16.6 Technical Reference
This section provides some technical background information about the topics
covered in this chapter.
16.6.1 MIB
Managed devices in an SMNP managed network contain object variables or
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 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.
16.6.2 Supported MIBs
The NWA supports MIB II that is defined in RFC-1213 and RFC-1215 as well as the
proprietary ZyXEL private MIB. The purpose of the MIBs is to let administrators
collect statistical data and monitor status and performance.
16.6.3 SNMP Traps
SNMP traps are messages sent by the agents of each managed device to the
SNMP manager. These messages inform the administrator of events in data
networks handled by the device. The NWA can send the following traps to the
SNMP manager.
