Software Installation and Upgrade

  • ZTP on WAN Interfaces (ACX7100-32C, ACX7100-48L, and ACX7509) — Zero-touch provisioning (ZTP) dynamically detects the port speed of WAN interfaces and uses this information to create ZTP client ports with the same speed. ZTP automatically cycles through the WAN ports until it receives DHCP options from the DHCP server. The device uses the DHCP options to perform the bootstrap process.

    [See Zero Touch Provisioning.]

  • Separate firmware installation packages (ACX7024, ACX7024X, ACX7100, ACX7332, ACX7348, PTX10004, PTX10008, and PTX10016)—You can manage firmware upgrades using standalone firmware installation packages. The names for these packages begin with the prefix jfirmware-junos-evo-install*. You can use these packages to upgrade firmware independently from full software upgrades, addressing requirements such as bug fixes, security updates, and new functionality from hardware vendors. The firmware packages align with the naming conventions of EVO packages and are version-independent, allowing for targeted updates without needing to upgrade all of the software on a system.

    You add a firmware package to the system with the request system software add command. Once you have added the firmware package to your system, you update the firmware for a hardware component using the request system firmware upgrade command.

  • Static configuration of MAC-IP bindings (ACX7100-32C, ACX7100-48L, PTX10001-36MR, and PTX10008)—You can configure MAC-IP bindings on interfaces to improve network management and host communication. This setup is similar to configuring static MAC addresses on an interface. Use this feature to streamline operations in static environments, such as Internet Exchange Points (IXPs), where Customer Edge (CE) routers remain fixed.
