehog
  • Thomas Kalinske’s journey as president of Sega of America
  • Nintendo of America was saved in 1981 by Miyamoto-san’s Donkey Kong (originally a Popeye game) and then Seattle lawyer Howard Lincoln. History would then repeat itself in 1994
  • Japanese dudes smashing stuff
  • Sony Playstation origin story and the greatest marketing presentation ever. Read the book, I won’t spoil the surprise.
  • The various victories of an underdog
  • The creative marketing tactics, which many are still in use today. I should know, I’ve been in sales over 7 years now.
  • The awesome Sonic 2 marketing campaign

I’ll end my review on this simply message. If your into video game history, this book has it ALL. It your into business sales and marketing, this book has some great insight. Enough reading my post, go get this book and start your journey on the road of gaming nostalgia.

Cisco Modeling Labs 1.0: First Impressions & Getting Started

Cisco Modeling Labs 1.0: First Impressions & Getting Started

2014-09-16 01.30.37 pm

When a Legend becomes Real

I’m still pinching myself. Last week I delivered my very first Cisco Modeling Labs (CML) 1.0 demo to a customer. Overall, they were pretty darn excited, however there are some things that we need to address to make it a GREAT fit for their specific testing/validation environment.

Let’s take a step back and talk high level about CML for a moment. CML is the Cisco TAC supported variant of VIRL. The FCS date for CML 1.0 was 08.11.14. Almost a month later and several hours behind the wheel, I can say it was totally worth the wait. If your looking for a deep dive into the architecture behind the scenes, check out my previous blog post on the subject.

Let’s start with some of the most important aspects of CML to set expectations accordingly.

  • CML is NOT an emulator. The CML images are compiled specifically for the virtual machine environment (KVM). This is how you can scale to 150-200 nodes. It’s actual IOS/XR/XE/NX-OS code optimized for the VM. I was a huge fan of GNS/Dynamips, but the scale always left something to be desired. This is one of the major issues with emulation, PERFORMANCE.
  • CML WILL NOT validate ASICs, line cards, or any other hardware specific functionality/behavior. If your getting CML for this reason, it will NOT be a good representation.
  • CML is GREAT for config verification and migration/functionality testing. For example going from single IPv4 stack to dual stack, testing PfR configs, IGP configs, route policies, etc…
  • CML will also be GREAT for testing new code and features. The BU’s are committed to updating the CML images. For example: My IOSv image is 15.4(2)T1 which is pretty recent.  “IOSv Software (VIOS-ADVENTERPRISEK9-M), Version 15.4(2)T1”
  • CML is GREAT for troubleshooting problems in an isolated environment.
  • CML allows you to integrate the virtual simulated environment with the physical lab network.
  • CML images available TODAY/09.16.14 are IOSv (included with your 15 node base license), IOS XR, and IOS XE in the form of CSR1000v. There is also a Linux server image for hosts.
  • CML team recommends UCS C220 M3 server or C460 M2, but you can really bring your own hardware for the host. ESXi 5.0, 5.1 or 5.5 is REQUIRED. Check out this URL for the data sheet and requirements. 
  • There is NO cloud/hosted offering of CML.
  • Be sure to check out the CML Q&A for anything I may have missed.

Craig Brown (TME): Cisco Modeling Labs Overview

Getting Started (see inline for ordering info)

  1. Download the install guide
  2. Setup your ESXi host
  3. Download the CML OVA
  4. Deploy the CML OVA
  5. Run through the “First Time” scripts on the Ubuntu guest
  6. Install the necessary license keys
  7. Add any additional images (IOS-XRv, CSR1000v, linux server)
  8. Download the CML client (OSX or Windows) from http://IP_OF_CML_SERVER/download
  9. Connect to the CML server
  10. Design, Build, Visualize, Simulate

This is a really just an overview. Your gonna want to go through the install guide and ensure your following the requirements and recommendations. I’ll be posting an instructional video on youtube shortly with a step-by-step guide on how to get started.

