What's Changed

Learn about what changed in this release for MX Series routers.

Class of Service (CoS)

  • You cannot apply a classifier to a physical interface on MX Series routers. On MX Series routers, you must apply the classifier to a logical interface.

  • Changes to the XML output for CoS RPCs (MX204, MX240, MX304, MX480, MX960, MX10003, MX10004, MX10008, MX10016, MX2008, MX2010, MX2020)—We've updated the junos-rpc-class-of-service YANG module and the corresponding Junos XML RPCs to ensure that the RPC XML output conforms to the YANG schema. As a result, we changed the XML output for the following class of service (CoS) RPCs:

    • <get-cos-adjustment-control-profile-information>—The <adjustment-control-profile-name> tag is a child of the <adjustment-control-profile> element instead of a sibling.

    • <get-cos-red-information>—The <red> tag no longer emits the xmlns="m-t-mx-j-series-cosinfo-red-entry-format" namespace attribute.

    • <get-cos-slice-information>—The XML output only emits integers for parameters such as <shaping-rate>, <delay-buffer-rate>, and similar fields. The output does not include any units.

    • <get-scheduler-map-table-map-information>—The <cos-scheduler-map-table-information> tag does not emit a namespace attribute.

General Routing

  • Before this change most list were ordered by the sequence in which the user configured the list items, for example a series of static routes. After this change the list order is determined by the system with items displayed in numerical sequence rather than by the order in which the items were configured. There is no functional impact to this change.

  • Deprecated license revoke information—Starting in Junos OS Release 23.4R1, we've deprecated the show system license revoked-info command. You can use the show system license and show system license usage commands to know the license information.

  • Introduction of extensive option for IPsec security associations (MX Series, SRX Series and vSRX 3.0)—We've introduced the extensive option for the show security ipsec security-associations command. Use this option to display IPsec security associations with all the tunnel events. Use the existing detail option to display upto ten events in reverse chronological order.

    [See show security ipsec security-associations.]

  • Change in the XML tags displayed for the show virtual-network-functions command in JDM (Junos node slicing) — To align the XML tags displayed for the show virtual-network-functions "gnf-name"| display xml with the new XML validation logic, we have replaced the underscores (_) in the output with hyphens (-) as shown below:

    Old output:

    This change is applicable to any RPC that previously had underscores in the XML tag name.

Junos XML API and Scripting

  • Ability to commit extension-service file configuration when application file is unavailable—When you set the optional option at the edit system extension extension-service application file file-name hierarchy level, the operating system can commit the configuration even if the file is not available at the /var/db/scripts/jet file path.

    [See file (JET).]

  • XML output tags changed for request-commit-server-pause and request-commit-server-start (ACX Series, EX Series, MX Series, QFX Series, SRX Series, and vSRX)—We've changed the XML output for the request system commit server pause command (request-commit-server-pause RPC) and the request system commit server start command (request-commit-server-start RPC). The root element is <commit-server-operation> instead of <commit-server-information>, and the <output> tag is renamed to <message>.

Network Management and Monitoring

  • NETCONF <copy-config> operations support a file:// URI for copy to file operations (ACX Series, EX Series, MX Series, QFX Series, SRX Series, and vSRX)—The NETCONF <copy-config> operation supports using a file:// URI when <url> is the target and specifies the absolute path of a local file.

    [See <copy-config>.]

Platform and Infrastructure

  • Previously, shaping of Layer 2 pseudowires did not work on logical tunnel interfaces. This has been fixed for all platforms except QX chip-based MICs and MPCs.

User Interface and Configuration

  • Viewing files with the file compare files command requires users to have maintenance permission—The file compare files command in Junos OS and Junos OS Evolved requires a user to have a login class with maintenance permission.
