Install the Device Certificate for a Managed Firewall

1. Log in to the Panorama Web Interface as a Superuser.
   A Panorama admin with Superuser access privileges is required to generate OTP Request Token and apply the OTP used to install the device certificate on a managed firewall.
2. (Best Practices) Configure the Network Time Protocol (NTP) server for Panorama.
   An NTP server is required validate the device certification expiration date, ensure the device certificate does not expire early or become invalid.
   1. Select PanoramaSetupServices.
   2. Select NTP and enter the hostname or IP address of the Primary NTP Server.
   3. (Optional) Enter a the hostname or IP address of the Secondary NTP Server.
   4. (Optional) To authenticate time updates from the NTP server(s), for Authentication Type, select one of the following for each server.
      • None (default)—Disables NTP authentication.
      • Symmetric Key—Firewall uses symmetric key exchange (shared secrets) to authenticate time updates.
        • Key ID—Enter the Key ID (1-65534)
        • Algorithm—Select the algorithm to use in NTP authentication (MDS or SHA1)
   5. Click OK to save your configuration changes.
   6. Select Commit and Commit to Panorama.
3. Configure the Network Time Protocol (NTP) server.
   An NTP server is required validate the device certification expiration date, ensure the device certificate does not expire early or become invalid.
   1. Select DeviceSetupServices and select the Template.
   2. Select one of the following depending on your platform:
      • For multi-virtual system platforms, select Global and edit the Services section.
      • For single virtual system platforms, edit the Services section.
   3. Select NTP and enter the hostname or IP address of the Primary NTP Server.
   4. (Optional) Enter a the hostname or IP address of the Secondary NTP Server.
   5. (Optional) To authenticate time updates from the NTP server(s), for Authentication Type, select one of the following for each server.
      • None (default)—Disables NTP authentication.
      • Symmetric Key—Firewall uses symmetric key exchange (shared secrets) to authenticate time updates.
        • Key ID—Enter the Key ID (1-65534)
        • Algorithm—Select the algorithm to use in NTP authentication (MDS or SHA1)
   6. Click OK to save your configuration changes.
   7. Select Commit and Commit and Push your configuration changes to your managed firewalls.
4. Generate the OTP Request Token on Panorama.
   The OTP Request Token generated on Panorama is used to generate the OTP required to install the device certificate on a managed firewall.
   1. Select PanoramaManaged DevicesSummary.
   2. Select one or more managed firewalls.
   3. Select Request OTP From CSPCustom selected devices.
   4. Copy the entire output in the OTP Request Token field.
5. Generate the One Time Password (OTP) for managed firewalls.
   OTP lifetime is 60 minutes and expires if not used within the 60 minute lifetime.

   Firewall may only attempt to retrieve the OTP from the CSP one time. If the firewall fails for any reason to fetch the OTP, the OTP expires and you must generate a new OTP.
   1. Log in to the Customer Support Portal with a user role that has permission to generate an OTP.
   2. Select ProductsDevice Certificates and Generate OTP.
   3. For the Device Type, select Generate OTP for Panorama managed firewalls and click Next.
   4. Paste the OTP request you copied in the previous step and Generate OTP.
   5. Click Done and wait a few minutes for the OTP to successfully generate.
   6. View OTP History.
   7. In the Current One Time Password History, copy or download the OTP
   8. Copy to Clipboard or Download the OTP.

6. Install the device certificate on managed firewalls.
   Managed firewalls must have an outbound internet connection to successfully install the device certificate. After you upload the OTP from Panorama, each managed firewall connects to the Palo Alto Networks CSP to install the device certificate.
   1. Log in to the Panorama web interface as a Superuser user.
   2. Select PanoramaManaged DevicesSummary and Upload OTP.
   3. Paste the OTP you generated and Upload.
      You must still copy and paste the OTP generated from the Palo Alto Networks CSP even if you downloaded the OTP in the previous step. Uploading the file containing the OTP is not supported.
7. (WildFire and Advanced WildFire) Log in to the firewall CLI and refresh the firewall settings to establish a connection to the Advanced WildFire cloud with the updated device certificate.
   Repeat this step for each managed firewall with an activate WildFire or Advanced WildFire subscription that is actively communicating with the Advanced WildFire cloud service.
