In a 1588 ATR domain, a clock client establishes a client/server relationship only with a remote clock server. The client initiates unicast negotiation requests to the server and uses PTP packets to implement clock recovery.
Before configuring 1588 ATR time synchronization, complete the following tasks:
Configure static routes or IGP to ensure reachable routes among nodes.
Configure the clock server to properly process clock signals from the BITS source.
