5、Protocol Management Information Base RDD 4-2005 Page 2 of 44 pages 1 Scope This document defines a Management Information Base (MIB) for Professional AV products as Pro-AV MIB-1 based upon Sony implementations. The MIB defines the items managed by the Simple Network Management Protocol (SNMP) and co

6、mprises variables that maintain the status of equipment. Provisions of the Pro-AV MIB-1 provides capability for any company to create a private node, contents can be individually managed by that company. 2 Normative references RFC 1155, Structure and Identification of Management Information for TCP/

9、 the network management functions requested by network management stations. An agent module may be implemented in any network element that is to be managed, such as a host, bridge, or router. Agents and network management stations communicate by means of SNMP. 3.2 Management Information Base (MIB):

10、In the context of SNMP, this term is used in two contexts: (1) A structured set of data variables, called objects, in which each variable represents some resource to be managed. Each agent in a network maintains a MIB for the network element on which it executes. (2) The definition of a related coll

11、ection of objects that represent some related collection of resources to be managed. 3.3 Object: A data variable that represents some resource or other aspect of a managed device; also referred to as a managed object. 3.4 Object Identifier (OID): Uniquely identifies an object within a MIB. The form

12、of an object identifier is a sequence of numbers separated by periods. This sequence defines the location of an object in the tree-structured MIB of which it is a part. 3.5 Trap: An unsolicited message sent by an agent to a management station. The purpose is to notify the management station of some

13、unusual event. RDD 4-2005 Page 3 of 44 pages 4 Pro-AV MIB-1 Overview Pro-AV MIB-1 has a structure that can support monitoring of various products. Also, items and structures are simplified as much as possible in order to be able to easily implement for various categories of products. The Structure o

14、f Management Information (SMI) for the MIB definitions shall comply with RFC 2578 (SMIv2). The items composing the MIB should be grouped so that they can be managed in three sets of information as follows: Common information Category common information Individual product information This document de

15、fines the common information. NOTE This MIB can be applied under each individual company ID, after setting an appropriate OID number for Pro-AV MIB-1 in parallel to existing OIDs under the company OID. 5 Pro-AV MIB-1 Structure The composition of Pro-AV MIB-1 structure shall be as follows. Figure 1 P

16、ro-AV MIB-1 Overall Structure 5.1 Common Definitions (proV1MIB) Definitions commonly used in “Common MIB“, “Category MIB“ and “Product MIB“ shall be entered. Consequently, the “TEXTUAL-CONVENTION“ macro defining data expression is entered. This is not implemented as objects, but provided separately

17、as a MIB definition file. An OID shall be given to the module as a Module Identifier by the rule of SMI.

The product ID information (including module information), information concerning the SNMP agent, error tabl

19、e, and trap definitions shall be included in the Common MIB. Figure 2 Common MIB (proV1Common) Structure 5.3 Category MIB (proV1Category) The common variable items for each category are defined in the Category MIB. When a new Category MIB is created, it shall be added positioned below this proV1Cate

20、gory. This shall be individually defined and managed by each company. 5.4 Product MIB (proV1Product) The variable items for each product are defined in the Product MIB. Product MIBs shall be prepared when defining variable items unique to a product that are not defined by the Common MIB or Category

21、MIB. When a new Product MIB is created, it is added below this proV1Product. This shall be individually defined and managed by each company. 6 Individual items in Common Definitions The Common Definitions contain definitions of information common to the “Common MIB“, “Category MIB“, and “Product MIB

22、 Consequently, the “TEXTUAL-CONVENTION“ macro defining data expression is entered. The TEXTUAL CONVENTION is a macro used to clearly express data for which the meaning may be different even though the data type is the same. For example, when there are frequencies and cycle times as numerical infor

23、mation, both may be expressed as integers, but the values shall have different meanings for each type. The following TEXTUAL CONVENTION shall be defined for such purposes as clarifying these differences. (1) Local time This expresses the local time information as a character string with the format “

24、YYYY/MM/DD hh:mm:ss:ff GMT+HH:MM“. The ff positioned after the seconds (ss) expresses the frame number, and proV1Common(2) proV1Category(3) proV1Product(4) proV1ProductInfo proV1AgentInfo proV1ErrorStatus proV1Trap Common MIB Pro-AV MIB-1 (xxxx) proV1MIB(1) SNMP Agent Information Error Status Tables

(2) Cycle time This expresses a cycle time as an integer in the range 0-2147483647. (3) Frequency This expresses

26、a frequency as an integer in the range 0-2147483647. (4) Scanning line number This expresses the scanning line number as an integer in the range 0-2147483647. (5) Frame number This expresses the frame number as an integer in the range 0-2147483647. ProV1TimeStamp := TEXTUAL-CONVENTION STATUS current