Caveats

  • Only GigE virtual interfaces are supported currently. No serial interfaces or 10G/40G
  • Additional images (IOS-XRv, CSR1000v, etc) must be purchased separately. Only IOSv is included with the base license
  • Modeling of traffic patterns (traffic flow creation) are slated for the CML 1.1 release

Thoughts and Closing

In closing, I hope your as excited as I am about CML. It’s been a long time coming and I’m really glad the CML team took the time to get this right. I see many applications for CML in my personal journey. Let’s start with my home lab. I’m blessed to have access to Cisco hardware, but my lab gets HOT and my electric bill goes through the roof. I’ll use CML to validate customer configs, design and test IWAN/PfR configs, CCIE DC studies (NX-OSv image), EEM applet validation, and routing configs. Hopefully this saves me from the hundreds of dollars in electric to run a cat6500 and nexus 3k’s at home. 🙂

I used GNS3/Dynamips and IOU/IOL for many years. I will just say this, CML blows them away. I love GNS, but my problem has also been two fold. Scale and relevance. With regards to relevance, I was running the 7200 image and old IOS code. It’s just not current enough and emulated platforms suffer when it comes to performance. IOU/IOL is internal to Cisco only.

If your wondering about VIRL personal edition, my understanding is we’ll eventually release this to Cisco DEVNET. I just don’t have any committed date (update Dec 1st, 2014) at this point in time. This is going to be great for those studying for Cisco certifications from the CCNA to CCIE level.

If your interested in a 30 day trial of CML, reach out to your Cisco account team.

I hope you found this post informative and helpful. If you have any suggestions on how I can best demonstrate CML, please leave feedback. I’m going to talk to the CML team and see if they plan on conducting a WISP lab at Cisco Live next year. If not, I’ll be hosting one. It’s that good. EVERYONE needs to see it.

UPDATE: I’m told by one of the TME’s that CML will be demoed at Cisco Live, Cancun in Nov.

Next Wave of UCS Innovation

Next Wave of UCS Innovation

Today was a BIG day for us at Cisco. We announced our next wave of UCS products and continue building our data center innovation superhighway. Did we announce one product? NO! We announced four major UCS products today at #UCSGRANDSLAM and it was AWESOME! I knew about this stuff for months, but had to keep quite. As you can imagine, I was at the point of imploding because I just wanted to share this info with EVERYONE. Here is a quick recap of the UCS portfolio expansion announced today.

  • UCS Mini provides the full power of Cisco Unified Computing in a smaller, all-in-one solution that is simple, easy to manage, yet expandable. Great for IoT/IoElocal processing (Fog) and ROBO customers. 

2014-09-04 03.38.09 pm

  • UCS M-Series Modular Servers for Online Content Providers and Cloud Service Providers and for distributed applications in Industrial High Performance Computing (HPC) and Enterprise Grid. What about dedicated hosting and cloud services?

ucsm

  • Cisco UCS C3160 Rack Server is a modular, capacity-optimized solution ideal for distributed data analytics, unstructured data repositories and media streaming and transcoding. I have one customer looking at this now for vSAN. 

2014-09-04 03.39.28 pm

  • Cisco M4 Generation UCS Rack and Blade Servers are armed with the latest processing power providing increased performance, efficiency and computing density. Intel Haswell architecture, E5 v3. 

2014-09-04 03.40.40 pm

All that said, I’m ecstatic about today’s announcement and can’t wait to hear from our customers on the challenges that can be overcome with these latest additions to the UCS family. I think about five short years ago when naysayers said Cisco had NO PLACE IN THE SERVER MARKET. They were WRONG! We are #1 in the US and #2 worldwide in the x86 blade server market. I’m confident we’ll be the #1 server vendor worldwide in no time at all.

UCS | Powering Applications at Every Scale

As soon as the video of today’s announcement is posted, I’ll link it here. Stay tuned!

PREFACE

I wanted to take a few moments and give an update on CML/VIRL. I have had many inquires from my clients about CML/VIRL, it just makes sense to summarize these conversations and post something for those of us that can’t wait to get our hands on the first customer shipping (FCS) of CML/VIRL. ***IMPORTANT*** CML is the TAC supported version of VIRL. Just keep this in mind when we get into the “When” section of this post.

