30.1 SNMP Overview
This screen allows you to configure the SNMP settings on the Zyxel Device.
The Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your Zyxel Device supports SNMP agent functionality, which allows a
manager station to manage and monitor the Zyxel Device through the network. The next figure
illustrates an SNMP management operation.
Figure 162 SNMP Management Model
An SNMP managed network consists of two main types of components: agents and a manager.
An agent is a management software module that resides in a managed device (the Zyxel Device). An
agent translates the local management information from the managed device into a form compatible
with SNMP. The manager is the console through which network administrators perform network
management functions. It executes applications that control and monitor managed devices.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a device. Examples of variables include the number of packets
received, node port status, and so on. A Management Information Base (MIB) is a collection of
managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing
these objects.
