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 that are supported by UPF and StarOS.

The following SNMP traps are available in support of their respective feature or 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 toward peer EPC Node.

  • EGTPUPathFailureClear: This trap is generated when the data path toward 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 Blockedlisting

The following SNMP trap are available in support of URL Blockedlisting feature:

  • BLDBError: Specifies the blockedlisting OPTBLDB file error that is displayed with an error code.

  • BLDBErrorClear: Specifies the blockedlisting OPTBLDB file error removed.

  • BLDBUpgradeError: Specifies the blockedlisting OPTBLDB file error displayed with an error code.

  • BLDBUpgradeErrorClear: Specifies the blockedlisting OPTBLDB file error removed.

Enabling SNMP Traps

Use the following configuration to enable an SNMP trap.

   snmp trap enable trap_name 
   end
