  • Support for 400G ZR-M DWDM optics (PTX10003)— Starting in Junos OS Evolved Release 22.3R1, we support 400G ZR-M dense wavelength-division multiplexing (DWDM) optics. The new optics variant 400G ZR-M functions similar to the existing 400G ZR optics. The new variant enables flat architecture and simple Point to Point (PtP) DWDM systems. We support the following 400G ZR-M features:

    • Both 75-GHz and 100-GHz grid spacing.

    • Optical loopbacks. To enable optics loopback, use the existing loopback statement at the [edit interfaces optics-options] hierarchy level.

    • Performance monitoring and TCA. 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. You can thus manage the optical transport links efficiently. 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.

  • Support for interfaces channelization on 400G-ZR-M (PTX10001-36MR)—Starting in Junos OS Evolved Release 22.3R1, we support channelization of one 100GbE, three 100GbE, and four 100GbE interfaces along with the existing two 100GbE interfaces on 400G-ZR-M.

    [See Port Speed on PTX10001-36MR Router Overview.]

  • Support for 8x50G DAC optics (QFX5130-32CD and QFX5220-32CD)—Starting in Junos OS Evolved Release 22.3R1, we support 8x50G DAC 1M, 2M, 2.5M, and 3M variant optics. You can channelize every second port. Note that if you channelize one port, you must mark the next port as unused.

    [See QFX5220-32D guide.]

  • Support for hold-time option on aggregated Ethernet interfaces (PTX10001-36MR, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 22.3R1, we support the hold-time option with up and down milliseconds on aggregated Ethernet interfaces. You can specify the hold-time value to use a damp shorter interface transitions milliseconds.

    [See hold-time.]

  • Output filter for discard interface (PTX10003)—Starting in Junos OS Evolved Release 22.3R1, you can configure inet family protocol on the discard interface. Use this configuration to apply an output filter to the interface. When you apply the output filter, the action specified by the filter executes before the traffic discards.
