1. Concepts SNMP is a standard protocol used to manage network nodes (servers, workstations, routers, switches, and HUBS) in an IP network. It is an application layer protocol. SNMP enables network administrators to manage network performance, discover and solve network problems, and plan network growth. The Network Management System receives random messages (and event reports) through

Many people think that SNMP is running on IP because the Internet is running the TCP/IP protocol, but that is not the case.SNMP is designed to be protocol-independent, so it can be used on Ip,ipx,appletalk,osi and other transport protocols used.SNMP is a series of protocol groups and specifications

The advantage is that you do not need to modify the configuration file. The disadvantage is that you have to re-compile each addition. 2. dynamically load the g

30.10SNMP Message Format　　Unlike most TCP/IP protocols, SNMP messages does not have a fixed fields. Instead, they use the standard ASN.1 encoding. Thus, a message can be difficult for humans to decode and understand. After examining the SNMP message definition in ASN.1 notation, we'll review the ASN.L encoding scheme briefly, and see a n example of an encoded SNMP
