1.1. New PTP Instance types and features

The PTP implementation has been updated with the following new features:

  1. Peer to peer (P2P) Transparent clock (TC) supporting 1-step and 2-step. See this section for more details on how to configure it.

  2. End to end (E2E) Transparent clock (TC) supporting 1-step and 2-step. See this section for more details on how to configure it.

  3. Support for PTP over a PRP interface. The support here is limited to 3-way boundary clock (TWBC). No configuration is needed. If a redbox is enabled on a given interface then this mode is activated.

  2. A new YANG leaf called mode, has been added in the single-leaky-bucket container. This can be used to configure whether the shaper should use line rate or data rate.

  3. A new YANG leaf called mode has been added in the credit-based container. This can be used to configure whether the shaper should use line rate or data rate.
