Troubleshooting Alarms, Logs, and Traps

The mobility system generates and retains the following congestion statistics:

Current congestion status peak congestion hits

• Time when the last congestion occurred
• Duration the last congestion lasted
• Number of calls rejected during congestion
• SNMP traps
• System logs

The following are GTP traps:

• jnxMbgPgwGtpPeerGWUpNotif

  The state of a GTP peer (control or data) has changed to UP. The GTP peer in trap is specified as “Rem: 200.6.1.2 Loc: 200.6.88.1 vrf: 0 [Ctrl]" where ‘Rem’ is the remote IP address, ‘Loc’ is the local IP address, and ‘vrf’ is the vrf instance. ‘Ctrl’ indicates that this is a GTP-C peer. ‘For the GTP-U peer, string ‘Data’ is present in place of ‘Ctrl’. This trap is generated only if GTP path management for the GTP peer is enabled.

• jnxMbgPgwGtpPeerDownNotif

  The state of a GTP peer (control or data) has changed to DOWN. The GTP peer in trap is specified as “Rem: 200.6.1.2 Loc: 200.6.88.1 vrf: 0 [Ctrl]" where ‘Rem’ is the remote IP address, ‘Loc’ is the local IP address,and ‘vrf’ is the vrf instance. ‘Ctrl’ indicates that this is GTP-C peer. For GTP-U peer, string ‘Data’ will be present in place of ‘Ctrl’. This trap is generated only if GTP path management for the GTP peer is enabled.

• jnxMbgPgwGtpPeerDNThresPerPeerNotif

  The total number of GTP peer (control or data) down events per GTP peer have crossed a threshold. The GTP peer in trap is specified as “Rem: 200.6.1.2 Loc: 200.6.88.1 vrf: 0 [Ctrl]" where ‘Rem’ is remote IP address, ‘Loc’ is local IP address, ‘vrf’ is vrf instance. ‘Ctrl’ indicates that this is GTP-C peer. For GTP-U peer, string ‘Data’ is present in place of ‘Ctrl’. If the number becomes higher than the “raise threshold,” then value 1 in field jnxMbgPgwGtpAlarmState indicates the alarm-state “raised,” and if the number becomes less than “clear threshold,”’ then value 0 in field jnxMbgPgwGtpAlarmState indicates alarm-state “cleared”. This trap is generated only if GTP path management for the GTP peer is enabled.

• jnxMbgPgwGtpNumDiscardedGtpcPktThresNotif

• The following are the Subscriber Manager traps:
  • jnxMbgPgwSMGtpEventNotif

    An important GTP event has occurred. jnxMbgPgwSMGTPEventType indicates the type of event (for example, “PDP_CTXT_CREATE_REJECT” ) and jnxMbgPgwSMGTPEventCause indicates the cause of the event (for example, “RESOURCE_ERR”).

  • jnxMbgPgwSMSubscribersThresGblNotif The total number of subscribers in the system has crossed a threshold.

    Note: For this trap and all remaining Subscriber Manager traps, two thresholds (“High” and “Low”) have been defined. For each threshold, this notification is generated when a threshold is crossed. The notification is not generated as soon as the threshold is crossed. The notification with jnxMbgPgwSMAlarmState = “RAISED” is generated if this notification has not already been generated for a threshold or the trap with jnxMbgPgwSMAlarmState = “CLEARED” has been generated for a threshold and the number stays above a threshold for a duration of 3 minutes (default) . The notification with jnxMbgPgwSMAlarmState = “CLEARED” is generated if the notification with jnxMbgPgwSMAlarmState = “CLEARED” has been generated for a threshold and the number stays below the threshold for a duration of 3 minutes (default). jnxMbgPgwSMAlarmThrshld indicates the threshold that was crossed. jnxMbgPgwSMAlarmState (RAISED/CLREAD) indicates if the number is more than the threshold (“RAISED”) or is less than the threshold (“CLEARED”).

  • jnxMbgPgwSMSubscribersThresPerSPNotif

    The total number of subscribers per services PIC has crossed a threshold. jnxMbgPgwSMSPICName indicates the services PIC for which this trap was generated.

  • jnxMbgPgwSMSessionEstFailThresPerSPNotif

    The total number of session establishment failures per Service PIC has crossed a threshold. jnxMbgPgwSMSPICName indicates the services PIC for which this trap was generated.

  • jnxMbgPgwSMSessionEstFailThresPerTCNotif

    The total number of session establishment failures per traffic class (GTPv1) has crossed a threshold. jnxMbgPgwSMQCIName indicates the TC (Traffic Class) for which this trap was generated.

  • jnxMbgPgwSMSessionEstFailThresPerQCINotif

    The total number of session establishment failures per QoS class identifier (GTPv2) has crossed a threshold. jnxMbgPgwSMQCIName indicates the QCI for which this trap was generated.

  • jnxMbgPgwSMBearersThresGblNotif

    The total number of bearers in the system has crossed a threshold.

  • jnxMbgPgwSMBearersThresPerSPNotif

    The total number of bearers per services PIC has crossed a threshold. jnxMbgPgwSMSPICName indicates the services PIC for which this trap was generated.
