Description

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. A stateful port configuration for PTP over Ethernet and default profile is supported only on boundary clock mode and not on ordinary clock mode.

For PTP over Ethernet, you can configure a port to function as both a timeReceiver port and a timeTransmitter port. This type of port is called a stateful port, or a bidirectional port. Such a stateful 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 timeTransmitter and timeReceiver roles or interfaces.

The passive-port-monitor and not-master are only available for PTX10004 and PTX10008.

Options

The remaining statements are explained separately. See CLI Explorer.
