Real-Time Performance Monitoring on ACX Series

Real-time performance monitoring (RPM) allows the user to perform service-level monitoring. When RPM is configured on a router, the router calculates network performance based on packet response time, jitter, and packet loss. RPM is supported on all ACX Series routers. You can configure these values to be gathered by HTTP, Internet Control Message Protocol (ICMP), TCP, and UDP requests. The router gathers RPM statistics by sending out probes to a specified probe target, identified by an IP address. When the target receives a probe, it generates responses that are received by the router. You set the probe options in the test test-name statement at the [edit services rpm probe owner] hierarchy level. You use the show services rpm probe-results command to view the results of the most recent RPM probes.


Packet Forwarding Engine timestamping is available only for ICMP probes and for UDP probes with the destination port set to UDP_ECHO port (7).

On ACX Series routers, the following statements are supported at the [edit services rpm] hierarchy level:


The ACX Series routers do not support the configuration of RPM probes to a routing instance along with the configuration of the hardware-timestamp statement.


ACX5000 line of routers do not support hardware-timestamp feature for RPM.
