It’s rumored that the announcement for the R&S CCIE v5 update should be coming soon (November timeframe) and the switch over for the lab sometime around March 2014. Cisco Live Europe has a R&S v5 Technical Breakout scheduled for anyone attending. The update to version 5 is rumored to be a 100% virtual lab environment similar to how the troubleshooting section of the lab is done now. The major benefit of the lab going virtual is that the topics covered will be platform independent. You will not need to buy 2911′s or 3750x’s to prepare and can use any relatively newer router or switch to prepare or use a virtualized environment (IOL/IOU/VIRL, GNS3, CSR). The goal of the v5 appears to be to focus on the technologies themselves and less on the hardware and a specific topology. This is the best move Cisco has made for the R&S CCIE program in years as candidates will need to focus more on the technologies themselves and not worry about IOS versions, hardware platforms, physical topologies, etc.

Allegedly the R&S CCIE v5 blueprint will see legacy topics like Frame-Relay removed. Additionally it’s possible some of the more lesser used features of the IOS like Zone-Based Firewall, WCCP, IPv6 multicast, and PfR could be removed from the lab. A few of the topics we could see added are IPSec, DMVPN, and Embedded Packet Capture. We may see ISIS added to the written at least if not the lab. This could be the last version of the R&S lab that isn’t IOS XE based so we could see it added to the written.

Currently the lab has a 2 hour troubleshooting section and a 6 hour configuration section. The new lab may contain, in addition to the troubleshooting section, a new diagnostic section. This means the lab could have a troubleshooting, diagnostic and configuration section. I would assume the points for this new section would come from the configuration section and the troubleshooting section would remain the same or possibly even slightly higher in points.

So what does this mean for someone currently preparing for the R&S v4 blueprint? If you feel you are close to taking the lab but do not have to scheduled, you should schedule a date ASAP. Once the official v5 announcement comes out from Cisco, it will be hard to schedule a lab date. If you have a date scheduled before March 2014 then you should be fine. If your date is after February 2014 then I would recommend you move it up ASAP. The longer we go into November the more likely the new blueprint date has been pushed back by Cisco.

Additional v4 bootcamps will be added to the schedule before the March 2014 changeover. We will start transitioning the current bootcamps over to version 5 around the first of the year. For the self-paced products we will start releasing labs and videos covering the new blueprint in November. 90% of the material from the version 4 blueprint will carry over to the version 5 lab blueprint. Topics you can skip for the routers will be Frame-Relay, PfR, WCCP, Zone-Based Firewall along with technologies that are not supported in IOU L2/IOL L2. Here is a list of features we may not see for the layer 2 section since the switches will be virtual.

1) QinQ Tunneling
2) ISL trunks
3) DHCP Snooping
4) Layer 3 Port Channel
5) Private VLANs
6) SPAN/RSPAN/ERSPAN

Post any questions you have about the new blueprint changes and I’ll start creating a FAQ below:

Q) I purchased the version 4 self-paced material so will I be covered for the version 5 products?
A) Yes.

Q) Will I have to pay anything for get the new version 5 material?
A) No.

Q) I attended an R&S CCIE v4 bootcamp so can I resit a v5 bootcamp for free?
A) Yes.

Q) Will INE offer racks for the new blueprint?
A) Yes. Although the lab is virtual it is still good to spend part of your preparation using real hardware as that is what you use in your day-to-day job. Towards the end of your preparation you can hone your skills using virtualized environment. We will be using the CSR along with real switches for the virtualized environments.

Q) What about my tokens?
A) Your tokens will carry over.

Q) I’m currently schedule for the lab after the v5 update. Can I still take the v4 lab?
A) No.

Q) Do you feel strongly that the announcement will come out in November?
A) I do feel confident that the announcement will be in November but it could slip since they are trying to align the Cisco 360 update to the lab release.

I hope everyone enjoyed the IPv4 Route Redistribution session on Friday. The turnout was amazing to say the least. We got off to a late start due to needing to split the streams between servers as we had over 2000 people logged in accessing the session. Once we got rolling you can really see how excited I get working on routers ;-) In fact I’ll be doing a few of these R&S CCIE sessions a month going forward since the turnout is so good and I really enjoying do this. The flow for these new online sessions will be that I run every session twice to get enough video for a complete product. After that it’ll take about one or two weeks to get the final product through editing and into your members site depending on the length of the session. These videos will be free for any AAP member or R&S CCIE Bootcamp customer.

