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.
15.9.1 Supported MIBs
The NWA3000-N series AP supports MIB II that is defined in RFC-1213 and RFC-
1215. The NWA3000-N series AP also supports private MIBs (ZYXEL-ES-
CAPWAP.MIB, ZYXEL-ES-COMMON.MIB, ZYXEL-ES-HYBRIDAP.MIB, ZYXEL-ES-
PROWLAN.MIB, ZYXEL-ES-RFMGMT.MIB, ZYXEL-ES-SMI.MIB, and ZYXEL-ES-
WIRELESS.MIB) to collect information about CPU and memory usage and VPN
total throughput. The focus of the MIBs is to let administrators collect statistical
data and monitor status and performance. You can download the NWA3000-N
series AP’s MIBs from www.zyxel.com.
15.9.2 SNMP Traps
The NWA3000-N series AP will send traps to the SNMP manager when any one of
