Starting to use Juniper/JUNOS

[StareX]

Painfully, .. I need a good guide or a good tutorial on Juniper switches. I want to learn more about JUNOS aswell. Anyone?

Go use the switch, use it in your home networking so you are force to work with it. Or find something you wanna do and configure the switch to match that. Or just do a video cours on a junos cert.

First of all, great choice! I love JUNOS for it's simplicity and cleverness.

 

JUNOS uses a hierarchial configuration which is very easy to get into once you understand what it's all about.

 

Some very useful fundamental stuff:

 

First of all the configuration is a hierarchy. A tree.

You enter configuration mode either by typing edit or configuration. That's if you're in the CLI.

If you logged in with root you end up in the root OS mode and you need to type cli to get into the cli first.

 

commit - There's a commit. Nothing gets actually changed in production until you commit. If you work remotely, "commit confirmed" and you get an automatic rollback in 10 minutes unless you commit again. That's for situations when you lose your legs due to a configuration error.

 

show gives you the current level and sublevels of configuration.

 

"show | compare" gives you the current level and sublevels of configuration of the candidate configuration that is different than running configuration. That is, it compares the candidate to running.

 

"show | display set" gives you the configuration of current level and sublevels in set commands so you can save parts of your configuration in a way that's easy to reapply if you need to.

 

set is something you begin with when you want to add configuration.

delete is something you begin with when you want to remove configuration.

 

edit is a command you use to hop to a sublevel of the configuration.

up is a command you use to hop to a parent level of the configuration.

top is a command you use to hop to the root of the configuration.

 

This is just to get you started in the configuration menu. I deliberately left out any of the configuration trees since I know you can read and they're not impossible to figure out just by looking.

 

Might have forgotten to mention some crucial stuff and I'm glad to help you out more if you need something in particular.

Never was a guide type of a guy so I don't know of any really good reading, sorry.

JNCIA is the entry level JUNOS certificate. That might help you find some materials if you like to read.

 

Oh, there's a whole bunch of stuff you can view outside of configuration mode. JUNOS is well equipped with all kinds of show commands. Though I'm sure you can find them on your own once you know what you need.
