Chapter 28 SNMP 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 the 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.
28.2   Supported MIBs
The Prestige supports RFC-1215 and MIB II as defined in RFC-1213 as well as ZyXEL 
private MIBs. The focus of the MIBs is to let administrators collect statistic data and monitor 
status and performance.
28.3  SNMP Configuration
To configure SNMP, select option 22 from the main menu to open Menu 22 — SNMP 
Configuration 
as shown next.  The “community” for Get, Set and Trap fields is SNMP 
terminology for password.
