PTP path trace mechanism

You can use a path trace mechanism to detect PTP loops in a PTP ring topology over an IPv4 network. A path trace is the route that a PTP announce message takes through the network trail of boundary clocks and is tracked through the path trace TLV in the announce message. The path trace sequence contains the clock ID of each boundary clock that an announce message traverses. To view the path trace, use the show ptp path-trace detail operational mode command.
