Chapter 22 Configuring Clocking

			Configuring PTP for the Cisco ASR 901 Router
DETAILED STEPS
		Command	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:
		Router# configure terminal
	Step 3	ptp clock ordinary domain domain	Configures the PTP clock as an ordinary clock and enters
		hybrid	clock configuration mode.
		Example:	• domain—The PTP clocking domain number. Valid
			values are from 0 to 127.
		Router(config)# ptp clock ordinary	• hybrid—(Optional) Enables the PTP boundary clock
		domain 0
			to work in hybrid mode. Enables the hybrid clock such
			that the output of the clock is transmitted to the remote
			slaves.
	Step 4	clock-port port-nameslave	Sets the clock port to PTP slave mode and enters clock port
			configuration mode. In slave mode, the port exchanges
		Example:	timing packets with a PTP master clock.
		Router(config-ptp-clk)# clock-port
		Slave slave
	Step 5	transport ipv4 unicast interface	Sets port transport parameters.
		interface-type interface-number	• interface-type—The type of the interface.
		Example:	• interface-number—The number of the interface.
		Router(config-ptp-port)# transport
		ipv4 unicast interface loopback 0
	Step 6	clock source source-address	Specifies the address of a PTP master clock.
		Example:
		Router(config-ptp-port)# clock
		source 8.8.8.1
	Step 7	announce timeout value	(Optional) Specifies the number of PTP announcement
			intervals before the session times out.
		Example:	• value—The range is from 1 to 10. The default is 3.
		Router(config-ptp-port)# announce
		timeout 8
