CISCO-OPTICAL-MONITOR-MIB: View SNMP OID List / Download MIB

This MIB module defines objects to monitor optical characteristics and set corresponding thresholds on the optical interfaces in a network element.

This table provides objects to monitor optical parameters in a network element. It also provides objects for setting high and low threshold levels, with configurable severities, on these monitored parameters.

An entry in the cOpticalMonTable provides objects to monitor an optical parameter and set threshold levels on that parameter, at an optical interface. Note that the set of monitored optical parameters may vary based on interface type, direction, and monitoring location. Examples of interfaces that can have an entry in this table include optical transceivers, interfaces before and after optical amplifiers, and interfaces before and after optical attenuators.

This object indicates the direction monitored for the optical interface, in this entry.

This object indicates whether the optical characteristics are measured before or after adjustment (e.g. optical amplification or attenuation), at this interface.

This object specifies the optical parameter that is being monitored in this entry.

This object gives the value measured for the particular optical parameter specified by the cOpticalMonParameterType object.

This object is used to set a high alarm threshold on the optical parameter being monitored. An alarm condition will be raised if the value given by cOpticalParameterValue goes from below the value configured in this object to above the value configured in this object, or if the initial value of cOpticalParameterValue exceeds the value configured in this object. For network elements that incorporate a soak time in the status indications, this alarm will be indicated in the cOpticalParamAlarmStatus object only after it persists for a period of time that equals the set soak interval. The severity level of the alarm is specified by the cOpticalParamHighAlarmSev object. When the cOpticalMonParameterType object is set to 'power' for the receive direction at a transceiver, this object specifies the receiver saturation level.

This object is used to specify a severity level associated with the high alarm threshold given by the cOpticalParamHighAlarmThresh object. The values 'notAlarmed', 'notReported', and 'cleared' do not apply. The severity level configured in this object must be higher than the level configured in the cOpticalParamHighWarningSev object.

This object is used to set a high warning threshold on the optical parameter being monitored. A threshold crossing condition will be indicated if the value given by cOpticalParameterValue goes from below the value configured in this object to above the value configured in this object, or if the initial value of cOpticalParameterValue exceeds the value configured in this object. For network elements that incorporate a soak time in the status indications, this threshold violation will be indicated in the cOpticalParamAlarmStatus object only after it persists for a period of time that equals the set soak interval. This threshold crossing may or may not be alarmed or reported, based on the severity level specified by the cOpticalParamHighWarningSev object.

This object is used to specify a severity level associated with the high warning threshold given by the cOpticalParamHighWarningThresh object. The values 'critical', 'major', and 'cleared' do not apply. The severity level configured in this object must be lower than the level configured in the cOpticalParamHighAlarmSev object. If this object is set to 'notReported', no notifications will be generated when this threshold is exceeded, irrespective of the value configured in the cOpticalNotifyEnable object.

This object is used to set a low alarm threshold on the optical parameter being monitored. An alarm condition will be raised if the value given by cOpticalParameterValue goes from above the value configured in this object to below the value configured in this object, or if the initial value of cOpticalParameterValue is lower than the value configured in this object. For network elements that incorporate a soak time in the status indications, this alarm will be indicated in the cOpticalParamAlarmStatus object only after it persists for a period of time that equals the set soak interval. The severity level of this alarm is specified by the cOpticalParamLowAlarmSev object. When the cOpticalMonParameterType object is set to 'power' for the receive direction and when the interface supports alarms based on loss of light, this object specifies the optical power threshold for declaring loss of light. Also, when optical amplifiers are present in the network, in the receive direction, this value may need to be configured, since the noise floor may be higher than the minimum sensitivity of the receiver.

This object is used to specify a severity level associated with the low alarm threshold given by the cOpticalParamLowAlarmThresh object. The values 'notAlarmed', 'notReported', and 'cleared' do not apply. The severity level configured in this object must be higher than the level configured in the cOpticalParamLowWarningSev object.

