SATELLITE

tmnxSatelliteOperStateChange

Table 1. tmnxSatelliteOperStateChange properties
Property name	Value
Application name	SATELLITE
Event ID	2001
Event name	tmnxSatelliteOperStateChange
SNMP notification prefix and OID	TIMETRA-SATELLITE-MIB.tmnxSatelliteNotifications.1
Default severity	minor
Message format string	Possible messages: $tmnxHwIndex$ is in $tmnxHwOperState$ state - $tmnxSatNotifyFailureReason$ $tmnxHwIndex$ is in $tmnxHwOperState$ state
Cause	The tmnxSatelliteOperStateChange notification is generated when there is a change in tmnxHwOperState for the satellite.
Effect	The satellite has changed states. The tmnxSatNotifyFailureReason is only valid when tmnxHwOperState is 'failed (5)', and should otherwise be blank.
Recovery	Contact Nokia customer support if tmnxSatNotifyFailureReason does not provide enough information to rectify the situation.

tmnxSatSyncIfTimHoldover

Table 2. tmnxSatSyncIfTimHoldover properties
Property name	Value
Application name	SATELLITE
Event ID	2006
Event name	tmnxSatSyncIfTimHoldover
SNMP notification prefix and OID	TIMETRA-SATELLITE-MIB.tmnxSatelliteNotifications.6
Default severity	critical
Message format string	Synchronous timing interface on satellite $tmnxHwIndex$ is in holdover state
Cause	The tmnxSatSyncIfTimHoldover notification is generated when the synchronous equipment timing subsystem of the satellite transitions into a holdover state.
Effect	The transmit timing of all synchronous interfaces on the satellite are no longer synchronous with the host. This could result in traffic loss.
Recovery	Investigate the state of the two input timing references on the satellite and the links between the host and the satellite (i.e. the uplinks) that drive them for failures.

tmnxSatSyncIfTimHoldoverClear

Table 3. tmnxSatSyncIfTimHoldoverClear properties
Property name	Value
Application name	SATELLITE
Event ID	2007
Event name	tmnxSatSyncIfTimHoldoverClear
SNMP notification prefix and OID	TIMETRA-SATELLITE-MIB.tmnxSatelliteNotifications.7
Default severity	cleared
Message format string	Synchronous timing interface on satellite $tmnxHwIndex$, holdover state cleared
Cause	The tmnxSatSyncIfTimHoldoverClear notification is generated when the synchronous equipment timing subsystem of the satellite transitions out of the holdover state.
Effect	This notification is for informational purposes only.
Recovery	No recovery required.

tmnxSatSyncIfTimRef1Alarm

Table 4. tmnxSatSyncIfTimRef1Alarm properties
Property name	Value
Application name	SATELLITE
Event ID	2008
Event name	tmnxSatSyncIfTimRef1Alarm
SNMP notification prefix and OID	TIMETRA-SATELLITE-MIB.tmnxSatelliteNotifications.8
Default severity	minor
Message format string	Synchronous timing interface on satellite $tmnxHwIndex$, alarm $tmnxSatNotifySyncIfTimRefAlarm$ on reference 1
Cause	The tmnxSatSyncIfTimRef1Alarm notification is generated when an alarm condition on the first timing reference is detected.
Effect	If the other timing reference is free of faults, the satellite no longer has a backup timing reference. If the other timing reference also has a fault, the satellite will likely no longer be synchronous with the host.
Recovery	Investigate the state of the link between the host and the satellite (i.e. the uplink) that drives the first timing reference on the satellite for faults.

Property name	Value
Application name	SATELLITE
Event ID	2009
Event name	tmnxSatSyncIfTimRef1AlarmClear
SNMP notification prefix and OID	TIMETRA-SATELLITE-MIB.tmnxSatelliteNotifications.9
Default severity	cleared
Message format string	Synchronous timing interface on satellite $tmnxHwIndex$, alarm $tmnxSatNotifySyncIfTimRefAlarm$ on reference 1 cleared
Cause	The tmnxSatSyncIfTimRef1AlarmClear notification is generated when the alarm condition on the first timing reference is cleared.
Effect	This notification is for informational purposes only.
Recovery	No recovery required.

