CISCO-SYSTEM-EXT-MIB device MIB details by Cisco

CISCO-SYSTEM-EXT-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
         "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."
