The SMPP log is a policy action-generated notification that contains all Short Message Peer-to-Peer Protocol notifications sent by the MPE device as well as delivery receipts from a Short Message Service Center (SMSC) server. In SMPP or XML mode, SMPP information appears on the Logs tab of the Policy Server Administration page. You can modify the severity of messages that are written to the SMPP log on the MPE configuration page. The default severity is WARN. See Configuring Log Settings to modify the settings.
