Troubleshooting the SyncE Configuration
Table 10-2
list the debug commands that are available for troubleshooting the SyncE configuration on
the Cisco ASR 1000 Series Router:
Note
Before you troubleshoot, ensure that all the network clock synchronization configurations are complete.
Table 10-3
provides the information about troubleshooting scenarios that you may encounter while
configuring the SyncE.

Troubleshooting Scenarios
Problem
Solution
Clock selection
•
Verify that there are no alarms on the interfaces. Use the
show
network-clock synchronization detail
command to check this.
•
Ensure that the nonrevertive configurations are in place.
•
Reproduce the issue and collect the logs using the
debug network-clock
errors
,
debug network-clock event
, and
debug network-clock sm
commands. Contact Cisco Technical Support if the issue persists.
Incorrect QL values
•
Ensure that there is no framing mismatch with the SSM option.
•
Reproduce the issue using the
debug network-clock errors
and
debug
network-clock event
commands. Also, enable the
debug hw-module
subslot
command.
(
this is specific to SIP-400
)
.
Alarms
•
Reproduce the issue using the
debug platform network-clock
command enabled in the RP. Alternatively, enable the
debug
network-clock event
and
debug network-clock errors
commands.
