Nokia SR OS NRS I lab 1 of 14

SR OS CLI, classic and MD-CLI

Get around both SR OS command lines on a bench router: name it, save it, add a user, open the MD-CLI and commit a change with it.

Run this lab

It needs Lite: its 1 node is set to 2 vCPU and 4,800 MB in total. That fits the free demo too.

The scenario

Rivermark Networks is a regional carrier moving to Nokia 7750 SR routers, and you've just joined the team that runs them. A spare router is on the bench with nothing on it but the name SPARE. Before anyone lets you near the live network, you want to be at home on its command lines.

SR OS has two of them. The classic CLI has been around for twenty years and is what most of the field still types. The MD-CLI is the newer, model-driven one, and later releases default to it. You'll use both, so this lab starts with the classic CLI, then opens the door to the MD-CLI and makes a real change with it.

What you’ll practise

  • Read the version, chassis and licence of an SR OS router
  • Navigate the classic configuration tree and use info, pwc and pipes
  • Save the configuration and explain the star in the prompt
  • Create a local user with console access
  • Allow both CLI engines and switch between them
  • Set mixed configuration mode and commit a change from a private candidate

The tasks

  1. Read the router
  2. Move around the classic tree
  3. Name the router and save it
  4. Add an operator account
  5. Open the MD-CLI
  6. Change something with commit

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 Nokia SR OS NRS I guided labs.

  3. Open 01 - SR OS CLI classic and MD-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.
