cisco-system-ext-mib.mib object
Introduction
Most network devices and programs ship with so-called MIB files to describe the parameters and meanings (i.e.: friendly names) which are available for monitoring via SNMP.
ActiveXperts Network Monitor 2025 can import vendor-specific MIB files, so it can be used to monitor specific OID's (Object Identifiers).
This way, you can monitor your devices, computers, etc. by selecting your relevant OID's by name.
ActiveXperts Network Monitor 2025 can import MIB file cisco-system-ext-mib and use it to monitor vendor specific OID's.

Object view of cisco-system-ext-mib:
  
    
      | Scalar Object | 
    
  
  
    
      | cseSysCPUUtilization | 
      .1.3.6.1.4.1.9.9.305.1.1.1 | 
    
    
      | 
        The average utilization of CPU on the active
        supervisor.
       | 
    
    
      | cseSysMemoryUtilization | 
      .1.3.6.1.4.1.9.9.305.1.1.2 | 
    
    
      | 
        The average utilization of memory on the active
        supervisor.
       | 
    
    
      | cseSysConfLastChange | 
      .1.3.6.1.4.1.9.9.305.1.1.3 | 
    
    
      | 
        The local date and time when the
        configuration was last changed. This object will
        be set to zero on power cycle or on reboot of
        the system. Also, if the clock is changed on
        local system it is set to zero. 
       | 
    
    
      | cseSysAutoSync | 
      .1.3.6.1.4.1.9.9.305.1.1.4 | 
    
    
      | 
        The state of the auto synchronization of images
        between the active and standby supervisor.
        Setting the value to sync when the existing value
        is sync, has no effect on the operation. 
       | 
    
    
      | cseSysAutoSyncState | 
      .1.3.6.1.4.1.9.9.305.1.1.5 | 
    
    
      | 
        The status of the current auto synchronization
        process, or if no such process is in progress,
        then the state of the most recent one.  The
        value 'notStarted' indicates no auto synchronization
        process has occurred recently.
       | 
    
    
      | cseWriteErase | 
      .1.3.6.1.4.1.9.9.305.1.1.6 | 
    
    
      | 
        This object is used to initiate a write erase on the
        device's saved configuration file(s) from which the
        device loads its configuration when it restarts.
        If the value of this object is set to 'eraseAll', then
        all the saved configurations are removed.
        No action is taken when the this object is set to
        'noOp'.
        When read, the value of this object is always 'noOp'.
       | 
    
    
      | cseSnmpErrorEntry | 
      .1.3.6.1.4.1.9.9.305.1.2.1.1 | 
    
    
      | 
        An entry (conceptual row) in the  cseSnmpErrorTable, containing
        information about an error which has recently caused a SNMP
        SetRequest to fail.  An entry is created by the agent
        on the occurrence of an error, and is deleted approximately 5
        minutes later. The reasons for this are :
        - to prevent old entries clogging the table.
        - optimal utilization of the resources like memory.
       | 
    
    
      | cseHaRestartReason | 
      .1.3.6.1.4.1.9.9.305.1.3.2 | 
    
    
      | 
        The reason for most recent restart of a service on the
        'active' supervisor.
       | 
    
    
      | cseHaRestartStateless | 
      .1.3.6.1.4.1.9.9.305.1.3.3 | 
    
    
      | 
        Tells if the most recent restart of a service on the
        'active' supervisor was 'stateless' or not.
        A 'stateless' restart of a service is where no runtime
        information is preserved while restarting the service.
       | 
    
    
      | cseHaRestartService | 
      .1.3.6.1.4.1.9.9.305.1.3.4 | 
    
    
      | 
        Name of the service (or process) that was restarted on
        the 'active' supervisor.
       | 
    
  
  
    
      | Tabular Object | 
    
  
  
    
      | cseSnmpErrorAddressType | 
      .1.3.6.1.4.1.9.9.305.1.2.1.1.1 | 
    
    
      | 
        The type of address from which the error-ed SetRequest
        originated.
       | 
    
    
      | cseSnmpErrorAddress | 
      .1.3.6.1.4.1.9.9.305.1.2.1.1.2 | 
    
    
      | 
        The address from which the error-ed SetRequest originated.
       | 
    
    
      | cseSnmpErrorRequestId | 
      .1.3.6.1.4.1.9.9.305.1.2.1.1.3 | 
    
    
      | 
        The request-id of the error-ed SetRequest.
       | 
    
    
      | cseSnmpErrorCode | 
      .1.3.6.1.4.1.9.9.305.1.2.1.1.4 | 
    
    
      | 
        The code for the Mib object specific error which
        caused a SetRequest to fail.
        This error code is platform-specific and for debugging
        purposes only. For information on this code, the
        corresponding instance of cseSnmpErrorDescription must be
        used.
        This code is not the same as the value contained
        in the error-status field of SNMP Response PDU.
       | 
    
    
      | cseSnmpErrorDescription | 
      .1.3.6.1.4.1.9.9.305.1.2.1.1.5 | 
    
    
      | 
        The error description for the error happened for the
        SetRequest.
       | 
    
  
  
    
      | Table | 
    
  
  
    
      | cseSnmpErrorTable | 
      .1.3.6.1.4.1.9.9.305.1.2.1 | 
    
    
      | 
        A table containing information about the errors which have
        recently caused the generation of a SNMP Response PDU with a
        non-zero value in its error-status field for SNMP Set Response
        PDU.
        This table serves as an extension to the SNMP's error status
        when a SNMP Set request fails. SNMP returns only a pre-defined
        set of standard error codes which does not convey the specific
        cause for an error. Typically, there is an incumbent and
        sizable burden on the configuration application to determine
        if the configuration request failure is the result of a
        resource issue, a security issue, or an application error
        (like an object depending on some other objects). So from a
        user perspective, it is important that a specific error be
        made known.
        Ideally, when a 'badValue' error occurs for a given set
        request, an application can query the command responder for
        more details on the error.
        This table provides a framework for the command responders to
        provide more information on the SET errors.
        It is upto the implementation to create entries in this table
        for either only certain SNMP errors or all of the SNMP errors.
        Note that only most recent incarnation of an entry is kept in
        this table.

        A service restart notification is generated
        whenever a service (or a process) on the  'active'
        supervisor is restarted.
