31.1 About 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 Prestige supports
SNMP agent functionality, which allows a manager station to manage and monitor the Prestige
through the network. The Prestige supports SNMP version one (SNMPv1) and version two c
(SNMPv2c). The next figure illustrates an SNMP management operation. SNMP is only available if
TCP/IP is configured.

Figure 31-1 SNMP Management Model
An SNMP managed network consists of two main components: agents and a manager.
An agent is a management software module that resides in a managed device (the Prestige). 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 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.

SNMP itself is a simple request/response protocol based on the manager/agent model. The manager
issues a request and the agent returns responses using the following protocol operations:
