  • Bandwidth-based MACsec license support (MX240, MX304, MX480, MX960, MX2008, MX2010, MX2020, MX10003, MX10004, MX10008, and MX10016)—Starting in Junos OS Release 23.1R1, the Media Access Control security (MACsec) support on the listed devices requires installation of MACsec bandwidth licenses. These licenses are perpetual.

    The MACsec feature licenses are available in the following variants:

    • S-MX-1C-MSEC-P—100-Gigabit Ethernet license

    • S-MX-4C-MSEC-P—400-Gigabit Ethernet license

    • S-MX-4C8-MSEC-P—480-Gigabit Ethernet license

    The minimum number of MACsec bandwidth licenses installed must be greater than or equal to the configured bandwidth of MACsec-enabled ports.

    You can view the MACsec bandwith license usage by using the command show system macsec license. You can view the usage of different feature licenses by using the command show system license.

    Juniper Agile Licensing supports soft enforcement for MACsec bandwidth licenses. With soft enforcement, the feature remains operational even without a valid license. However, you will receive commit warnings and periodic alarms insisting on installation of a valid license.

  • Support to trigger license alarm at configured time interval (EX Series, MX Series, QFX Series, and SRX Series)—Starting in Junos OS Release 23.1R1, you can set the time interval at which you want to trigger alarms for features or capacity that do not have licenses installed.

    To set the alarm log frequency, use the command log-frequency in the set system license hierarchy.
