How to Implement NTP on Cisco IOS XR Software

Verifying the Status of the External Reference Clock

This task explains how to verify the status of NTP components.

Note The commands can be entered in any order.

SUMMARY STEPS

1.show ntp associations [detail] [location node-id]

2.show ntp status [location node-id]

DETAILED STEPS

	Command or Action	Purpose
Step 1
	show ntp associations [detail] [location	Displays the status of NTP associations.
	node-id]
	Example:
	RP/0/RP0/CPU0:router# show ntp associations
Step 2
	show ntp status [location node-id]	Displays the status of NTP.
	Example:
	RP/0/RP0/CPU0:router# show ntp status

Examples

The following is sample output from the show ntp associations command:

RP/0/0/CPU0:router# show ntp associations
