23-2 SNMP Configuration
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:
Table 23-1 SNMP Commands
COMMAND DESCRIPTION
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.
23.2 Supported MIBs
VLC1012 supports MIB II (defined in RFC-1213 and RFC-1215). The VLC1012 can also respond with specific
data from the ZyXEL private MIBs (zyxel.mib and zyxel-AS.mib). MIBs let administrators collect statistics and
monitor status and performance.
23.3 Configuring SNMP
To configure SNMP, enter 22 from the main menu to open Menu 22 — SNMP Configuration , as shown in the
next figure. The “community” for Get , Set and Trap fields is simply SNMP’s terminology for password.
