Network Management and Monitoring

  • Enhanced CFM support (ACX5448, ACX5448-M, and ACX5448-D)—Starting in Junos OS Release 21.2R1, you can enable the performance monitoring responder functionality without enabling the transmission of continuity check messages (CCM). To enable the performance monitoring responder functionality without enabling CCM transmission, configure our new configuration statement send-zero-interval-ccm under the [edit protocols protocols oam ethernet connectivity-fault-management] hierarchy level. After you configure the statement, if the continuity-check is not enabled, CCMs are not transmitted, but are programmed to receive the CFM packets for that maintenance endpoint (MEP) level.

    [See IEEE 802.1ag OAM Connectivity Fault Management Overview and connectivity-fault-management (EX Series Switch Only).]

  • Support for port mirroring (ACX710)—Starting in Junos OS Release 21.2R1, you can use analyzers to mirror copies of packets to a configured destination. You configure the analyzer at the [edit forwarding-options analyzer] hierarchy level.
