Network Management Using SNMP

1. SNMP Overview
Simple Network Management Protocol
information between network devices (such as routers and switches). By using SNMP, network administrators
can easily monitor network devices, detect and solve network problems. SNMP is a member of the TCP/IP
protocol suite and it uses the UDP to exchange messages between a management Client and an Agent, residing
in a network node.
There are two versions of SNMP: Version 1 and Version 2. ZyXEL supports SNMPv1. Most of the changes
introduced in Version 2 enhance SNMP's security capabilities. SNMP encompasses three main areas:
1. A small set of management operations.
2. Definitions of management variables.
3. Data representation.
Operations allowed are: Get, GetNext, Set, and Trap. These functions operate based on variables stored on
network nodes. Examples of variables include statistic counters and node port status. All SNMP management
functions are carried out through these simple operations. No action operations are available, but these can be
simulated by the setting the variable flags. For example, to reset a node, a counter variable called 'time to reset'
can be set to a value which causes the node to reset after the time had elapsed.
