Hierarchy Level


Use this statement to configure the global time to wait before opening the interface to receive ESMC messages.

When an interface’s signal transitions out of the signal fail state, it must be fault-free for the global-wait-to-restore time before it is again considered by the clock selection process.

When the ESMC clock’s EEC quality level (QL) mode is enabled, it sends a signal failure to the clock selection process during the global wait-to-restore time. After the global wait-to-restore time ends, a new quality level value is sent to the clock selection process.

To override the global wait-to-restore time on a specific interface, include the wait-to-restore statement at the [edit chassis source interfaces (external-a | external-b | interface interface-name)] hierarchy level.



Set the time for the port signal to be up before the port is opened to receive and transmit ESMC messages.

  • Range: 0 through 12 minutes

  • Default: 5 minutes
