Chapter 18 The Remote Management Screens
User’s Guide
208
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.
The WiMAX Modem supports MIB II that is defined in RFC-1213 and RFC-1215.
The focus of the MIBs is to let administrators collect statistical data and monitor
status and performance.
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:
• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table
or list within an agent. In SNMPv1, when a manager wants to retrieve all
elements of a table from an agent, it initiates a Get operation, followed by a
series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.
18.5.1 SNMP Traps
The WiMAX Modem sends traps to the SNMP manager when any of the following
events occurs:
