What’s Changed

SHA-1 password format deprecated (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX and vSRX)—We've removed the sha1 option at the [edit system login password format] hierarchy level because SHA-1 is no longer supported for plain-text password encryption.

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.

Instance type change is not permitted from default to L3VRF in open configuration (ACX Series, EX Series, MX Series, QFX Series, SRX Series, vMX, and vSRX)—DEFAULT_INSTANCE is the primary instance that runs when there is no specific instance type configured in the route set routing-options. Any instance you explicitly configure is translated into set routing-instance r1 routing-options. The issue appears in translation, when you change instance type DEFAULT_INSTANCE (any instance to DEFAULT_INSTANCE) to L3VRF or L3VRF to DEFAULT_INSTANCE. As a result, such changes are not permitted. Additionally, DEFAULT_INSTANCE can only be named DEFAULT, and DEFAULT is reserved for DEFAULT_INSTANCE, therefore allowing no such changes.

DES deprecation for SNMPv3—The Data Encryption Standard (DES) privacy protocol for SNMPv3 is deprecated due to weak security and vulnerability to cryptographic attacks. For enhanced security, configure the triple Data Encryption Standard (3DES) or the Advanced Encryption Standard (CFB128-AES-128 Privacy Protocol) as the encryption algorithm for SNMPv3 users.

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.]

Changes to the NETCONF <edit-config> RPC response (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—When the <edit-config> operation returns an error, the NETCONF server does not emit a <load-error-count> element in the RPC response. In earlier releases, the <edit-config> RPC response includes the <load-error-count> element when the operation fails.

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.

• 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.
