16.2 SNMP
Simple Network Management Protocol is a protocol used for exchanging management
information between network devices. SNMP is a member of the TCP/IP protocol suite. Your
ZyXEL Device supports SNMP agent functionality, which allows a manager station to
manage and monitor the ZyXEL Device through the network. The ZyXEL Device supports
SNMP version one (SNMPv1). The next figure illustrates an SNMP management operation.
SNMP is only available if TCP/IP is configured.

Figure 84 SNMP Management Model
An SNMP managed network consists of two main types of component: 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 such as number of
packets received, node port status etc. 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.
