  • Powering up and configuring data path of 400G-ZR and 400G-ZR-M optics is not instant and takes more time comparatively with other optics. You must wait before switching to a new speed configuration. PR1635443

Network Management and Monitoring

  • Junos OS Evolved has a feature to block or deny all hidden commands. To obtain this feature, configure the set system no-hidden-commands command. However, when you configure the command and commit, Junos OS blocks or denies the new netconf or junoscript XML sessions. As a workaround, delete the system no-hidden-commands configuration statement and start the new netconf/junoscript sessions. PR1590350

  • When you edit an ephemeral instance and if the show ephemeral-configuration merge command runs from another terminal, then the uncommitted changes in the ephemeral instance being edited appears in the output of the show ephemeral-configuration merge command. PR1629013
