CISCO-NOTIFICATION-CONTROL-MIB: View SNMP OID List / Download MIB

This MIB provides network management support to regulate the transmission of notifications generated by a system providing networking services. The system could be generating several notifications pertaining to various events. Allowing every notification to be transmitted out may lead to the network being flooded with an excess of network management traffic. Hence it is required to regulate the generation and transmission of notifications. GLOSSARY Network Management Station (NMS) An external network entity that monitors and manages the network.

This object represents the notification control mode. The semantics are as follows. noControl - There is no control on notifications. forcedControl - All notifications configured through cNotifCtrlTable are filtered at all times. automaticControl - Notifications configured through cNotifCtrlTable are filtered only when number of notifications generated exceeds the value represented by cNotifCtrlThreshold in the given time interval represented by cNotifCtrlSamplingInterval. Enumeration: 'automaticControl': 3, 'noControl': 1, 'forcedControl': 2.

This object represents the current state of notification control. The semantics are as follows. controlOn - This indicates that notifications configured in cNotifCtrlTable are currently getting filtered on the system. This object will always be 'controlOn', when cNotifCtrlMode is 'forcedControl'. controlOff - This indicates that notifications configured in cNotifCtrlTable are currently not being filtered on the system. This object will always be 'controlOff', when cNotifCtrlMode is 'noControl'. If cNotifCtrlMode is set to 'automaticControl', the agent sets this object to 'controlOn', when number of notifications generated by the system exceeds the value represented by cNotifCtrlThreshold in the time interval represented by cNotifCtrlSamplingInterval. The agent sets this object to 'controlOff', when the number of notifications generated by the system falls below the value represented by cNotifCtrlThreshold in the time interval represented by cNotifCtrlSamplingInterval. Enumeration: 'controlOn': 1, 'controlOff': 2.

This object represents the threshold value to initiate controlling of notifications. Notifications will be controlled when the number of notifications generated by this system exceeds the threshold represented by this object in the sampling interval represented by cNotifCtrlSamplingInterval. The configured value takes effect only when cNotifCtrlMode is set to 'automaticControl'.

This object represents the sampling interval in which the notification generation rate will be monitored. The configured value takes effect only when cNotifCtrlMode is set to 'automaticControl'.

This object represents maximum number of rows possible in cNotifCtrlTable.

This object represents the next available free index in the cNotifCtrlTable. This number can be used as an index to create a valid entry into cNotifCtrlTable. A value of 0 indicates that no free indices are available to create entries in cNotifCtrlTable.

This table represents the notifications to be controlled. To control a particular notification, user creates a row uniquely indexed by cNotifCtrlIndex using the cNotifCtrlRowStatus object. The storage type of each row is indicated by cNotifCtrlStorageType. The agent filters out the notification depending on the current value of cNotifCtrlMode. The agent also indicates the current state of notification control through cNotifCtrlCurrentState. This notification control mechanism is illustrated as follows. cNotifCtrlTable contains the list of notifications, that need to be controlled from the agent when cNotifCtrlCurrentState is 'controlOn'. When cNotifCtrlMode is set to 'automaticControl', a timer is started for the time interval represented by cNotifCtrlSamplingInterval(eg: 10 mins) to monitor the number of notifications being generated by the agent. If the number of notifications generated exceeds the value represented by cNotifCtrlThreshold (eg: 100) before the timer expires, all notifications mentioned in cNotifCtrlTable are throttled. When the timer expires, it is restarted and the counter used to track the number of notifications generated is initialized to zero. This controlling of notifications will continue until the number of notifications generated falls below the threshold in the given interval. When cNotifCtrlMode is set to 'forcedControl', all the notifications mentioned in cNotifCtrlTable are always throttled, irrespective of the values of threshold and sampling interval.

A conceptual row in cNotifCtrlTable and corresponds to the notification to be filtered.

This object uniquely identifies an entry in cNotifCtrlTable.

This object represents the notification to be controlled.

This object represents the storage type for this conceptual row in cNotifCtrlTable. A value of 'volatile' indicates that the entry won't be persistent across system reloads. A value of 'nonVolatile' indicates that the entry will be persistent across system reloads.

This object represents the status of a conceptual row. Following objects are mandatory while creating an entry in this table: cNotifCtrlOID Entries can't be modified after the agent sets cNotifCtrlRowStatus to 'active'.

This object specifies a human readable string which has more descriptive information about the notification.

This collection of objects represents the configuration, monitoring and status parameters related to notification control.

The extended set of notification control variable(s).
