Chapter 25: Managing the Network From
a Management Station (NMS)
SNMPv2 (Simple Network Management Protocol Version 2) can be used to manage and monitor
the modules under SMI (Structure of Management Information) specifications. SMI specifies
management information definitions in ASN.1 (Abstract Syntax Notation One) language.
SNMPv2 supports both 32-bit and 64-bit counters. The SMI for SNMPv2 is defined in RFC 1902
at http://www.faqs.org/rfcs/rfc1902.html
.
Roles of Hardware and Software Elements
Role of the Agent
In SNMP, software on each managed device acts as the agent. The agent collects and stores
management information in ASN.1 format, in a structure that a MIB (management information
base) defines. The agent responds to commands to
• send information about the managed device.
• modify specific data on the managed device.
Role of the Managed Device
In SNMP, the managed device is the network element that operates on the agent software. In the
fixed wireless broadband IP network, this managed device is the module (AP, SM, or BH). With
the agent software, the managed device has the role of server in the context of network
management.
Role of the NMS
In SNMP, the NMS (network management station) has the role of client. An application (manager
software) operates on the NMS to manage and monitor the modules in the network through
interface with the agents.
