General Routing

  • On QFX5230 and QFX5240, scope of native-vlan-id is at the system level. Native vlan configured on one port, cannot be used as trunk vlan on some other port. It must be used as native vlan across all the ports. PR1827669

  • Link with the DAC (SFP56-50G-DAC-3M ) comes up with 25G default speed configuration when switch is rebooted. Hence, When 50G speed config is applied , peer side sees the link flap. PR1836697

  • On QFX5230-64CD device, channelisation 4x100g >>4x25g>>4x100g , 4x100g >> 4x10g>> 4x100g does not work in D30 image.

    • If customer wants to move, 4x100g to 4x25g, the work around is to move back to default configuration 400g, then try again required channelisation. e.g. 4x100g to 400g again 400g to 4x25g.

    • If QFX5230-64CD is already in issue state "4x100G (UP) >> 4x25G >> 4X100G (issue state) >> 400G >> 4x100G (down)", restart evo-pfemand is only way to recovery.

    PR1862413

  • Ungraceful swapping a 400G DAC with 400G optic (or vice-versa) might lead to traffic loss on QFX5000 Junos Evolved platforms. To avoid this issue, please follow the recommended steps to swap DAC/Optic:

    1. Mark the port as unused from CLI configuration.

    2. Swap the module (Optic/DAC).

    3. Delete unused CLI configuration on the port.

    PR1862711

  • QFX5130-32CD: 4x100G-DACBO - Traffic forwarding might fail to recover after manual ungraceful OIR of DAC cable To avoid this issue, please follow the recommended procedure to change the DAC cable: Recommended steps to change the DAC cable:

    1. Mark the port as unused from CLI configuration:

      set interfaces et-0/0/<x> unused

    2. Remove the DAC cable.

    3. Insert the DAC cable.

    4. Delete unused CLI configuration on the port.

      delete interfaces et-0/0/<x> unused
    PR1862893

Interfaces and Chassis

  • In all Junos-Evolved Operating Systems (OS), special characters entered in the description field of the set interfaces command in the Command Line Interface (CLI) might not be correctly encoded in XML outputs. This is a cosmetic issue. PR1824753

  • On QFX5240 set interfaces interface-range et-all member et-0/0/ configuration is not supported. PR1853302

  • Rx Signal Power does not get displayed on executing the following command: show interfaces transport pm optics current. Alternatively this can be looked up with the DOM CLI. PR1861680

Junos Telemetry Interface

  • The following list of telemetry sensor subscription paths have changed in order to be compliant with OpenConfig model definitions. A few of the sensors which were earlier in the OpenConfig hierarchy migrate to a newer Juniper native state model in the future releases.

    PR1861665

  • Some of the interface telemetry subscription paths do not work when subscribed at the leaf level. PR1862765

Network Management and Monitoring

  • IPv4/v6, PFC, ECN and Ingress Resource Drops related traffic counters moved to a new sensor - '/state/interfaces/interface/counters/'. Earlier these counters were part of '/junos/system/linecard/interface/traffic/' sensor & '/interfaces/interface/' sensor
