Chapter 15 Remote Management Configuration
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.
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.

15.6.1 Supported MIBs

The ZyXEL Device 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.

15.6.2 SNMP Traps

The ZyXEL Device will send traps to the SNMP manager when any one of the following
events occurs:

A trap is sent after booting (power on).
A trap is sent after booting (software reboot).
A trap is sent with the reason of restart before
rebooting when the system is going to restart (warm
start).
A trap is sent with the message "System reboot by

download new files, CI command "sys reboot", etc.).
A trap is sent with the message of the fatal code if the
system reboots because of fatal errors.