Who?

First off what the heck is CML/VIRL? CML started off as a project called Virtual Internet Routing Lab (VIRL) and is a graphical front-end to virtualized networking devices. Hold the phone! That sounds like IOU/IOU-WEB or GNS/Dynamips… What makes CML/VIRL better? Glad you asked. With GNS3/Dynamips your emulating the ASIC/CP-CPU hardware and running the actual IOS image on that emulated node. Each node is emulated and in the case of GNS3/Dynamips your choices are limited to older hardware such as 2600 and 7200 series routers. The images supported are only the monolithic IOS images and not the newer IOS-XE images found on newer routers such as the ASR1K and 4451x. I have ALWAYS had GNS3/Dynamips on my laptops as a quick and dirty syntax validation tool and for small scenario recreates (BGP peering configs, ACL validation, etc…). It’s especially useful in offline environments like studying for the CCIE R&S on a coast-to-coast flight. But, alas all was not good. My hardware choices were limited and the topologies were small because if they grew too big, my MacBook would become a personal space heater. This brings me to my biggest complaint about Dynamips, performance. Because the complete hardware is emulated to accommodate the original IOS image, it’s as slow as a Smart FourTwo (slowest 0-60 car). With CLM/VIRL each node is a virtual appliance that runs images designed for x86. The hypervisor is KVM/QEMU, Openstack is the orchestration, VM maestro is the graphical topology edition tool, and AutoNetKit is used for network configuration and rendering. This allows your lab/topology to scale much better then Dynamips or IOU, have better performance, and introduce other appliances into the environment such as a linux jumpbox or any other appliances we decide to support (no commitments here, just theory). 2014-07-09 12.23.51 am   2014-07-09 12.42.18 am Now for a dose of sad news, L2 appliances are not supported in CML/VIRL. Perhaps in the future this may be different, but for now it’s L3 only. You do get the vswitch within KVM, so it’s not a total bust. In fact, this is a critical component as connecting your lab devices together and connecting the virtual world to the physical world. Also, no serial interface support, Ethernet only. Again, perhaps this will change down the road…

What?

What virtual appliances will be supported? 1) IOS-XE: VM CSR1000V 2) IOS-XR: VM XRVR 3) NX-OS: VM vNXOS 4) IOS: VM vIOS 5) Servers/3rd party appliances Host OS is ubuntu server v12.04.2 2014-07-09 12.24.06 am

When/Where?

This is my number one question from clients. I personally first saw VIRL back at Cisco Live US 2013 in Orlando, FL. They had a demo setup just outside the WISP labs. That year I hosted my own WISP lab (Nexus 3548 Algoboost technology) and got to spend a decent amount of time playing with the beta and talking to the team. Keep this key factor in mind. There are two VIRL platforms.

1) Individual customers

2) Corporate customers

For individual customers the target is July 30th, 2014 TBD and will be available to ANY customer registered on Devnet. This is community supported. For more information on ‘Devnet’, please take a look at https://developer.cisco.com/site/devnet/home/index.gsp. For corporate customers joining the “dev-innovate” program. VIRL will be included in the software bundle. http://dev-innovate.cisco.com/ For corporate customer looking for a TAC supported VIRL, this is the CML product and the target date is July 15th August 11th, 2014. ***Disclaimer*** Target dates are subject to change 

Why?

Because your tired of getting burns from your laptop after running a 14 node simulation in GNS/Dynamips or you don’t want to deal with getting the right image for IOU/IOL (Cisco employees of course) <GRIN> In all seriousness, I personally have been looking for something more realistic/serious for a test/dev environment. There are many times where customers ask for input on designs and I want to validate a theory via syntax before making a recommendation. I have done this for over 7 years with either real hardware (sometimes VERY expensive) or dynamips, albeit to a much smaller scale and with those limited node selection. My other major driver for VIRL is one of my customers is an ASR 9K shop and I don’t know IOS-XR that well. What better way to learn and save on my home lab electricity bill? Here are some of the “official” use cases.

