What’s Changed

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

General Routing

  • Verified the qualification of ordered-by-user in the hierarchies (ACX Series, EX Series, MX Series, QFX Series, SRX Series, vMX, and vSRX)—The requested hierarchies are reviewed and checked to confirm if they qualify for the ordered-by-user list type. If they do not, the flag autosort is included in the DDL definition for the list, making it ordered-by-system. The hierarchies are now indexed. The benefits from this arrangement are we get accurate data modeling and optimized configuration load in the user interface infrastructure.

  • In the past inet6flow.0 was not allowed to be a primary rib in a rib-group. Starting with Junos OS Release 22.3 this is now allowed.

  • Two new alarms are added and can be seen with MPC11E when 400G-ZR optics are used. High Power Optics Too Warm: warning of the increase in chassis ambient temperature with no functional action taken on the optics Temperature too high for optics power on: New inserted optics when the chassis ambient temperature is elevated beyond the threshold will not be powered on and would need to be reinserted when the ambient temperature is within the acceptable range

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).]

  • Ability to restart restart daemonized applications—Use the request extension-service restart-daemonize-app application-name command to restart a daemonized application running on a Junos device. Restarting the application can assist you with debugging and troubleshooting.

    [See request extension-service restart-daemonize-app.]

  • The xmlns:junos attribute includes the complete software version string (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—The xmlns:junos namespace string in XML RPC replies includes the complete software version release number, which is identical to the version emitted by the show version command. In earlier releases, the xmlns:junos string includes only partial software version information.

Network Management and Monitoring

  • operator login class is restricted from viewing NETCONF trace files that are no-world-readable (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—When you configure NETCONF tracing options at the [edit system services netconf traceoptions] hierarchy level and you restrict file access to the file owner by setting or omitting the no-world-readable statement (the default), users assigned to the operator login class do not have permissions to view the trace file.
