Configuring PTP for the Cisco ASR 901 Router

	Command or Action	Purpose
Step 8	transport ipv4 unicast interface	Sets port transport parameters.
	interface-type interface-number	• interface-type—The type of the interface.
	[negotiation]
		• interface-number—The number of the interface.
	Example:	• negotiation—(Optional) Enables dynamic discovery
	Router(config-ptp-port)# transport	of slave devices and their preferred format for sync
	ipv4 unicast interface Loopback 1	interval and announce interval messages.
	negotiation
Step 9	exit	Exits clock port configuration mode.
	Example:
	Router(config-ptp-port)# exit

Verifying PTP modes

Ordinary Clock

Use the show ptp clock dataset current command to display the sample output.

Router#show ptp clock dataset current
