CISCO-DEVICE-EXCEPTION-REPORTING-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

    DESCRIPTION
        "This mib defines the SNMP objects to report
         exceptions to north-bound NMS.

         The devices implementing this MIB monitor 
         the status of hardware and software services, and
         report any exceptions regarding these components.
         These hardware and software services could 
         belong to the monitoring devices or other managed
         devices. 

         An exception is something abnormal that the system 
         administrators should pay attention to. The criteria
         for what is an exception could vary by system
         and should be defined by the system administrators.
         Certain NM devices or applications may have 
         pre-defined exceptions. 

         This MIB does not try to define exceptions. But 
         rather it defines SNMP objects for devices to 
         use SNMP notification as an exception reporting 
         mechanism. Exceptions may be pre-defined or defined 
         through other device management interface such as 
         CLI, GUI, or HTTP."

         the old records on a first-in-first-out

         If a NMS is receiving notifications, 
         it can periodically poll this object 
         to find out if any notifications were 
         missed. In that case it could poll

         If the difference between two consecutive 
         polls of this object is greater than 
         cderMaxExceptionRecords, then it indicates
         the NMS will not be able to find missing 
         exceptions. The solution is to either poll 
         the cderExceptionTable more frequently
