SNMP-TARGET-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.

Copyright (C) The Internet Society (2002). This version of this MIB module is part of RFC 3413; see the RFC itself for full legal notices. " REVISION "200210140000Z" -- 14 October 2002 DESCRIPTION "Fixed DISPLAY-HINTS for UTF-8 strings, fixed hex value of LF characters, clarified meaning of zero length tag values, improved tag list examples. Published as RFC 3413." REVISION "199808040000Z" -- 4 August 1998 DESCRIPTION "Clarifications, published as RFC 2573."

Tag values are preferably in human-readable form. To facilitate internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using the UTF-8 character encoding scheme described in RFC 2279. Since additional code points are added by amendments to the 10646 standard from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. The use of control codes should be avoided, and certain control codes are not allowed as described below. For code points not directly supported by user interface hardware or software, an alternative means of entry and display, such as hexadecimal, may be provided. For information encoded in 7-bit US-ASCII, the UTF-8 representation is identical to the US-ASCII encoding. Note that when this TC is used for an object that is used or envisioned to be used as an index, then a SIZE restriction must be specified so that the number of sub-identifiers for any object instance does not exceed the limit of 128, as defined by [RFC1905]. An object of this type contains a single tag value which is used to select a set of entries in a table. A tag value is an arbitrary string of octets, but may not contain a delimiter character. Delimiter characters are defined to be one of the following: - An ASCII space character (0x20). - An ASCII TAB character (0x09). - An ASCII carriage return (CR) character (0x0D). - An ASCII line feed (LF) character (0x0A). Delimiter characters are used to separate tag values in a tag list. An object of this type may only contain a single tag value, and so delimiter characters are not allowed in a value of this type. Note that a tag value of 0 length means that no tag is defined. In other words, a tag value of 0 length would never match anything in a tag list, and would never select any table entries. Some examples of valid tag values are: - 'acme' - 'router' - 'host' The use of a tag value to select table entries is application and MIB specific."

Delimiter characters are used to separate tag values in a tag list. Only a single delimiter character may occur between two tag values. A tag value may not have a zero length. These constraints imply certain restrictions on the contents of this object: - There cannot be a leading or trailing delimiter character. - There cannot be multiple adjacent delimiter characters. Some examples of valid tag lists are: - '' -- an empty list - 'acme' -- list of one tag - 'host router bridge' -- list of several tags Note that although a tag value may not have a length of zero, an empty string is still valid. This indicates an empty list (i.e. there are no tag values in the list). The use of the tag list to select table entries is application and MIB specific. Typically, an application will provide one or more tag values, and any entry which contains some combination of these tag values will be selected." SYNTAX OCTET STRING (SIZE (0..255)) -- -- -- The snmpTargetObjects group -- -- snmpTargetSpinLock OBJECT-TYPE SYNTAX TestAndIncr MAX-ACCESS read-write STATUS current DESCRIPTION "This object is used to facilitate modification of table entries in the SNMP-TARGET-MIB module by multiple managers. In particular, it is useful when modifying the value of the snmpTargetAddrTagList object. The procedure for modifying the snmpTargetAddrTagList object is as follows: 1. Retrieve the value of snmpTargetSpinLock and of snmpTargetAddrTagList. 2. Generate a new value for snmpTargetAddrTagList. 3. Set the value of snmpTargetSpinLock to the retrieved value, and the value of snmpTargetAddrTagList to the new value. If the set fails for the snmpTargetSpinLock object, go back to step 1." ::= { snmpTargetObjects 1 } snmpTargetAddrTable OBJECT-TYPE SYNTAX SEQUENCE OF SnmpTargetAddrEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A table of transport addresses to be used in the generation of SNMP messages." ::= { snmpTargetObjects 2 } snmpTargetAddrEntry OBJECT-TYPE SYNTAX SnmpTargetAddrEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A transport address to be used in the generation of SNMP operations.

The format of this address depends on the value of the snmpTargetAddrTDomain object." ::= { snmpTargetAddrEntry 3 } snmpTargetAddrTimeout OBJECT-TYPE SYNTAX TimeInterval MAX-ACCESS read-create STATUS current DESCRIPTION "This object should reflect the expected maximum round trip time for communicating with the transport address defined by this row. When a message is sent to this address, and a response (if one is expected) is not received within this time period, an implementation may assume that the response will not be delivered. Note that the time interval that an application waits for a response may actually be derived from the value of this object. The method for deriving the actual time interval is implementation dependent. One such method is to derive the expected round trip time based on a particular retransmission algorithm and on the number of timeouts which have occurred. The type of message may also be considered when deriving expected round trip times for retransmissions. For example, if a message is being sent with a securityLevel that indicates both authentication and privacy, the derived value may be increased to compensate for extra processing time spent during authentication and encryption processing."
