Supported Time Synchronization Standard

Junos OS substantially supports RFC 1305, Network Time Protocol (Version 3) Specification, Implementation and Analysis.

RFC 2030, Simple Network Time Protocol (SNTP) Version 4 for IPv4, IPv6 and OSI, does not define a standard, but provides information about time synchronization technology. The IETF classifies it as “Informational.”

In CLI operational mode, you can set the current date and time on the router manually or from an NTP server.

On MX Series routers with the Channelized OC3/STM1 (Multi-Rate) Circuit Emulation MIC with SFP, Junos OS substantially supports RFC 4553, Structure-Agnostic Time Division Multiplexing (TDM) over Packet (SAToP)
