Release Information

Statement introduced in Junos OS Release 12.3X51 for the ACX Series Universal Metro Routers.


Configure the stateful port or bidirectional port with parameters. A stateful port is useful when you configure PTP over Ethernet for multicast mode of transmission of PTP traffic.

For PTP over Ethernet, you can configure a port to function as both a slave port and a master port. This type of port is called a dynamic port, a stateful port, or a bidirectional port. Such a dynamic port enables the transfer of frequency for synchronization services, in addition to time and phase alignment, when PTP functionality is not hop-by-hop and you have provisioned master and slave roles or interfaces as specified in ITU-T G.8265.1 Precision time protocol telecom profile for frequency synchronization.


The remaining statements are explained separately. See CLI Explorer.
