SNMP Support
The system uses the Simple Network Management Protocol (SNMP) to send traps or events to the EMS server or an alarm server on the network. You must configure SNMP settings to communicate with those devices.
The SNMP MIB Reference describes the MIBs and SNMP traps supported by UPF and StarOS.
The following SNMP traps are available in support of their respective feature/functionality:
N4 Session/Node Level Reporting Procedure
The following traps are available to track status and conditions GTP-U path failure:
-
EGTPUPathFailure: This trap is generated when no response is received for GTP-U ECHO requests and data path failure is detected towards peer EPC Node.
-
EGTPUPathFailureClear: This trap is generated when the data path towards the peer node is available.
UP Session Recovery
The following traps are available after session recovery in the User Plane node:
-
ManagerFailure: This trap is generated when there is failure in the Software manager.
-
TaskFailed: This trap is generated when a noncritical task has failed and the appropriate recovery steps begin.
-
TaskRestart: This trap is generated when a noncritical task has restarted after an earlier failure.
-
SessMgrRecoveryComplete: This trap is generated when Session Manager recovery completes. This is typically caused by the failure of Session Manager task and successful completion of recovery.
-
ManagerRestart: This trap is generated when the identified manager task has been restarted.
Sx Association
The following traps are available to track the status of an Sx Association:
-
SxPeerAssociated: This trap is triggered when an Sx association is detected.
-
SxPeerAssociationRelease: This trap is triggered when an Sx association release is detected.
URL Blacklisting

-
BLDBError: Specifies the blacklisting OPTBLDB file error displayed with an error code.
-
BLDBErrorClear: Specifies the blacklisting OPTBLDB file error removed.
-
BLDBUpgradeError: Specifies the blacklisting OPTBLDB file error displayed with an error code.
-
BLDBUpgradeErrorClear: Specifies the Blacklisting OPTBLDB file error removed.
