After starting the extended SSM protocol, in addition to judging the clock quality level and priority, it also judges the clock ID. After the network element receives the clock signal with ID, if it is judged that the clock signal is sent by the local station, the source is considered unavailable. In this way, even after passing through multiple sites, the network element can still recognize the clock signal sent by itself, preventing the formation of a timing loop.
