12.3R12 Recommended Release for EX2200 and EX2200-C



Article ID: TSB17138 TECHNICAL_BULLETINS Last Updated: 10 Apr 2020Version: 5.0
Alert Type:
PSN - Product Support Notification
Product Affected:
EX2200 EX2200-C
Alert Description:
EX2200 and EX2200-C Switches have 512MB of Total Memory. With newer versions of JUNOS such as JUNOS 15.1, the overall memory footprint has increased. Due to this, current JUNOS 15.1 versions may not be suitable for these EX2200 and EX2200-C platforms, depending on the features, configuration and topology.  Our recommendation is that JUNOS 15.1 should not be installed on these switches at this time.

Due to a memory constraint of 512MB of Total Memory on the EX2200 and EX2200-C switches, it is recommended to use JUNOS 12.3 based Software Releases on EX2200 and EX2200-C platforms.

JUNOS 12.3 End of Engineering (EOE) has been extended to June 30, 2022 and End of Support (EOS) to June 30, 2024 for these switches. Please review the link to the EOL page below to get the EOL dates for JUNOS versions.

EX2200 / EX2200-C Software Recommendation:
  • The current recommendation for the EX2200/EX2200-C switches is 12.3R12.  


Please review this KB31903 before attempting a downgrade to 12.3R12 from the JUNOS 15.1 releases. There is a change in behavior in the way password hashing between these releases, which this KB31903 describes in detail, and ensures that passwords are stored in the same form between JUNOS 15.1 and 12.3R12 software releases.
