RFC 1298 – SNMP over IPX (SNMP, Part 1 of 2, I.1.)

The first protocol developed was the Simple Network Management Protocol

(SNMP). It was commonly considered to be a quickly designed “band-aid” solution

to internetwork management difficulties while other, larger and better protocols

were being designed. (Miller, 46). However, no better choice became available,

and SNMP soon became the network management protocol of choice.

It works very simply (as the name suggests): it exchanges network packets

through messages (known as protocol data units (PDU)). The PDU contains

variables that have both titles and values. There are five types of PDU’s

which SNMP uses to monitor a network: two deal with reading terminal data, two

with setting terminal data, and one called the trap, used for monitoring network

events, such as terminal start-ups or shut-downs.

By far the largest advantage of SNMP over CMIP is that its design is simple,

so it is as easy to use on a small network as well as on a large one, with ease

of setup, and lack of stress on system resources. Also, the simple design makes

it simple for the user to program system variables that they would like to

monitor. Another major advantage to SNMP is that is in wide use today around

the world. Because of it’s development during a time when no other protocol of

this type existed, it became very popular, and is a built in protocol supported
