SNMP Configuration  

       31-1 

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. 

 

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:
