JNCIA-Junos lab 2 of 15

Working fast in the Junos CLI

Work fast and accurately in the Junos CLI: find any command with the help system, filter long output with pipes, move around the configuration hierarchy, and use copy, rename, deactivate and annotate to edit like an experienced engineer.

Run this lab

It needs Lite: its 1 node is set to 4 vCPU and 5,120 MB in total. That fits the free demo too.

The scenario

HQ is now built and in service. Before you change anything on a live router, you need to be quick and confident in the CLI: finding commands you have never used, cutting long output down to the line you need, and editing without retyping whole stanzas. A new depot is opening soon and will plug into the spare port ge-0/0/2.

What you’ll practise

  • Use ?, command completion, help topic, help reference and help apropos
  • Filter operational output with match, except, count, find, last, no-more and save
  • Navigate the configuration hierarchy with edit, up, top and exit, and run operational commands from configuration mode
  • View configuration in hierarchy and set formats
  • Edit efficiently with copy, rename, deactivate, annotate and delete

The tasks

  1. Find commands with the help system
  2. Filter operational output with pipes
  3. Read the configuration two ways
  4. Move around the configuration hierarchy
  5. Edit like a power user

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder JNCIA-Junos JN0-106 guided labs.

  3. Open 02 - Working fast in the Junos CLI and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
