Configuring Synchronous Ethernet Chapter 10 Synchronous Ethernet Support ESMC EVENT pkts in: 0 ESMC EVENT pkts out: 0 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: Table 10-2 SyncE Debug Commands Debug Command debug platform network-clock debug esmc error debug esmc event debug esmc packet [interface ] debug esmc packet rx [interface ] debug esmc packet tx [interface ] Purpose Debugs issues related to the network clock, such as alarms, OOR, active-standby sources not selected correctly, and so on. 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
