Configuring Network Clock for Cisco ASR 901 Router
Troubleshooting ESMC Configuration
Use the following debug commands to troubleshoot the PTP configuration on the Cisco ASR 901 router:
Warning
We suggest you do not use these debug commands without TAC supervision.
Incorrect quality level (QL)
values when you use the show
network-clock
synchronization detail
command.
• Use the network clock synchronization SSM (option 1 | option 2) command to
confirm that there is no framing mismatch. Use the show run interface command to
validate the framing for a specific interface. For the SSM option 1 framing should be
an E1 and for SSM option 2, it should be a T1.
Error message
“%NETCLK-6-SRC_UPD:
Synchronization source 10m
0/0/0 status (Critical
Alarms(OOR)) is posted to all
selection process" is displayed.
• Interfaces with alarms or OOR cannot be the part of selection process even if it has
higher quality level or priority. OOR should be cleared manually. OOR can be cleared
by platform command clear platform timing oor-alarms.

Verify whether the ESMC packets are transmitted and
received with proper quality-level values.
