What's Changed

Learn about what changed in this release for QFX Series Switches.

General Routing

  • SSH key options for user account credentials. You can configure key-options <key-options> option at the set system login user user authentication ssh-rsa|ssh-ecdsa|ssh-ed25519 <ssh key> hierarchy level.

    [See login.]

  • Changes to show system alarms command output (QFX5130 and QFX5220)—When the current version of the firmware is less than the minimum supported version, you can now see alarms for this mismatch in the output of the command. These alarms were not shown previously. For example, when you have a firmware version mismatch, you should now see output similar to the following:

  • Option allow-transients is set by default for the EZ-LAG commit script—The EZ-LAG feature simplifies setting up EVPN multihoming configurations using a set of configuration statements and a commit script. The commit script applies transient configuration changes, which requires the allow-transients system commit scripts option to be set. Now the default system configuration sets the allow-transients option at the EZ-LAG commit script file level, removing the need to set this option manually. In earlier releases where this option isn't set by default, you must still configure the option explicitly either globally or only for the EZ-LAG commit script.

    [See Easy EVPN LAG Configuration Overview.]

  • Deprecation of jnxLEDTable—The jnxLEDTable table is no longer supported

  • Reset high-power optics(QFX5130-32CD, QFX5130-48C, QFX5130-48CM, QFX5220-32CD, QFX5220-128C, QFX5230, and QFX5240)—Junos OS automatically shuts down high-power optics upon Fire Shutdown threshold breach. Use the request interface optics-reset command to re-enable normal operation.

    [See request interface optics-reset.]

EVPN

  • Duplicate MAC detection timeout (QFX5000 Series switches and EX4650 switches)—The default setting for auto-recovery-time is 5 minutes on these platforms only.

    [See duplicate-mac-detection.]

User Interface and Configuration

  • Access privileges for request support information command (ACX Series, EX Series, MX Series, QFX Series, SRX Series Firewalls, and vSRX Virtual Firewall)— The request support information command is designed to generate system information for troubleshooting and debugging purposes. Users with the specific access privileges maintenance, view, and view-configuration can execute request support information command.

  • Changes to the show system storage command output (ACX Series, EX Series, MX Series, QFX Series, and SRX Series)—We've updated the show system storage command output to include only true (physical) storage and exclude any host/hypervisor level storage. In earlier releases, the output also includes a container/jail storage, which does not have a separate storage of its own.
