Chapter 22 Configuring Clocking

Configuring PTP for the Cisco ASR 901 Router

Configuring a Hybrid Boundary Clock

Complete the following steps to configure a hybrid clocking in PTP boundary clock mode.

Prerequisites

When configuring a hybrid clock, ensure that the frequency and phase sources are traceable to the same master clock.

Restrictions

Hybrid clock is not supported with ToP as network-clock. It needs a valid physical clock source, for example, Sync-E/BITS/10M/TDM.

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:
		Router# configure terminal
	Step 3	ptp clock boundary domain domain	Configures the PTP boundary clock and enters clock
		hybrid	configuration mode.
		Example:	• domain—The PTP clocking domain number. Valid
			values are from 0 to 127.
		Router(config)# ptp clock boundary	• hybrid—(Optional) Enables the PTP boundary clock
		domain 0 hybrid
			to work in hybrid mode. Enables the hybrid clock such
			that the output of the clock is transmitted to the remote
			slaves.
