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.

General Routing

  • The max-db-size is an optional configuration command on routers having >=32 GB DRAM, for example, on MX960 platform. To enable subscriber-management, use the command set chassis network-services enhanced-ip and set system services subscriber-management enable. The router reboots and comes-up with subscriber-management enabled without max-db-size (optional) configuration and requires only 1 reboot.

  • 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.

  • 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.]

  • NOTE: In the CLI using the command request chassis feb slot slot-number offline if you make the primary FEB offline, a traffic loss warning message is displayed and the FEB offline request is rejected. If offline/restart is still intended for primary FEB, use force option in addition to the command. WARNING message displayed in the CLI: "warning: RCB and FEB work in the paired slot mode. FEB %s offline/restart will result in traffic loss and does not cause a switchover. Please re-try after initiating a mastership switchover using 'request chassis routing-engine master switch' CLI. If offline/restart is still intended, use 'force' option in addition to this CLI."

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).]

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, vMX, 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.
