Issues Resolved in this Jloader 1.1.8 Release:

PROBLEM:

PR-873883

  • Platforms Impacted:      QFX3500
  • ISSUE:
    • Management port (ME0) disconnect and transmit errors seen intermittently when using copper SFP-T transceivers on the QFX3500.  
    • Using copper SFP-T transceivers on the SFP management module ME0/ME1 management interfaces (C0/C1), may result in disconnect problems causing transmit/output errors. The issue can be seen immediately or over an undetermined period of time.


PROBLEM:

PR-753509

  • Platforms Impacted:      QFX3600
  • ISSUE:
    • A defective fan module may show an incorrect LED status of "green" when system is in Line Card mode. The correct status for a defective fan tray is "amber" and blinking.


PROBLEM:

PR-832012

  • Platforms Impacted:      QFX3500
  • ISSUE:
    • Due to a change introduced in jloader 1.1.7, the second DIMM module is not initialized. This does not impact the QFX3500 as a standalone since it only uses the one DIMM module, but if the QFX3500 is used as a node the second DIMM module is required.
    • Impact: The field impact is very limited since QFX3500 units were never shipped with the 1.1.7 release.
 


Important Notes:

  • Prior to upgrading to the JUNOS 13.2 software release please review the attached documentation related to the new Enhanced Layer Support implementation.  This topic is unrelated to this jloader 1.1.8 release and is being provided as a seperate advisory due to the ELS implementation.
  • Release Notes:     Junos OS Release --- 13.2X50 for the EX Series and QFX Series