I’m going to be running the IPv4 Route Redistribution session again sometime after next week and span it over two days (6 hours each). I’ll publish labs for this next session so after you watch the videos you can go back and reinforce the concepts by doing the labs. Additionally I’ll publish the initial and final configurations for the video sessions along with the configurations I capture during each of the breaks. After that I’ll go through the videos and get the complete product released.

The next sessions will be MPLS L3 VPNs and IPv4 Multicast. Both of these will be ran twice with the first session being one day in length and the second two days. Also I’ll be fitting in a few smaller sessions in between covering other topics.

As a side note the R&S CCIE Version 5 update is just around the corner. The word is that we are looking at a April/May timeframe so I’ll try and get all of the R&S topics covered in these sessions by the end of January or mid-February. Most of the sessions will carry over to the R&S CCIE Version 5 blueprint if you aren’t planning on taking the R&S CCIE Version 4 lab.

The R&S CCIE Volume 2 workbook has been ported to our new web format (see below). This format allows you to add bookmarks, add notes (both private and public notes) and ensures you always have the latest version. Additionally you can submit feedback directly to the Development and Editing teams from within workbook. We are also working on integrating our IEOC forum directly into the workbook and plan on having it available late October.

For the notes, we are currently implementing a rating system that will allow you to rate a public note posted by someone else. This will allow you to filter public notes that are not above a certain rating if desired. This new public notes feature will be really popular based on the feedback we have received from the beta testers. The R&S Volume 2 in the new web format will be released next week.

R&S Volume 3 workbook has been updated. This updated version will be available later this week in your members site account. This is the last major update to Volume 3 before it is retired and integrated into the new single R&Sv5 blueprint based workbook we are already developing.

FAQ:
Q – Will I automatically get the new workbook when its released next week if I have the current workbook?
A – Yes. The workbook will automatically show up in your members site account next week.

Q – Will I be able to view it offline?
A – Yes. A PDF version will automatically be generated when a change is made to the workbook.

Q – Can I view it on my tablet?
A – Yes the new format is pure HTML5 which is support by all modern tablet web browsers. This is the first step before we release it as an iPad/iPhone app and Android app. The tablet app will allow you to take the workbooks “offline” and still make notes, bookmarks, etc that will sync up when you get back online.

Q – Does this include new material?
A – We had to freeze any development while the workbook was ported to the web. Now that the workbook is up we’ll start adding new content. We have 3 additional labs to add to the workbook now.

Lastly Volume I is currently being ported to the web and I’ll release it in chunks as each section is finished. Currently the IP Routing section has been ported. I’m reviewing it before release and adding more PfR/OER labs.

This evening it’s topping 100 degrees in Reno, NV where our rack rental equipment is located. I’m looking at the temperature in our new data center to see how it’s holding up in regards to the high exterior temperature. We have temperature sensors for each cage in our existing data center but so far only have a few installed in our new data center. I’m looking to see what the temperature is in a couple new cages in the new data center that don’t have a temperature senor installed yet. So how can we get the temperature without a dedicated senor and only Cisco devices installed?

Relatively newer Cisco hardware has the ability to display the numerical temperature values by using the show environment command along with polling via SNMP. For the ISR G1′s (1800, 2800, 3800) the internal-ambient, CPU, intake and backplane temperature (3845) and for the ISR G2′s (1900, 2900, 3900) the intake left(bezel), intake left, exhaust right(bezel), exhaust right, CPU and power supply unit temperature can be displayed/polled. I wanted to see the temperature of the management access server (3825′s) located at the top of each cage. I assumed I would just login and issue the show environment command to see the values. Good idea but I don’t want to check it manually every few hours.

I could just login to SolarWinds and see the temperature but as we network engineers know, network management applications aren’t that fun to use. You buy them, install them, swear they are the best thing since sliced bread, drool over the fancy graphs and then two months later you never log back into them unless something is wrong. Plus my normal thought process is to always try and do whatever possible via the IOS as it’s the most fun.

To start I’ll display the values via the show environment command and then poll the values using the SNMP via TCLSH and finally wrap it up with an EEM applet to log the values.

Row8Cage1AS#show environment
 Redundant Power System is not present OR in standby mode.

 SYS PS1 is present.
        Type: AC

 AUX(-48V) PS1 is absent.

 Fan  1 OK
 Fan  2 OK
 Fan  3 OK

 Fan Speed Setting: Normal

 Alert settings:
 Intake temperature warning: Enabled, Threshold: 55
 Core temperature warning: Enabled, Threshold: 70 (CPU: 95)

 Board Temperature: Normal
 Internal-ambient temperature = 33, Normal
 CPU temperature = 50, Normal
 Intake temperature = 32, Normal

 Voltage 1(3300) is Normal, Current voltage = 3300 mV
 Voltage 2(5150) is Normal, Current voltage = 5153 mV
 Voltage 3(2500) is Normal, Current voltage = 2525 mV
 Voltage 4(1200) is Normal, Current voltage = 1215 mV 

 Nominal frequency

Row8Cage1AS#

Now I need to find the SNMP OID related to temperature for the platform. Note that SNMP has previous been setup on this router.

