What’s Changed in Release 22.1R1

Junos OS API and Scripting

  • The <request-system-zeroize> RPC response indicates when the device successfully initiates the requested operation (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—When the <request-system-zeroize> RPC successfully initiates the zeroize operation, the device emits the <system-zeroize-status>zeroizing re0</system-zeroize-status> response tag to indicate that the process has started. If the device fails to initiate the zeroize operation, the device does not emit the <system-zeroize-status> response tag.

Network Management and Monitoring

  • Junos XML protocol Perl modules deprecated (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—We no longer provide the Junos XML protocol Perl client for download. To use Perl to manage Junos devices, use the NETCONF Perl library instead.

    [See Understanding the NETCONF Perl Client and Sample Scripts.]

  • Changes when deactivating or deleting instances of the ephemeral configuration database (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—The following changes apply when you deactivate or delete ephemeral database instances in the static configuration database:
    • When you deactivate the entire [edit system configuration-database ephemeral] hierarchy level, the device deletes the files and corresponding configuration data for all user-defined ephemeral instances. In earlier releases, the files and configuration data are preserved; however, the configuration data is not merged with the static configuration database.

    • When you delete an ephemeral instance in the static configuration database, the instance's configuration files are also deleted. In earlier releases, the configuration files are preserved.

    • You can delete the files and corresponding configuration data for the default ephemeral database instance by configuring the delete-ephemeral-default statement in conjunction with the ignore-ephemeral-default statement at the [edit system configuration-database ephemeral] hierarchy level.

    [See Enable and Configure Instances of the Ephemeral Configuration Database.]

  • Support for automatically synchronizing an ephemeral instance configuration upon committing the instance (EX Series, MX Series, MX Series Virtual Chassis, PTX Series, QFX Series, and vMX)—You can configure an ephemeral database instance to synchronize its configuration to the other Routing Engine every time you commit the ephemeral instance on a dual Routing Engine device or an MX Series Virtual Chassis. To automatically synchronize the instance when you commit it, include the synchronize statement at the [edit system commit] hierarchy level in the ephemeral instance's configuration.

    [See Commit and Synchronize Ephemeral Configuration Data Using the NETCONF or Junos XML Protocol.]

User Interface and Configuration

  • Load JSON configuration data with unordered list entries (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—The Junos schema requires that list keys precede any other siblings within a list entry and appear in the order specified by the schema. Junos devices provide two options to load JSON configuration data that contains unordered list entries:

    • Use the request system convert-json-configuration operational mode command to produce JSON configuration data with ordered list entries before loading the data on the device.

    • Configure the reorder-list-keys statement at the [edit system configuration input format json] hierarchy level. After you configure the statement, you can load JSON configuration data with unordered list entries, and the device reorders the list keys as required by the Junos schema during the load operation.

    When you configure the reorder-list-keys statement, the load operation can take significantly longer to parse the configuration, depending on the size of the configuration and number of lists. Therefore, for large configurations or configurations with many lists, we recommend using the request system convert-json-configuration command instead of the reorder-list-keys statement.

    [See json and request system convert-json-configuration.]
