  • On-device packet capture (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 24.2R1, Junos devices support filtering and mirroring incoming and outgoing packets, sending those packets to the CPU, and saving them into a file. This feature, on-device packet capture, can help you with protocol and application analysis, debugging, troubleshooting, network forensics, audit trails, and network attack detection. On-device packet capture (or “self-mirroring”) sends the sampled copy to a CPU and writes the copy into a packet capture (.pcap) file. The process does not require you to use any device connected to your network device.

    More about on-device packet capture:

    • Operational commands allow you to start and stop the capture.
    • family is an optional parameter, and the families you can specify are inet, inet6, and any.
    • You can specify the write mode of the packet capture file—either circular (the default) or linear.
    • rate and max-packet-length properties apply to self-mirroring.
    • You can configure both “standard” port mirroring and self-mirroring on your device—you just need to ensure that you don't configure an individual port-mirroring instance for both mirroring types.

  • Support for enhanced request support information (ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7332, ACX7348, ACX7509, PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 24.2R1, we’ve deprecated the CLI option brief from the request support information command and introduced the following CLI options to the existing request support information command:

    • archive
    • with-logs
    • with-components
    • with-options.
