Support for hardware timestamping of Two-Way Active Measurement Protocol (TWAMP) and RPM probe messages (PTX5000)—Starting in Junos OS Release 21.2R1, we've extended support for hardware timestamping of TWAMP and RPM probe messages. Hardware timestamping is enabled by default for TWAMP, but you must configure it for RPM. You use TWAMP and RPM to measure IP performance between two devices in a network. By configuring hardware timestamping for RPM, you can account for the latency in the communication of probe messages and generate more accurate timers in the Packet Forwarding Engine. To configure hardware timestamping for RPM, include the hardware-timestamping statement at the [edit services rpm probe probe-owner test test-name] hierarchy level.
