What to know about Install, Initial Configuration, and Upgrade
Be able to run the Setup Utility end to end: license the device, provision modules, set management networking, NTP, DNS, and a device certificate, then upgrade TMOS. The single most important thing is that a valid license must be activated before any module can be provisioned.
Initial configuration via the Configuration Utility Setup Utility, including management interface, hostname, and root/admin credentials
License activation and dossier generation, and the requirement that a valid license exist before provisioning modules
Module provisioning with tmsh or the Configuration Utility after licensing, such as LTM, ASM, and APM
Upgrade workflow using the Software Management screens or tmsh install, plus reactivation and validation on a non-production device
Watch out for
Common Install, Initial Configuration, and Upgrade exam traps
- ▸Assuming modules like LTM or ASM can be provisioned before a valid license is activated; provisioning is blocked until licensing succeeds.
- ▸Treating initial configuration as complete without setting NTP, DNS, and a self-issued device certificate, which affects later trust and sync.
- ▸Upgrading the production unit directly instead of validating the new TMOS version on a test or standby device first.
