### Instruction:
ICPE_DPM-6-DISCOVERY_HEARTBEAT_MISSING
### Response:
(Severity: 6), (Category: PKT_INFRA), (Description: The Discovery protocol requires a response to every heartbeat packet that is sent out. This syslog is output if the user has configured warning syslogs for a satellite. If the heartbeats continue to be missed, then the connection data to the satellite will be cleared and the session be re-established.), (Recommended Action: If making transport layer changes or re-configuring the satellite, then this syslog is probably expected and purely informational, so no further action is required. If unexpected, then check the transport layer between the host and the satellite and ensure that the satellite is working as expected. Copy the error message exactly as it appears on the console or in the system log, call your Cisco technical support representative and provide the representative with the gathered information.)
