3.2 Using SNMP
SNMP Simple Network Management Protocol) is part of the TCP/IP networking suite. It
allows a network administrator to remotely collect information about devices on the network,
and make changes to their configuration. This tutorial is an example of using SNMP to
monitor and manage a ZyXEL Device.
3.2.1 Requirements
In SNMP architecture, devices that issue requests for information are known as managers, and
devices that provide information are known as agents. Agents can provide data to a manager
either reactively (in response to a request) or autonomously (in the case of an alert). Each
agent possesses a set of information types about which it can provide data, which is
collectively known as a Management Information Base, or MIB.
To use SNMP on your network, you must obtain management software capable of issuing
SNMP requests and displaying the returned responses. Many third-party SNMP managers
exist, each of which is operated and displays information differently. However, the foundation
upon which each is based is exactly the same.
"
This example uses SNMP Manager (v1.0.1.30) software manufactured by
AdRem Software. It is presented in order to illustrate the capabilites of SNMP
in conjunction with your ZyXEL device, but is NOT specifically a guide to using
ZyXEL systems.
3.2.2 Discovering Your Device
When you use the SNMP manager for the first time, or add a new device to your network, you
must either scan the network for SNMP-capable devices (“nodes”) or specify each individual
device’s IP address. In this example, you will scan for nodes.
