			Configuring Network Clock for Cisco ASR 901 Router
DETAILED STEPS
		Command or Action	Purpose
	Step 1	enable	Enables privileged EXEC mode.
			• Enter your password if prompted.
		Example:
		Router> enable
	Step 2	configure terminal	Enters global configuration mode.

		Example:	• QL is disabled by default.
			• ql-enabledmode can be used only when the
		Router(config)# network-clock
			synchronization interface is capable to send SSM.
		synchronization mode ql-enabled
	Step 4	esmc process	Enables the ESMC process.
			Note ESMC can be enabled globally or at the sync-E
		Example:	interface level
		Router(config)# esmc process
	Step 5	network-clock quality-level {tx	Forces the QL value for line or external timing output.
		rx} value {interface interface-name
		slot/sub-slot/port external
		slot/sub-slot/port gps
		slot/sub-slot controller
		slot/sub-slot/port}
		Example:
		Router(config)# network-clock
		quality-level rx qL-pRC external
		0/0/0 e1 crc4
