But for today’s deployments, ptp-hw-assist remains the gold standard. It transforms a general-purpose IP router into a true telecom-grade timing device.
If ptp-hw-assist is configured on a , PTP cannot be enabled at the Ethernet port level. ptp-hw-assist nokia
Nokia often deploys the (Photonic Service Switch) or OSA 5400 series as PTP grandmasters, using GNSS (GPS/Beidou/Galileo) as primary reference. The ptp-hw-assist feature on downstream boundary clocks and ordinary clocks ensures traceability of timing to the grandmaster. Nokia often deploys the (Photonic Service Switch) or
However, standard software-based PTP implementations often struggle to meet the stringent sub-microsecond accuracy required by modern mobile front-haul and back-haul networks. This is where hardware assistance becomes non-negotiable. In the context of Nokia’s Service Router (SR) and 7750 Service Router (SR) OS portfolios, the configuration keyword represents a pivotal enabling feature. This is where hardware assistance becomes non-negotiable
: Identify the L3 interface (IP interface) where timing is required.
Configuration example:
You can verify active timestamping points by checking the PTP peer or port status in the Nokia Documentation Center or via show commands. Hardware Support and Requirements
