15.1 About SNMP
Simple Network Management Protocol is a protocol used for exchanging management information between
network devices. SNMP is a member of 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). The next figure illustrates an SNMP management
operation. SNMP is only available if TCP/IP is configured.
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 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.
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:
