SNMP
25.1 SNMP Agent
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your Router supports SNMP agent functionality, which allows a manager
station to manage and monitor the Router through the network. The Router supports SNMP
version one (SNMPv1) and version two (SNMPv2c). The next figure illustrates an SNMP management
operation.
Figure 127 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 Router). 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.
