9.1 BASICS
The AireLink™ system supports the Simple Network Management Protocol (SNMP), an Internet-
standard protocol for managing devices on IP networks. The system supports SNMP v.1 & SNMP v.2c
versions. In typical SNMP implementations, one or more administrative computers, called managers,
have the task of monitoring or managing a group of hosts or devices such as the AireLink™ system on
a computer network. Each managed system executes, at all times, a software component called an
agent which reports information via SNMP to the manager. An agent is a network-management
software module that resides on a managed device such as the AireLink™ system. The agent has local
knowledge of management information and translates that information to or from an SNMP specific
form. SNMP itself does not define which information/variables a managed system should offer. Rather,
SNMP uses an extensible design, where the available information is defined by management
information bases (MIBs). MIBs describe the structure of the management data of a device subsystem;
they use a hierarchical namespace containing object identifiers (OID). Each OID identifies a variable
that can be read or set via SNMP. For the SNMP system to function properly, the MIBs of monitored
components must be compiled into an SNMP Management System such as NET-SNMP, HP OPENVIEW,
SNMPC or similar commercially available programs. For illustrative purposes we are using the MG-
SOFT Software
9.2 LightPointe MIB Files
LightPointe provides a MIB named LPCOMM-MIB to monitor the AireLink™ wireless point to point
communication systems. The MIB must be compiled into the management system using the
appropriate compiler function. After the MIB is compiled correctly, it must both show as part of the
loaded MIB modules. See the example in Figure 9-1 below.
