Table 1. Error event messages
Error event message	Possible causes and recommended corrective Aation
OptimaModelError	The network model used by BWoD from the Optimization Engine is corrupt or is missing key data needed to properly support BWoD. Possible causes include network discovery issues or synchronization problems between the Optimization Engine and Topology Services. Try restarting the Optimization Engine pod to rebuild the model. This error can also occur if the time required to discover a policy and add it to the model after it has been deployed exceeds the Deployment Timeout option set for BWoD. The default is 30 seconds, sufficient for small to medium-sized networks. However, larger networks may require additional time.
NATSTimedOutError	The deployment of a bandwidth policy through SR-PCE exceeds the Deployment Timeout option set for BWoD. Increase the Deployment Timeout option to allow for additional time for deployments in larger networks.
Traceback or other errors found in the log file	Contact your Cisco service representative.
