PTP AES67, SMPTE ST-2059-2, and AES67+SMPTE profiles

You can enable the AES67, SMPTE ST-2059-2, and AES67+SMPTE profiles to support video applications for capture (for example, cameras), video edit, and playback to be used in professional broadcast environments. The standard allows multiple video sources to stay in synchronization across various equipment by providing time and frequency synchronization to all devices. 

This profile supports Precision Time Protocol (PTP) over IPv4 multicast and ordinary and boundary clocks. To configure the AES67, SMPTE ST-2059-2, and AES67+SMPTE profiles, enable one of the aes67, smpte, or aes67-smpte statements at the [edit protocols ptp profile-type] Junos OS CLI hierarchy.
