  • Support for ephemeral database cyclic versioning and resizing (MX240, MX480, MX960, MX2010, MX2020, MX10004, MX10008, MX10016, and vMX)—Starting in Junos OS Release 23.2R1, Junos devices implement cyclic versioning and database resizing to more effectively manage the space used by the ephemeral configuration database. The cyclic version value defines the number of versions of an ephemeral database for which the system stores deleted configuration objects. During a commit operation, the system reclaims the space occupied by objects deleted in the previous database version relative to the current database version as determined by the cyclic version value. You can also configure the device to resize the database when its size exceeds certain thresholds. With effective space management, you can prevent the database from hitting the maximum database size and improve performance by reducing database fragmentation.

  • Support protobuf format—Starting in Junos OS Release 23.2R1, Juniper Networks® SRX Series Firewalls support protocol buffers (protobuf) format to encode the security log. SRX Series Firewalls send the encoded security log to the target device. The logs are saved on the target and decoded for readability.

    The primary purpose of protobuf is to reduce the size of stream logs (compared to syslog and sd-syslog) and increase the events per second (EPS) ratings with the log server.
