  • Optics EM policy support (QFX5230-64CD)—We've extended the Junos Environment Monitoring (EM) policy to include optics temperature sensors for QFX5230-64CD switches. The policy includes the following features:

    • The Optics EM policy incorporates periodically polled temperature readings of optical modules in the system to automatically manage the fan speed.

    • Junos OS Evolved automatically triggers shutdown of 100GbE and 400GbE optics when the system breaches the Fire Shutdown threshold.

    • The Optics EM policy is enabled by default on all 100GbE and 400GbE optics interfaces, except for loopback optics and direct attach copper (DAC) cables.

    You can use the set chassis fpc fpc_slot pic pic_slot port port_no no-temperature-monitoring command to explicitly disable the Optics EM policy on specific WAN ports. Use the show chassis environment command to view the optics temperature.

    [See temperature-sensor.]

  • Support for multiple speeds (QFX5130E-32CD)—You can configure 10-Gbps, 25-Gbps, 40-Gbps, or 100-Gbps port speed on QFX5130E-32CD switches.

    [See speed (Ethernet).]

  • Chassis management on new FEB (QFX5700E)—We provide support for chassis management features on QFX5700E-FEB, a new Forwarding Engine Board (FEB) for QFX5700 switches. You can use the following commands to manage power and view QFX5700E-FEB information:

    • set chassis feb slot slot-number power (off | on) command to turn on or turn off the FEB

    • show chassis feb and show chassis environment feb commands to display FEB status information

    • request chassis feb slot slot-number (offline | online | restart) to take the specified FEB offline, bring it online, or restart the FEB

    [See power, show chassis feb, request chassis feb, and show chassis environment.]

  • Resiliency support (QFX5130-48C, QFX5240-64OD, and QFX5240-64QD)—We support resiliency for platform components on the QFX5130-48C, QFX5240-64OD, and QFX5240-64QD devices.
