Configuring the JunOS CLI (Standalone vMX)

Happy 2021!

A lot of the information came from this video by Network Direction. It also showed me how to use these virtual labs. Usually I just showed up, clicked random buttons, and moved onto local .iso because I knew how to get those started.

Use Juniper vLabs for an online lab space to work in.

Let the setup commence, click the arrow, then SSH!


Two modes: Operational, Configuration. 

In Cisco talk, it's the > prompt and the # prompt after you hit config t.

Most prevalent thought: How many Cisco configurations also work here? What context clues can I use to look around? 

Turns out, yes, you can use the ? to figure out where to go next.



The show configuration layout looks kind of like a JSON or Python file, without the double quotes.


Check out show chassis routing-engine: How much of a system's resources are being used, broken down.



The syntax error was from me pressing the spacebar after 'edit protocols' in an attempt to just get to bgp. You can do that, if you start at top:

Notice the edit banner has gone back to [edit] and then [edit protocols bgp]

After editing the name (much more involved than 'hostname R1'), we can compare the actions.



I like how it uses math symbols. Minus is like "Well, no need for you anymore huh".



Pretend you have bare-bones knowledge about CLIs for routers. You can figure out what 'hostname' means.

What would you find easier to get the understanding of: 

copy running-config startup-config (copy run start)

or

commit and-quit? 


After years of use, I would say the former. For the newcomer, it may still be the former, because context is there.

                                                set address 1.1.1.1/32


Easier to write and read. Unless you find it easier to have your subnet masks spelled out. No shaming here. You can also stick the entire command - the interface setting, the number, the IP addressing scheme family, the address itself - all on one line. That's amazing!

This was my first foray into configuring Junos routers, and it was easier and clearer than I thought. Let's try a VLAN. Today's resource comes from MustBeGeek.




I can set them on the vMX router, but I can't actually show them. Am I missing a command somewhere.




I like how if you mistype something, JunOS is quick to say "Nope. Wrong. Try again!"

A unit is a logical interface - What you need to create a VLAN!

It's time for that torrential troublemaker, DNS, using Juniper's own documentation.



It doesn't recognize some commands the documentation lists despite being in the proper drop-down. Again, it stops before I can add a space to continue the command and throws a "?"


Hey, at least that works!


When I was configuring a NAT Pool, I swear it automatically finished the 'match-direction' command in the line. Some of them do get rather lengthy.

Appreciate how it tells you, clearly, what statements you may be missing:

 ## Warning: missing mandatory statement(s): 'translation-type'


So, that's the first look at JunOS CLI! Fun, clear, can't wait to do more.

Making KPI Dashboards with PowerBI

 While this is the free tier, I cannot share or collaborate with others, nor can I publish content to other people's workspaces, but they will not stop me from screenshooting and recording these self-taught adventures,so! I'm doing this because I idly searched "Mattel careers" and "Information Technology", and seeing a bulletpoint saying the following: Analytical and reporting skills such as creating dashboards and establishing KPIs such as experience with PowerBI, Cognos, Tableau, and Google Data Lake/AWS is preferred And thought "Well, I've used Tableau, and I've heard about PowerBI,  even if its in-demandness is questionable , so how similar is it? And can I write about it?"  First, PowerBI (PIB) does have a downloadable, local version, but apparently Windows-only. I could download the .exe but I couldn't run it / drag it to applications on my MacBook.  Not a problem, we'll use the online SaaS version, and a dataset found here, ...

Log Sorting with AWS CloudWatch, AWS CloudWatch Insights

 The cool thing is, I was contracted to make these videos in collaboration with CloudAvail Technology Consulting to help people decide which service they wanted to use for their logging - AWS CloudWatch, AWS CloudWatch Insights, DataDog, or New Relic. I'm searching through nginx logs. I have accompanying videos of each service that you can find on the CloudAvail Youtube page; See these links to go to the DataDog and NewRelic posts.   The idea was to be subjective in the videos, but I can be objective on my personal blog.     CloudWatch     The syntax is odd, but easy to grasp. Sort log data by IP addresses, message codes, and status codes. The simplest query system, but not quite robust.   Insights       The syntax has changed - Vastly. I see major SQL influences. You can see that in how the parse function works - in this case, it's often taken pieces of a pre-existing standard - in this case, message - and breaking them into their own c...

Connecting IoT Devices to a Registration Server (Packet Tracer, Cisco)

 If you're seeing this post, I'm helping you, and you probably have LI presence: React and share this post to help me in return.   In Packet Tracer, a demo software made by Cisco Systems. It certainly has changed a lot since 2016. It's almost an Olympic feat to even get started with it now, but it does look snazzy. This is for the new CCNA, that integrates, among other things, IoT and Automation, which I've worked on here before. Instructions here . I don't know if this is an aspect of "Let's make sure people are paying attention and not simply following blindly", or an oversight - The instructions indicate a Meraki Server, when a regular one is the working option here. I have to enable the IoT service on this server. Also, we assign the server an IPv4 address from a DHCP pool instead of giving it a static one. For something that handles our IoT business, perhaps that's safer; Getting a new IPv4 address every week or so is a minimal step against an...
