Common maintenance and upgrade tasks can’t be overlooked. In this section, we demonstrate how to perform common maintenance tasks on the Palo Alto firewalls. We perform PAN-OS software upgrades. We also look at configuration management on the firewall. We perform tasks right from performing configuration change revisions, backup configs, restore configs, to finally reverts. Also, we shall demonstrate an emergency firewall recovery procedure, using the firewall console interface. We will also take a peek into Palo Alto’s centralized management platform: Panorama.
