Palo Alto NGFW lab 2 of 30

Configuration management: commit, revert, snapshots and rollback

Work safely with PAN-OS configurations: candidate versus running, previewing and reverting changes, commit descriptions, named snapshots, reading commit and validation errors, rolling back, and checking software, content and licence status.

Run this lab

It needs Lite: its 2 nodes are set to 3 vCPU and 6,656 MB in total. That fits the free demo too.

In your workspace: Shared, then Palo Alto NGFW PAN-OS 11 guided labs, then 02 - Configuration management - commit revert snapshots and rollback

The scenario

The Leeds depot firewall is in production. A colleague built its interfaces, zones, two security rules and an outbound NAT rule. A request has come in to add an address object for a new depot printer. Before you touch a live firewall, you'll practise the safety net:

  • save a snapshot;
  • preview and undo changes;
  • commit with a reference;
  • recover from mistakes;
  • roll back when a change turns out to be wrong.

FW1management 10.1.1.254 (web and SSH from Client-PC), consoleadmin / Lab-Access-1
Client-PC10.1.1.10, desktop with Firefoxopens directly

Before you start. Start all the nodes. The firewall takes 6-8 minutes to boot and comes up with this lab's starting configuration already loaded. Wait until the FW1 console shows FW1 login:, then log in as admin / Lab-Access-1. Until the management plane is ready it answers Login incorrect, even with the right password. The Linux hosts are ready within seconds.

What you’ll practise

  • Save a named configuration snapshot before a change
  • Preview the difference between candidate and running configuration, then revert it
  • Commit with a description and find the change in the configuration log
  • Read and fix a commit validation error
  • Roll back to a saved snapshot
  • Find the software, content and licence status of the firewall

The tasks

  1. Save a named snapshot before you change anything
  2. Make a change, preview it, then revert it
  3. Commit a change with a description
  4. Read and fix commit errors
  5. Roll back to the snapshot
  6. Software, content and licence status

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 Palo Alto NGFW PAN-OS 11 guided labs.

  3. Open 02 - Configuration management - commit revert snapshots and rollback 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.
