An agent is a management software module that resides in a managed device (the ZyXEL
Device). An agent translates the local management information from the managed device into
a form compatible with SNMP. The manager is the console through which network
administrators perform network management functions. It executes applications that control
and monitor managed devices.
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.
11.6.1 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.
11.6.2 SNMP Traps
The ZyXEL Device can send the following traps to the SNMP manager.
