Enhanced management traffic (MX Series)—Starting in Junos OS Release 22.4R1, you can prioritize the management traffic per packet classification. This enhancement improves the performance of the internal traffic and management traffic. The enhancement also improves packet processing.
We’ve also introduced three operational commands that provide easily interpretable results for debugging packet path issues in the Routing Engine.
[See priority, show system statistics netisr per-priority-stats, show system statistics netisr qdrops, and show system statistics netisr socket-drops.]

1:N port mirroring for sending a source packet to multiple Layer 2 destinations (EX3400, EX4100, EX4100-F, EX4300-MP, and EX4400 switches)—Starting in Junos OS Release 22.4R1, you can use the 1:N port mirroring feature to mirror traffic to multiple Layer 2 destinations, by configuring one or both of the following configurations:
-
A port-mirroring instance that is based on a firewall filter. Use the configuration statements in the
[edit forwarding-options port-mirroring instance]
hierarchy. -
A native analyzer. Use the configuration statements in the
[edit forwarding-options analyzer]
hierarchy.
For both configuration methods, you must also configure next-hop groups with a group type of
layer-2
to direct the mirrored packets to their destinations. -
