T1: A Survival Guide

SNMP

SNMP by itself is a wide topic. Only a few T1-specific RFCs were presented in detail in this book. For interested readers, this reference list includes the earlier documents that laid out the specifications for SNMP itself.

SNMP Foundations

RFC 1157

“Simple Network Management Protocol (SNMP)”

This is the first version of the SNMP wire protocol. It includes the ill-fated “security” based on community strings.

RFC 1155

“Structure and Identification of Management Information for TCP/IP-based Internets”

SNMP lays out data in a highly structured format, referred to as the Structure of Management Information (SMI). This RFC defines the basic data types used by SNMP MIBs.

ISO 8824

“Information technology—Open Systems Interconnection—Specification of Abstract Syntax Notation One (ASN.1)”

ASN.1 is a rigorous syntax for describing structured data. ASN.1 is the language of SNMP because the MIBs are defined using ASN.1 syntax.

RFC 1213

“Management Information Base for Network Management of TCP/IP-based Internets: MIB-II”

Basic system information is contained in MIB-2. Among other things, MIB-2 contains the interfaces table to which the DS1 and frame relay DTE MIBs cross-index.

SNMP Version 2

SNMPv2 provided several enhancements over the initial SNMP standards. It made tables easier to work with, expanded the data types available to MIB authors, and improved the efficiency of the protocol. Its major failing was in not improving the “security” model of SNMPv1.

RFC 2578
