PTP clocking: Secure client

A clock client is the remote PTP host, which receives time from the PTP primary and is in a client relationship to the primary. The maximum number of configured clock clients is 512. The clock client is included in the configuration of the primary clock. Three different types of downstream clients are supported. You can configure any combination of these three types of clients for a given primary. For a secure client, you must configure a full and exact IP address, after which it joins the primary clock through unicast negotiation. To configure a secure client, include the clock-client ip-address statement with the exact IP address of the PTP host at the [edit protocols ptp master interface interface-name unicast-mode] hierarchy level.
