Beginning with PAN-OS 10.1 and later releases, we support Username/password and
                Satellite Cookie Authentication method for a satellite to authenticate to the
                portal. This method requires user intervention to get satellites authenticated by a
                portal that prevents automating the deployment of remote satellites and adds
                difficulty and complexity for the administrators to perform software upgrade and
                deploy new firewalls. 
To remove the user intervention while onboarding a remote satellite and to
                enable automating the deployment of remote satellites, we introduce a new
                authentication method called 
Serial number and IP address
                        Authentication. You can now onboard a remote satellite using the
                combination of serial number and IP address in addition to the username/password and
                satellite cookie authentication method. This authentication method reduces the
                complexity by enabling you to deploy new firewalls without manual intervention. 
However, Username/password and Satellite Cookie Authentication remains as a default
                authentication method. 
Before enabling the Serial number and IP address Authentication method, configure the
                satellite serial number at the portal as one of the authentication verification
                conditions.
- Configure the satellite IP address as an IP allow list at the portal
                    using the set global-protect global-protect-portal portal
                            <portal_name> satellite-serialnumberip-auth
                        satellite-ip-allowlist entry <value>
                    command to add a satellite device IP address on the GlobalProtect portal.
- Enable the Serial number and IP address Authentication method using the
                        set global-protect satellite-serialnumberip-auth
                        enable CLI command. After you enable this method, the satellite
                    continuously attempts to authenticate with the portal for the configured retry
                    interval (in seconds) after power-on until the portal explicitly instructs the
                    satellite to stop.
Upon successfully configuring a satellite device allowed IP address list per portal,
                and configuring the satellite serial number on the GlobalProtect portal, the
                satellite can initiate the connection to the portal.
