33.10 SNMP
Simple Network Management Protocol is a protocol used for exchanging
management information between network devices. Your NXC supports SNMP
agent functionality, which allows a manager station to manage and monitor the
NXC through the network. The NXC 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
NXC). 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.
