Software Installation and Upgrade

  • Phone-home client (vSRX)—Starting in Junos OS Release 21.1R1, the phone-home client (PHC) is responsible for the initial bootup and configuration of the vSRX VM instance when the virtual machine (VM) instance is turned on. When the vSRX VM instance boots up with the factory-default configuration, the phone-home client connects to a redirect server, which then redirects to the phone-home serverr. The phone-home client downloads the initial configuration and the latest Junos OS image from the phone-home server. .The new image is installed first, and then the initial configuration is applied and committed on the vSRX VM instance.

    If the redirect server does not provide any phone-home server information, the phone-home client restarts the provisioning process and keeps connecting to the redirect server until provisioning is successful.
