What's Changed

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

EVPN

  • Pseudowire status display update in show evpn vpws-instance output—For EVPN-VPWS pseudowire interfaces configured with protocols ccc, the Pseudowire field in the show evpn vpws-instance command output now displays the correct corresponding pseudowire status value Not Present when the local logical interface for the pseudowire connection is not present. Previously, this field still displayed the value CCC-Up even when the Status output field showed the local interface was not present.

    [See show evpn vpws-instance.]

General Routing

  • When you run the request vmhost zeroize command to zeroize a single Routing Engine on a dual Routing Engine device, the CLI incorrectly displays a message indicating that it will zeroize both Routing Engines.

  • log-tag functionality: The log-tag functionality is introduced in [set services service-set]

  • New option for debug collector data storage path —We've included the option <codeph>outdir</codeph> to specify an output directory for storing debug collector data in a customised path. This allows you to organise and access diagnostic information more efficiently, adapting storage to your specific requirements.

    [See request system debug-info

  • High-power optics support with CLI configuration option (QFX5240 and QFX5241)—You can enable high-power optics across all ports by configuring the high-power-mode option for each port. This feature supports up to 32 high-power modules, allowing you to benefit from enhanced connection capabilities. Ensure you configure the necessary settings to initialize and utilize high-power optics effectively, optimizing your network's performance.

  • Multicast queues share a common buffer pool (QFX5240-64OD, QFX5230-64CD, and QFX5250-64OE)—Multicast (mcast) queues will no longer use dedicated buffers and will instead share a common buffer pool. This change addresses limited multicast resources and the growing number of ports, which can constrain buffer availability and, in some cases, prevent certain ports from receiving buffer allocations.

Network Management and Monitoring

  • Deprecation of shell option—The shell option no longer requires a separate configuration and is now the default behavior. Deprecating the shell option enhances efficiency and simplifies management tasks.
