Claim 21:
22. The computer program product of claim 17, wherein the instructions further cause the network device to further determine the clock source when a first value of the first SSM code is equal to a second value of the second SSM code, a third value of the first eSSM code is equal to a fourth value of the second eSSM code, a first number of cascaded synchronous Ethernet equipment clocks (EECs) from a first nearest synchronization supply unit/primary reference clock (SSU/PRC) in the first SSM is equal to a second number of cascaded synchronous EECs from a second nearest SSU/PRC in the second SSM, a third number of cascaded enhanced synchronous EECs from the first nearest SSU/PRC is equal to a fourth number of cascaded enhanced synchronous EECs from the second nearest SSU/PRC, and a fifth value of a synchronous Ethernet master identity (SyncE master ID) in the first SSM is less than a sixth value of a SyncE master ID in the second SSM.