  • Learn or provide training on new IOS versions or releases without the cost of purchasing, deploying, and maintaining expensive hardware
  • Stage and / or develop device configurations ahead of actual deployments
  • Test new software capabilities without impacting actual networks or hardware
  • Evaluate changes to network architectures or configurations – what-if scenarios
  • Trouble-shoot or diagnose control- or management-plane issues without scheduling network maintenance windows
  • Create and connect virtual instances of new hardware or solutions to real, existing networks to evaluate their impact, performance, or behavior

Each of these activities – prior to VIRL – required expensive hardware resources that were both static and costly.  VIRL on the other hand allows complete flexibility in terms of the architectures that can be created, limited only by the compute resources (which are significantly less costly than network hardware) that can be dedicated for use.

How?

Deploy the Ubuntu VIRL OVA of course… Just kidding! While getting started really is that easy, getting everything setup and configured is a little more involved. There will also a bare metal installer. I’ll be updating this section shortly when more public information is available. The resource requirements are pretty high for laptop/individual deployments. For example XRv requires 1.3GB of RAM (real or swap). Keep this in mind as it will limit how many VMs can be run. Real world customer deployments will be based on properly sized UCS servers. Mac (OSX 10.7+) /PC (Windows 7) minimum requirements: 8-16GB RAM (4-8GB for VIRL) and 20GB of disk space 2014-07-09 12.41.25 am

Summary:

VIRL enables customers to support many critical missions – designing, training, release-testing, configuration-staging, and others – without the expense of buying and staging real network hardware.  Networks of any complexity can be created and tested using the same software that will run on the real routing platforms.

The cost of network hardware required for training, testing, certification, pre-deployment, and other non-production activities can be a significant burden for customers – from the lone individual studying for CCIE to the largest of SPs.  VIRL, by providing the ability to deploy large, multi-OS virtual networks on comparatively inexpensive compute platforms, can significantly reduce both capital expenses and the expenses – both monetary and time-wise – associated with deploying hardware for non-production activities.

If you found this post to be helpful, please leave feedback.

Thanks!

Retro Gaming Gomez (RGG)

Retro Gaming Gomez (RGG)

RGG, I like the sound of that! I just back from Cisco Live in San Francisco and what an AWESOME time it was. This year I was co-hosting a session with my homie Matt. The session title was “Software Hot, Hardware still Cool” and was SDN related. We had a blast working on this project together and aside from our session time going from 90 minutes to 60 minutes, it was an excellent experience.  So, part of my shtick with “Hardware” was drawing a contrast between software and hardware. It’s impossible to extract the full potential of hardware without excellent software. Great software will ALWAYS sell the hardware. This is true in the video game industry as well as the network infrastructure business. I love an example cited in the book (Console Wars). “the console is the movie theater, but it’s the movies that kept people coming back for more” Another good example of this is when I switched to Mac/OSX. I had great hardware, but the software (Vista!) was terrible. My system would BSOD all the time. Windows 7 was WORLDS better and I hear Windows 8.1 is pretty good, but since I moved to OSX, I honestly have not had a reason to migrate back to Windows. For me, OSX just seems to work better for MY intended purposes. In the networking world, we recently posted NX-OS 7.0 for the Nexus 6000 platform. This version of code woke 22 great features up in hardware that were taking a nap. One of which is a latency, buffer, and micro-burst monitor. In the video game world, you look at a 7th generation console like the Xbox 360. Gear of war 1 looked amazing when it was released and we all thought, wow! The graphics, textures, and lighting could not be any better… WRONG! Look at Gears 3. It’s hard to believe they are the same console, that’s how far advance the graphics became with software that unlocked the maximum potential of the hardware.

gow

Another 7th generation game console, the PS3 has another good comparison. Resistance Fall of Man vs. Last of Us.

resistence

lous

You get my point, here. To quote one of my favorite movies Tron Legacy: “I Took the System to it’s Maximum Potential” – CLU

So, this story I told is just a backdrop to my “real” post. I like the sound of “Retro Gaming Gomez”. I think I’ll start a YouTube channel dedicated to retro games using this name. I have a specific theme for the channel, but that is something I want you to linger on. I want this channel to be unique and intriguing. Thanks Johnny (@HCGSHOW) for the encouragement and advice. 

