11.8 Technical Reference
This section provides some technical background information about the topics covered in this
chapter.
11.8.1 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.
11.8.2 Supported MIBs
The ZyXEL Device 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.
11.8.3 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 ZyXEL Device can send the following traps to the SNMP manager.