Row8Cage1AS#show snmp mib | in Temperature
ciscoEnvMonTemperatureStatusEntry.2
ciscoEnvMonTemperatureStatusEntry.3
ciscoEnvMonTemperatureStatusEntry.4
ciscoEnvMonTemperatureStatusEntry.5
ciscoEnvMonTemperatureStatusEntry.6
c3gModemTemperature
Row8Cage1AS#

I know it’s one of the ciscoEnvMonTemperatureStatusEntry values but which one? One should be the name, another should be the actual values and another should be the thresholds. Seems like Google should be used here but we know the values via the show environment command so we could poll them and see which one matches. We’ll learn more this way over using Google. We’ll start with the first one and walk down 99.

Row8Cage1AS#tclsh
Row8Cage1AS(tcl)#snmp_getbulk
usage: snmp_getbulk community_string non_repeaters max_repetitions oid [oid2 oid3 ...]
Row8Cage1AS(tcl)#
Row8Cage1AS(tcl)#snmp_getbulk XXXXXX 0 99 ciscoEnvMonTemperatureStatusEntry.2
{<obj oid='ciscoEnvMonTemperatureStatusEntry.2.1' val='Internal-ambient'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.2.2' val='CPU'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.2.3' val='Intake'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.3.1' val='33'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.3.2' val='50'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.3.3' val='32'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.4.1' val='70'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.4.2' val='95'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.4.3' val='55'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.5.1' val='0'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.5.2' val='0'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.5.3' val='0'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.6.1' val='1'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.6.2' val='1'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.6.3' val='1'/>}

Row8Cage1AS(tcl)#
Row8Cage1AS(tcl)#snmp_getbulk XXXXXX 0 3 ciscoEnvMonTemperatureStatusEntry.3
{<obj oid='ciscoEnvMonTemperatureStatusEntry.3.1' val='33'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.3.2' val='50'/>}
{<obj oid='ciscoEnvMonTemperatureStatusEntry.3.3' val='32'/>}
Row8Cage1AS(tcl)#

That was easy. The ciscoEnvMonTemperatureStatusEntry.3 is what we are looking for and ciscoEnvMonTemperatureStatusEntry.3.1 is a good value to use as it’s giving us the “internal ambient” temperature.

Row8Cage1AS(tcl)#snmp_getone
usage: snmp_getone community_string oid [oid2 oid3 ...]
Row8Cage1AS(tcl)#
Row8Cage1AS(tcl)#snmp_getone XXXXXX ciscoEnvMonTemperatureStatusEntry.3.1
{<obj oid='ciscoEnvMonTemperatureStatusEntry.3.1' val='33'/>}
Row8Cage1AS(tcl)#

Now how about having this value logged every 5 minutes so we can check back in the morning to see any changes overnight. An easy way to do this is to poll the SNMP OID using EEM and log the value returned using syslog if it’s above 1 degree which we know it will always be. This way EEM will always log the value to syslog.

Row8Cage1AS(tcl)#tclquit
Row8Cage1AS#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Row8Cage1AS(config)#event manager applet EEM_TEMP_MON
Row8Cage1AS(config-applet)#event snmp oid ciscoEnvMonTemperatureStatusEntry.3.1 get-type exact entry-op gt entry-val 1 poll-interval 300
Row8Cage1AS(config-applet)#action 1.0 syslog msg "Row8Cage1AS Temperature $_snmp_oid_val"
Row8Cage1AS(config-applet)#^Z
Row8Cage1AS#
Jun  7 06:53:42.011: %SYS-5-CONFIG_I: Configured from console by bdennis on vty0
Row8Cage1AS#
Jun  7 06:54:12.012: %HA_EM-6-LOG: EEM_TEMP_MON: Row8Cage1AS Temperature: 33

We could convert the value to fahrenheit if we wanted by using this TCL expression: set temp [expr {9.0*$_snmp_oid_val/5.0+32.0}].

Of course using a network management application or script on a server would be easier but doing it via the IOS was fun. There are a few other ways to do this via the IOS and one being SNMP MIB BULKSTAT.

