Verifies whether the ESMC packets are transmitted and received with proper quality-level values. 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. Table 10-3 Troubleshooting Scenarios Problem Clock selection Incorrect QL values Alarms Solution • 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. • 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). • 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. 10-16 Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide OL-16506-10

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.