tmnxSatSyncIfTimRef1Quality

Table 6. tmnxSatSyncIfTimRef1Quality properties
Property name	Value
Application name	SATELLITE
Event ID	2004
Event name	tmnxSatSyncIfTimRef1Quality
SNMP notification prefix and OID	TIMETRA-SATELLITE-MIB.tmnxSatelliteNotifications.4
Default severity	minor
Message format string	Synchronous timing interface on satellite $tmnxSatId$, reference 1 received quality level $tmnxSatSyncIfTimingRef1RxQltyLvl$
Cause	The tmnxSatSyncIfTimRef1Quality notification is generated when the received quality level changes on the first timing reference of the satellite.
Effect	This notification is for informational purposes only.
Recovery	No recovery required.

tmnxSatSyncIfTimRef2Alarm

Table 7. tmnxSatSyncIfTimRef2Alarm properties
Property name	Value
Application name	SATELLITE
Event ID	2010
Event name	tmnxSatSyncIfTimRef2Alarm
SNMP notification prefix and OID	TIMETRA-SATELLITE-MIB.tmnxSatelliteNotifications.10
Default severity	minor
Message format string	Synchronous timing interface on satellite $tmnxHwIndex$, alarm $tmnxSatNotifySyncIfTimRefAlarm$ on reference 2
Cause	The tmnxSatSyncIfTimRef2Alarm notification is generated when an alarm condition on the second timing reference is detected.
Effect	If the other timing reference is free of faults, the satellite no longer has a backup timing reference. If the other timing reference also has a fault, the satellite will likely no longer be synchronous with the host.
Recovery	Investigate the state of the link between the host and the satellite (i.e. the uplink) that drives the second timing reference on the satellite for faults.

Default severity	cleared
Message format string	Synchronous timing interface on satellite $tmnxHwIndex$, alarm $tmnxSatNotifySyncIfTimRefAlarm$ on reference 2 cleared
Cause	The tmnxSatSyncIfTimRef1AlarmClear notification is generated when the alarm condition on the second timing reference is cleared.
Effect	This notification is for informational purposes only.
Recovery	No recovery required.

tmnxSatSyncIfTimRef2Quality

Table 9. tmnxSatSyncIfTimRef2Quality properties
Property name	Value
Application name	SATELLITE
Event ID	2005
Event name	tmnxSatSyncIfTimRef2Quality
SNMP notification prefix and OID	TIMETRA-SATELLITE-MIB.tmnxSatelliteNotifications.5
Default severity	minor
Message format string	Synchronous timing interface on satellite $tmnxSatId$, reference 2 received quality level $tmnxSatSyncIfTimingRef2RxQltyLvl$
Cause	The tmnxSatSyncIfTimRef2Quality notification is generated when the received quality level changes on the second timing reference of the satellite.
Effect	This notification is for informational purposes only.
Recovery	No recovery required.

SNMP notification prefix and OID	TIMETRA-SATELLITE-MIB.tmnxSatelliteNotifications.2
Default severity	minor
Message format string	Synchronous timing interface on satellite $tmnxSatId$, timing reference changed to $tmnxSatSyncIfTimingRef1InUse$

Effect	This event is for notification only.
Recovery	No recovery required.

tmnxSatSyncIfTimSystemQuality

Table 11. tmnxSatSyncIfTimSystemQuality properties
Property name	Value
Application name	SATELLITE
Event ID	2003
Event name	tmnxSatSyncIfTimSystemQuality
SNMP notification prefix and OID	TIMETRA-SATELLITE-MIB.tmnxSatelliteNotifications.3
Default severity	minor
Message format string	Synchronous timing interface on satellite $tmnxSatId$, system quality level changed to $tmnxSatSyncIfTimingSystemQltyLvl$
Cause	This notification may be triggered for the following reasons: 1) There has been a switch in the timing reference in use by the network element, either because the previously active timing reference was disqualified, or to ensure that the network element is using the timing reference with the best timing quality. 2) There has been a change in the active timing reference's quality and the change does not result in a timing reference switch. 3) The network element has transitioned into or out of the holdover state.
Effect	The system quality level is used to determine the SSM code transmitted on synchronous interfaces. This may affect the SSM code transmitted on some or all interfaces, which may affect the distribution of timing throughout the network.
Recovery	If the customer is expecting the system to be locked to a reference of a particular quality and the system quality has decreased, the customer will need to determine the root cause (for example, loss of communication with a satellite) and resolve the issue.
