11-2 SNMP Configuration
Management Information Base (MIB) is a collection of managed objects. SNMP allows 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.
11.2 Supported MIBs
The P1600 supports MIB II that is defined in RFC-1213 and RFC-1215. The P1600 can also respond with specific
data from the ZyXEL private MIB (ZYXEL-MIB). The focus of the MIBs is to let administrators collect statistic
data and monitor status and performance.
The only implement MIBs in P1600 as a SNMP agent. Users must implement their own GUI on SNMP platform
(SNMP manager).
When the user logs in using SMT, the set-request will be ignored for the protection of data.
11.3 SNMP Configuration
To configure SNMP, select option 22 from the Main Menu to open Menu 22 - SNMP Configuration as shown