This object is used to set a low warning threshold on the optical parameter being monitored. A threshold crossing condition will be indicated if the value given by cOpticalParameterValue goes from above the value configured in this object to below the value configured in this object, or if the initial value of cOpticalParameterValue object is lower than the value configured in this object. For network elements that incorporate a soak time in the status indications, this threshold violation will be indicated in the cOpticalParamAlarmStatus object only after it persists for a period of time that equals the set soak interval. This threshold crossing may or may not be alarmed or reported, based on the severity level specified by the cOpticalParamLowWarningSev object.

This object is used to specify a severity level associated with the low warning threshold given by the cOpticalParamLowWarningThresh object. The values 'critical', 'major', and 'cleared' do not apply. The severity level configured in this object must be lower than the level configured in the cOpticalParamLowAlarmSev object. If this object is set to 'notReported', no notifications will be generated when this threshold is exceeded, irrespective of the value configured in the cOpticalNotifyEnable object.

This object is used to indicate the current status of the thresholds for the monitored optical parameter on the interface. If a threshold is currently being exceeded on the interface, the corresponding bit in this object will be set to 1. Otherwise, the bit will be set to 0.

This object indicates the threshold value of the highest severity threshold that is currently being exceeded on the interface, for the optical parameter. If no threshold value is currently being exceeded, then the value '-1000000' is returned.

This object indicates the maximum severity of any thresholds that are currently being exceeded on the interface, for the optical parameter.

This object specifies the value of sysUpTime at the last time a threshold related to a particular optical parameter was exceeded or cleared on the interface.

This object gives the number of previous 15 minute intervals for which valid performance monitoring data has been stored on the interface. The value of this object will be n (where n is the maximum number of 15 minute intervals supported at this interface), unless the measurement was (re-)started within the last (nx15) minutes, in which case the value will be the number of previous 15 minute intervals for which the agent has some data.

This object gives the number of previous 24 hour intervals for which valid performance monitoring data has been stored on the interface. The value of this object will be 0 if the measurement was (re-)started within the last 24 hours, or 1 otherwise.

This object indicates if the current value of a particular threshold in this entry is user configured value or it is a system default value. It also allows user to specify the list of thresholds for this entry which should be restored to their system default values. The bit 'highAlarmThresh' corresponds to the object cOpticalParamHighAlarmThresh. The bit 'highWarnThresh' corresponds to the object cOpticalParamHighWarningThresh. The bit 'lowAlarmThresh' corresponds to the object cOpticalParamLowAlarmThresh. The bit 'lowWarnThresh' corresponds to the object cOpticalParamLowWarningThresh. A value of 0 for a bit indicates that corresponding object has system default value of threshold. A value of 1 for a bit indicates that corresponding object has user configured threshold value. A user may only change value of each of the bits to zero. Setting a bit to 0 will reset the corresponding threshold to its default value. System will change a bit from 0 to 1 when its corresponding threshold is changed by user from its default to any other value. Bits: 'highAlarmDefThresh': 0, 'lowWarnDefThresh': 3, 'highWarnDefThresh': 1, 'lowAlarmDefThresh': 2.

This object specifies the minimum severity threshold governing the generation of cOpticalMonParameterStatus notifications. For example, if the value of this object is set to 'major', then the agent generates these notifications if and only if the severity of the alarm being indicated is 'major' or 'critical'. The values of 'notReported', and 'cleared' do not apply. The value of '0' disables the generation of notifications.

This object specifies the types of transceivers for which optical monitoring is enabled. A value of 1 for the bit 'all', specifies that optical monitoring functionality is enabled for all the types of transceivers which are supported by system and have optical monitoring capability. Bits: 'all': 0.

This object specifies the interval in minutes after which optical transceiver data will be polled by system repeatedly and updated in cOpticalMonTable when one or more bits in cOpticalMonEnable is set.

This object is used to indicate the number of seconds, in the current 15 minute or the current 24 hour interval, for which the optical performance data is not accounted for. In the receive direction, the performance data could be unavailable during these periods for multiple reasons like the interface being administratively down or if there is a Loss of Light alarm on the interface. In the transmit direction, performance data could be unavailable when the laser is shutdown.

This table stores performance monitoring data for the various optical parameters, collected over previous intervals. This table can have entries for one complete 24 hour interval and up to 96 complete 15 minute intervals. A system is required to store at least 4 completed 15 minute intervals.
