Troubleshooting Tips

Note Before you troubleshoot, ensure that all the network clock synchronization configurations are complete.

Table 22-1provides the troubleshooting scenarios encountered while configuring the synchronous ethernet.

Table 22-1 Troubleshooting Scenarios for Synchronous Ethernet Configuration

Problem	Solution
Clock selection	• Verify that there are no alarms on the interfaces. Use the show network-clock
	synchronization detail RP command to confirm.
	• Use the show network-clock synchronization command to confirm if the system is in
	revertive mode or non-revertive mode and verify the non-revertive configurations as
	shown in this example:
	Router# show network-clocks synchronization
	Symbols:	En	- Enable, Dis - Disable, Adis - Admin Disable
		NA	- Not Applicable
		*	- Synchronization source selected
		#	- Synchronization source force selected

&- Synchronization source manually switched Automatic selection process : Enable

Equipment Clock : 2048 (EEC-Option1)

Clock Mode : QL-Disable

ESMC : Disabled

SSM Option : 1

T0 : GigabitEthernet0/4

Hold-off (global) : 300 ms

Wait-to-restore (global) : 300 sec

Tsm Delay : 180 ms

Revertive : Yes<<<<If it is non revertive then it will show NO here.

Note The above example does not show the complete command output. For complete command output, see the example in Verifying the Synchronous Ethernet configuration.

•Reproduce the current issue and collect the logs using the debug network-clock errors, debug network-clock event, and debug network-clock sm RP commands.

Warning We suggest you do not use these debug commands without TAC supervision.

•Contact Cisco technical support if the issue persists.
