I am looking for JNCDS-SP, but it seems design exams has changed an no valid questions exist in current dumps. I took recently JNCDA an almost no questions were registered previously in any dump or any website ... 😕

[deleted] maybe not allowed ask was here.

Searching in Juniper Learning portal, I have found a practice exam: Along with a series of videos, which maybe are enough for taking the exam? I will feedback. BWT, I passed JNCDA training with the all-access video course. I not a seller from Juniper, I swear : )

Hi @starvingwage, do you have the study material of JND-SP-18a? I have all-access pass to Juniper Learning, but I see this course is instructor led, and there are no close upcoming events to schedule 😞 Is there any other way to get the material, perhaps? Thanks in advance !

Has anyone dumps for the most updated exams? I've found old versions only... JNCDA -- JN0-1102 JNCDS-SP -- JN0-1362 juan

Hi guys, anyone has taken JNCIE recently? How is is the online proctored delivery when it comes lag in keystrokes, for instance? I have seen also scripting is needed, as Python embedded modules. Is that really asked in the real lab? ([Hidden Content])

Really appreciated starvingwage, I will look for that course.

Really appreciated Kechik for your piece of advise. The PNETLAB environment works perfectly and allow things as eve-ng pro does, such as hot link connection and dockers.

Do you guys know where can I get training for this design certs.? I have available so far Juniper free training videos and testing exams. But I think it is not enough... juan

More info. Running in (RIOT) lite-mode implicitly, without configuring the "set chassis fpc 0 lite-mode", this is the consumption of the vVCP (1vCPU, 1GB vRAM), vPFE (3vCPU, 2GB vRAM):

Yes! It does work in PNETLAB by default loading the vPFE in lite-mode. This rocks! juan

Hi guys, Here you go latest vMX unlimited image from Juniper (v21.2R1.10). I will try to make it work in PNETLAB, as in eve-ng community is not possible (Ubuntu 16 opposite to Ubuntu 18). Have you guys any advise to make this work in eve-ng community version with Ubuntu 16 ¿? juan

So far, with covid-19 exceptional situation, it is possible to take online proctored lab. I hope this will be available next months too...

yes

Sorry, I mistake the topic. I haven't take the lab exam yet.

No problem. Just PM to me if some link goes down juan

Hi, Anyone else took the exam recently? I am taking it most likely next week. Thanks, juan

Really appreciated 🙂 Thanks! juan

Thanks so much, Kechik. I will investigate that tool, perhaps it is a better choice. Do you have any starting guide or web resources to get started? Thanks juan

Added chassis working mode in "lite-mode"

Hi, thank you for your information! My problem is I use eve-ng community edition, and v20 and above is not yet supported. But that's a great news as little further no longer license will be needed : )

I've managed to run 10 vMX nodes at a time. There are some considerations in order to achieve this. And of course is not perfect, for instance you can get a laggy CLI sometimes. So far I just checked every control plane and PFE is up and running and linked properly, as well as a p2p links connecting all the topology. 1. You can seize vCPU consumption "stopping" Data Plane Development Kit (DPDK) from polling constantly from VCP to VFP. This is accomplished whether running a lab or not, coz is done at Linux VM hosting eve-ng. Here you go the web site which instructs how to make the process. This is intended for JUNIPER devices, not tested with multivendor. 2. Limit CPU usage of VMWare: even though VMWare will take over all resources, you can modify settings of eve-ng VM so that it does not feed up you computer resources, thereby avoiding a bottleneck. In my case, I have 6 core and 12 threads. In eve-ng VM settings, I set 3 CPUs and 3 threads per CPU, resulting in 9 threads. This maintains my computer CPU at some 85-90% at maximun. 3. License your vMX devices and enable network-services ip. this will be need for MPLS VPNs and so on... (advances features mostly in PE nodes). I have posted in other thread a WA to install SA license in vMX v19.4 4. Getting rid of bothering syslog messages flooding all time in your console (really Telnet) terminal. This can be done following a WA posted in next website (post no. 😎 5. Set chassis in lite-mode: in order to expend less vRAM, you can set VCP to 1 vCPU and 1024MB of vRAM and VFP to 3 vCPU and 2048MB of vRAM. Boot with these settings and set the command: "set chassis fpc 0 lite-mode". Once done, reboot. After rebooting check "RIOT LITE-MODE" is on checking show chassis hardware. The essentially decrease the amount of vRAM consumed by vMX. Only drawback is links capacity lowers to 100Mbps. Still enough to make tests with a traffic generator like Ostinato (also supported in eve-ng). I will update this thread if I found more improvements. Cheers juan

I have a 6 core / 12 threads i7 @4.5GHz and 32GB of RAM.

Hi guys, Do you use vMX to make your labs? I have lot of CPU usage , even turning fpc into "lite" mode. Do you use some alternative to eve-ng? Perhaps running directly vMX as separete VMs in VMware and connecting them with virtual adapters is a better approach? Thank you for you advise juan

Hi guys, There is a bug in this vMX version which prevents temporal license installation. License is needed especially in PE nodes to configure MPLS VPNs, for instance. The workaround can be found in this link: I have successfully tested in and works. Only thing is that license is valid for 30-days trial, instead of the supposedly 60-days trial. I read upon expiration, it is only needed to "wipe" your nodes in eve-ng (that I use in my case). Trial license number is as follows: In the KB, the output shall be as follows: In the vMX in eve-ng, the output is the same, so success : )) Cheers, juan