Here is our updated and simplified CCIE bootcamp reseat policy:

Bootcamp Retake Policy
INE invites all students to retake a Bootcamp course for only a $500-per-week rack rental fee. Routing & Switching Bootcamps are excluded from the fee and are free of charge. How do you know whether seats are available for a Bootcamp retake? It’s simple! As long as the Bootcamp is not labeled “Sold Out” on our website, you can retake it. Unlike other training companies, we do not limit the number of seats for students retaking a course.

It really doesn’t get any better and simpler than this. For the non-R&S CCIE bootcamps if you calculate the reseat fee out the $500 is cheaper than you renting the rack yourself for a week especially for our Service Provider bootcamps and new Data Center Bootcamps.

Below are the steps needed to get the CSR1000v working in VMware Fusion on a Mac. Before we look at the steps here is the hardware and software I used:

CSR1000v

CSR1000v

Basically you need a quad core machine with a hypervisor (VMware, Virtual Box, KVM, etc). I just used VMware Fusion as it’s a commonly used hypervisor. Additionally I used two USB NICs to map to the GigabitEthernet1 and GigabitEthernet2 interfaces inside the CSR1000v. You could use any NICs or even subinterfaces if you are using Linux (Mac OS does support VLANs but I personally have not tried it with VMware Fusion). The GigabitEthernet0 is the management interface that is associated with the “Mgmt-intf” VRF so I didn’t want to use it for the internal and internet facing interfaces.

The Cloud Services Router, CSR1000v, which was first announced at Cisco Live in San Diego last year is now available for download. For those who have never heard of the CSR1000v, in a nutshell it’s an IOS XE image running in a virtualized environment (VMWare support now, Citrix XEN, Amazon, Windows Hypervisor and OpenStack in the near future). The CSR1000v is designed as a virtual router (think Quagga but IOS from Cisco) that resides on the hypervisor server as a client instance and provides any services a normal ASR1000 would provide between the other hypervisor’s client instances (Linux servers, Windows servers, etc) and the network infrastructure. This could be something as simple as basic routing or NAT all the way up to advanced technologies like MPLS VPNs or LISP. Basically anything that a real ASR1000 could provide you can do in the CSR1000v with a small exception. This early release only supports 50Mbps throughput due to licensing restrictions. This being the case the specifications from Cisco shows the CSR1000v being capable of pushing 1.17Gpbs max and 438Mbps throughput with an IMIX traffic flow. With the 50Mbps limit it means the CSR1000v at this stage would be deployed more for proof-of-concept as opposed to real production. At this time the throughput is limited by the licensing but I’m sure there are plans to allow for higher throughput licensing in the near future.

If you’re interested in a presentation from Cisco covering the CSR1000v you can view the Cisco Live session from London: Cisco’s Cloud Services Router (CSR 1000V): Extending the Enterprise Network to the Cloud (2013 London) Note that you will need to create an account if you don’t already have an account to view the session.

The beta version of lab 1 for the R&S CCIE Volume III Workbook has been released. It’s available in your members’ site account for customers with access to the workbook.

Additionally the initial configurations are available per section. This means you can load up to a particular section. For example you could load up to the BGP section or up to 4.6 where route redistribution start. Also the final configurations are available to load on the racks.

Note that the configurations are at the bottom of the drop down for the R&S rack rentals in the control panel.

Once this is finalized I’ll submit it to be automatically graded like our Troubleshooting Labs are now and also put into our new web workbook format. Lastly I’m now working on R&S Volume II Lab 1 and will work on both workbooks in parallel.

Please post any comments in regards to this lab here or email them directly to me.

If anyone has time this week and is interested in beta testing the new lab 1 from the R&S Volume III Workbook reply to this post. I would like a few more people to run through it before I release it later this week.

The new R&S Vol III labs are being updated and having VRFs, MPLS, MPLS VPNs, IPv6 OSPFv3 and EIGRP for IPv6 added. Fundamental multicast for IPv4 and IPv6 will also be included in some of the labs. The troubleshooting section has been updated. Along with the initial and final configurations, the configurations are available per section. So if you want to start at route redistribution, BGP, IPv6, etc you can load up to that point. Additionally the route redistribution is being standardized to follow the same methodology that I teach in my bootcamps. I’ve included a detailed walk-through explanation of the route redistribution solution used and why it was selected over other solutions so by the end of all of the Vol III labs you will be able to check route redistribution off your list of topics to worry about in the real lab.

Once the beta is done, grading will be added to lab 1 so you can have your lab graded. It’s going to take me about a week per lab to get these all updated along with adding in grading and finally beta tested before released. In addition to the grading, the show commands from the solutions will be available to compare with the show commands from your lab. This should be available within the next couple weeks for not just these labs but the new Troubleshooting Labs.
