Interfaces

  • Support for port bounce (EX Series, MX Series, QFX Series, and PTX Series)—Starting in Junos OS Release 23.4R1, you can shut down the interface for a given time by using the request interface bounce interface_name interval seconds. The interface goes up at the end of the configured time.

    [See request interface bounce.]

  • Support for VXLAN on flexible tunnel interfaces (SRX Series and vSRX) —Starting in Junos OS Release 23.4R1, we support VXLAN on flexible tunnel interface (FTI) on Juniper Networks® SRX Series Firewalls (SRX series). To configure FTIs on your device, use the vxlan-gpe parameter under the tunnel-endpoint VXLAN encapsulation at the [edit interfaces interface-name unit logical-unit-number tunnel encapsulation] hierarchy level. When you configure an FTI on SRX series devices, you must also configure the following:

    • A security zone for the FTI.

    • The security policy with security rules for traffic sent to the FTI.

    For more information, see Flexible Tunnel Interfaces Overview and Configuring Flexible Tunnel Interface on an SRX.

  • QDD-400-ZR and JCO400-QDD-ZR DWDM optics support (MX960 with MPC10E-10C-MRATE, MPC10E-15C-MRATE line cards)—Starting in Junos OS Release 23.4R1, we support QDD-400-ZR and JCO400-QDD-ZR Dense Wavelength Division Multiplexing (DWDM) optics. You can configure wavelength option at the set interfaces interface-name optics-options hierarchy level. We support the following features:

    • Flex grid channel spacing in increments of 6.25 GHz.

    • 75 GHz or 100 GHz frequency spacing.

    • Performance monitoring and threshold-crossing alert (TCA). You can manage optical transport link efficiently. You can view the current and historical performance monitoring metrics, which are accumulated into 15-minute and 1-day interval bins, by using the show interfaces transport pm command. TCAs provide the management system an early indication of the deteriorating health of an optical network connection when the performance parameter that you monitor crosses a certain threshold.
