IPMROUTE-STD-MIB device MIB details by RFC

IPMROUTE-STD-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.

            "An RFC 1766-style language tag, with all alphabetic
            characters converted to lowercase.  This restriction is
            intended to make the lexical ordering imposed by SNMP useful

            when applied to language tags.  Note that it is
            theoretically possible for a valid language tag to exceed
            the allowed length of this syntax, and thus be impossible to
            represent with this syntax.  Sampling of language tags in
            current use on the Internet suggests that this limit does
            not pose a serious problem in practice."
