15.6 SNMP
Simple Network Management Protocol (SNMP) 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 (SNMPv2). The next figure illustrates an SNMP
management operation. SNMP is only available if TCP/IP is configured.
Note: SNMP is only available if TCP/IP is configured.
Figure 90 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 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.