So, what qualifies me to bestow such a grand title as RGG upon myself. Well, I think pictures are worth a thousand words and right now I only have a little over 400 words. Let these AWESOME pictures fill some white space.

This is but a sample of my retro gaming passion. I have played (and finished) thousands of games beginning with my 1st generation console the woodgrain Atari 2600 to current 8th generation consoles like the Playstation 4 and Wii U. In fact, unlike many collectors. I actually try to play and finish EVERY game I add to the collection. Now, the most important thing that you MUST know about me. Especially if you intend on subscribing to my show. I love ALL games. This is my personality. I NEVER cared WHO (Sega or Nintendo) made something, I loved them ALL. Marketing was VERY creative in the early 90’s, but both Sonic and Mario were great games that sold the hardware. I just wished at the time I could afford EVERYTHING, but that was not in the cards. THERE WILL BE NO FANBOY TALK, PERIOD. This personality trait transcends gaming for me. Android/iOS, Cisco/Juniper (OK I’m a little biased here…), Microsoft/Apple, VHS/Beta, Hammer/Screwdriver, etc… In general, I love it all, it’s just that certain tools work better at specific jobs. 

So, stay tuned for the launch of my “official” YouTube show titled Retro Gaming Gomez.

Gamers, Stay Frosty!

 

CCIE R/S v5: Everything’s Gonna be Alright

CCIE R/S v5: Everything’s Gonna be Alright

facepalm

It’s been roughly five months since I passed the v4 CCIE R/S and I’m starting to hear potential CCIE R/S candidates freaking out about the upcoming changes. I know this feeling all too well, because like many of you I started on v3 and passed on v4. I will never sugar coat this, it’s a royal pain in the arse when the blueprint gets revised, especially if you have been studying (really studying) the current blueprint. That being said, I generally love what I see with the v5 blueprint and believe it’s best for the program to evolve and stay relevant. Let’s take a look at these changes and I’ll do my best to summarize what I know so far.

Six main pillars for written and lab.

1.0: Network Principles
2.0: L2 Technologies
3.0: L3 Technologies
4.0: VPN Technologies
5.0: Infrastructure Security
6.0: Infrastructure Services

Why do I like this? Well they really just consolidated the 11 topics from v4. Since we are not only dealing with MPLS VPN, but also IPSEC VPN/DMVPN it makes sense to group these together under “VPN technologies”. IPv4/IPv6/L3 multicast/routing protocols are now grouped under “L3 Technologies” and “Network Principles” is really only applicable to the written (in the “real world” this is a prerequisite) and completely new to the blueprint. “Infrastructure Security” will cover technologies such as router and switch security features, but also PKI/crypto. Finally, “Infrastructure Services”. Expect things like management, QoS, services, optimization, etc here. I would imagine since they are moving LAN QoS OFF the lab and into the written, things like SRR/WRR/RSVP are GONE. Thank goodness!!!

Not so bad right? Well let’s talk more about what was taken off the written and lab.

Topics Removed from the CCIE RS v4.0 Exam:

• Flexlink, ISL, Layer 2 Protocol Tunneling
• Frame-Relay (LFI, FR Traffic Shaping)
• WCCP
• IOS Firewall and IPS
• RITE, RMON
• RGMP
• RSVP QoS, WRR/SRR

If your like me your excited to see things like WCCP, IOS FW, and RSVP go bye bye. I did scratch my head on one of those subjects perhaps it’s because I spent so much time on the technology, Frame Relay. The only reason I say this is because many carriers are still using frame relay as the encapsulation for MPLS VPN solutions on TDM transport. This is going away, but it’s still out there in production just at a much lesser degree then 5-10 years ago. Still, I’m sure many are happy to see my good old friend Frame Relay put out to pasture.

Let’s continue with the subjects moved to the written, but removed from the lab.

Topics Moved from the CCIE RS v4.0 Lab exam to the CCIE RS v5.0 Written Exam:
• Describe IPv6 Multicast
• Describe RIPv6 (RIPng)
• Describe IPv6 Tunneling Techniques
• Describe Device Security using IOS AAA with TACACS+ and RADIUS
• Describe 802.1x
• Describe Layer 2 QoS
• Identify Performance Routing (PfR)

Oh man, there are so many on this list that I’m happy to see go to the written. Where do I begin… PfR!
PfR could be an exam of it’s own. If you don’t believe me go and configure a complex policy with multiple probes and get back to me with a verdict. Very happy to see 802.1x and v6 multicast move to the written as well. I kind of liked the ipv6 tunneling stuff on the lab, but that’s just me. GOODBYE RIPng, sorry nobody ever used you.

Now the fun begins. Here are topics that were added to the written, but not in the lab,

Topics Added to the CCIE Routing and Switching v5.0 Written Exam:
• Describe basic software architecture differences between IOS and IOS XE
• Identify Cisco Express Forwarding Concepts
• Explain General Network Challenges
• Explain IP, TCP and UDP Operations
• Describe Chassis Virtualization and Aggregation Technologies
• Explain PIM Snooping
• Describe WAN Rate-based Ethernet Circuits
• Describe BGP Fast Convergence Features
• ISIS (for IPv4 and IPv6)
• Describe Basic Layer 2 VPN – Wireline
• Describe Basic L2VPN – LAN Services
• Describe GET VPN
• Describe IPv6 Network Address Translation

ISIS? OK, so FabricPath and OTV leverage ISIS under the covers, but really adding it back to the written? Poor ISIS, your hot then your not, then your hot again. One word comes to my mind “pong”.
I like the IOS vs IOS XE, PIM snooping, switch virtualization, BDF/BGP, and CEF topics. GET VPN? Well, I guess someone is using this out there for it to be put on the written exam. Overall these additions to the written seem to allow Cisco to vet out candidates for the lab a little better and bring the curriculum a little more current.

“The decisions regarding which topics should be added, moved or retired were based on feedback received from key industry Subject Matter Experts (SME). These decisions reflect the evolution of the expectations of a candidate performing on the job role.”

I will agree with that quote. It’s from the learning@cisco exam update for v5.

Topics Added to the CCIE Routing and Switching v5.0 Written and Lab Exams:

• Use IOS Troubleshooting Tools
• Apply Troubleshooting Methodologies
• Interpret Packet Capture
• Implement and Troubleshoot Bidirectional Forwarding Detection
• Implement EIGRP (multi-address) Named Mode
• Implement, Troubleshoot and Optimize EIGRP and OSPF Convergence and Scalability
• Implement and Troubleshoot DMVPN (single hub)
• Implement and Troubleshoot IPsec with pre-shared key
• Implement and Troubleshoot IPv6 First Hop Security

Alright here is where things start to get interesting. For the most part these subjects make sense and don’t seem “crazy”. But, things like IPsec/DMVPN and IPv6 First Hop Security are going to raise some eyebrows. I cannot agree more with putting in DMVPN/IPSEC. For one thing it’s relevant and in almost all my clients networks. Second with Cisco pitching iWAN as transport independent (DMVPN), intelligent path control (PfR), optimizing (WAAS), and security (CWS) you can see where this is going.
Having expert level knowledge in VPN, BDF/BGP, troubleshooting, and packet capture interpretation is only going to make you a better engineer in the long run.

Finally, and I saved the best for last. The format of the lab. Please don’t shoot the messenger, but keep in mind that the CCIE is the most prestigious certification in our industry. It’s the top of the summit, the best of the best, unrivaled, CCIE is the #1. https://www.youtube.com/watch?v=B-7foxHfhE4

In order to maintain that level of prestige the certification program for CCIE has to continue to evolve and mature. I remember thinking of quitting when v3 changed to v4, but then I pressed on and I’m so happy that I did because it was the hardest I have done from an education perspective, but it’s also the most rewarding.

OK, enough stalling. Here is the skinny. The lab format will consists of the following modules.

