The SNMP Screen
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your AMG1302/AMG1202-TSeries supports SNMP agent functionality,
which allows a manager station to manage and monitor the AMG1302/AMG1202-TSeries through
the network. The AMG1302/AMG1202-TSeries supports SNMP version one (SNMPv1) and version
two (SNMPv2c). The next figure illustrates an SNMP management operation.

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 AMG1302/
AMG1202-TSeries). 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.
