New Features

We've introduced the following features in APM 3.1.0:

  • APM version 1—We introduced APMi protocol version 1.

    [See How APM Works]

  • Enhanced logging—Enable persistent logging and log exports to a syslog server during the setup. Fluentd collects logs from the configuration manager, address manager, entity manager, and provisioning manager. Fluentd then archives them to persistent files and optionally exports them to remote syslog servers.

    You can display file-based logs collected and stored since the time you start APM by using the apm svc-logs utility script. You can enable file-based logging when you set up APM.

    [See APM Installation Package and Display APM SVC Logging]

  • Entity-match configuration—Configure the entity-match list to map valid broadband network gateways (BNGs) running Junos OS Release 22.1 or later to a pool-domain-profile. The entity-match command defines which system IDs are allowed to connect.

    [See entity-match command]

  • Forced prefix release—Trigger APM to
    • Clean up any pool domains established by an entity.

    • Release an entity's domains and their associated pool prefixes back to each domain's source partition.

    [See request apm release entity command].
