What's Changed

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

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.]

General Routing

  • A new counter Sessions hit due to high rate is added to show services service-sets screen-session-limit-counters command for all subscriber traffic. This counter tracks the sessions that come up on the screen irrespective of the alarm-without-drop configuration. When alarm-without-drop option is disabled, all the counters display updated statistics. When alarm-without-drop is enabled, then: - The screen-drop counters on show services service-sets statistic screen-drop command do not increase. - The sessions hit due to high rate value is displayed.

    [See alarm-without-drop (IDS Screen Next Gen Services), show services service-sets statistic screen-drops (Next Gen Services), and show services service-sets statistic screen-session-limit-counters (Next Gen Services).

  • 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.PR1869854

  • On the MPC7E-10G line card, when you configure the 10-Gigabit Ethernet ports to operate as 1-Gigabit Ethernet ports, use the speed statement at both the edit interfaces <interface name> gigether-options and edit interfaces <interface name> hierarchy levels.PR1879198

User Interface and Configuration

  • 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.

    [See show system storage.]

  • Stale ui-state.db data in persistent NETCONF sessions post-mgd restart-Existing NETCONF sessions might fetch stale data from ui-state.db after mgd -N restart. New sessions correctly map the refreshed database. Scripts must establish new sessions post-restart to access updated values. Functional configuration remains unaffected. Script failures monitoring "local-host" NETCONF sessions-Scripts might fail when including "local-host" NETCONF sessions in monitoring operations. Internal sessions are now excluded from tracking. Scripts must filter out "local-host" sessions. No impact to internal application functionality.PR1888557