1: Troubleshooting (TS)
2: Diagnostic (DIAG)
3: Configuration (CFG)

CFG and TS are using virtual devices (IOU). This is nothing new for v4 TS, but for CFG this is new. The content delivery system will be similar to the web-based system for v4. My thoughts are that since the v4 TS supported large topologies, you may see this on v5 CFG now. More realistic, but also more overwhelming in my opinion. DIAG has no devices and I’ll get more into this later.

Here is the flow: TS(2hrs/variable) > DIAG (30 min/fixed) > CFG (5.5 hours/variable)

Now here is the cool part. Your TS section will allow up to 2.5 hours, but the extra 30 minutes will be deducted from the CFG section. If you spend less time on TS, you get that time in CFG. Pretty awesome as I always needed more time on TS myself.

2014-03-03 03.16.14 pm

Let’s talk turkey on this DIAG section as I’m sure many of you are curious like I was. “No devices” what gives man?

From Cisco directly…

“A new exam module called “diagnostic module” has been added and will focus on the skills required to properly diagnose network issues. The time for this new lab module is fixed to 30 minutes, no more or no less.”

Use this link for all the details on the DIAG module, but here is my summary. It’s a multiple-choice (drag and drop as well) section that will test your troubleshooting and analytic skills. It’s not open-ended questions (praise the Lord!!!), so there will be the “RIGHT” answers. Perhaps this is CEQ vs. OEQ on v4.
I’m not going to embellish here, this would be my biggest point of contention if I was taking the v5 lab for the same reasons I had with OEQ on v4. They are already testing you on theory (written) and troubleshooting (TS section), is this really necessary as it will be weighted on the overall grade. If you do terrible on this section, but passed TS and CFG you will not pass the lab. It’s extra stress that I don’t feel is necessary. Just my 2c that’s all. All that said, just like when I took the v4 and it had OEQ, you want to be the best? SUCK IT UP and DO IT!

2014-03-03 03.15.42 pm

Were almost at the home stretch. Let me summarize a few key things here.

The exam should be the ROUTING and switching exam because clearly L2 technologies are not as prevalent as L3. Perhaps moving CFG to IOU has something to do with it, but it’s clear that your going to want to really study up on L3 this time around. It’s nice from a focus perspective. Here is the breakdown which is awesome.

2014-03-03 03.23.36 pm
Exam Number: The exam number has changed from 350-001 to 400-101 and the written format is the same as v4.

Lab Gear: The recommendation for lab gear is ISR G2 2900 w/ 15.3T and 3560x with 15.0SE (IP Services). I don’t have a handle on how many are required. I think this may be a challenge because they are able to create large CFG topologies in IOU. Perhaps VIRL when it comes out.

Lab Dates: The CCIE Routing and Switching (R&S) Written and Lab exams are being revised from v4.0 to v5.0. The last day to test for both the Written and Lab v4.0 exams will be June 3, 2014. The CCIE R&S Written and Lab exams v5.0 will be available for testing on June 4, 2014.

Words of Encouragement: Sure things have changed and some of these changes are overwhelming right now, but I love the fact that routing is back in vogue and they removed some of the older “noise” from the exams. I never agreed with PfR on the CFG section and absolutely hated ZBF on v4 lab. GOOD RIDDANCE! INE and IPexpert already seemed to have good materiel in the works for v5 and #CLUS 2014 will have some practice labs for v5. Obtaining the CCIE is and always will be the pinnacle of my career certification goals. While the road was challenging and a little bumpy, I would not have it any other way. In fact, I’m gearing up for #2 with Data Center later this year.

If it was easy, everyone would be a CCIE. Just keep that in mind as you embark on your own journey and NEVER GIVE UP!

I leave you with a song I think was made for CCIE’s in training. ENJOY!

“It’s gonna take time, a whole lot of precious time, it’s going to take patience and time to do it right child.”
“It’s gonna take money, a whole lot of spending money, it’s going to take plenty of money, to do it right”
“And this time I know it’s for real, The feelings that I feel, I know if I put my mind to it, I know that I really can do it”

-George Harrison
Song: I got my mind set on you 

Man, that song was really made for CCIE candidates!

alright
