13.6 Configuring SNMP

Simple Network Management Protocol is a protocol used for exchanging management information

between network devices. SNMP is a member of the TCP/IP protocol suite. Your 1500WR Wireless

Router supports SNMP agent functionality, which allows a manager station to manage and monitor the

1500WR Wireless Router through the network. The 1500WR Wireless Router supports SNMP version

one (SNMPvl) and version two c (SNMPv2c).

The next figure illustrates an SNMP management operation. SNMP is only available if TCP/IP is

configured.

An SNMP managed network consists of

two main types of component: agents and a

manager.

An agent is a management software

module that resides in a managed device

(the 1500WR Wireless Router). An agent

translates the local management information

from the managed device into a form

compatible with SNMP

is the console through which network

. The manager

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

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 SNMPvl, 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.

13.6.1 Supported MIBs

The 1500WR Wireless Router supports MIB II that is defined in RFC-1213 and RFC-1215. The focus of

the MIBs is to let administrators collect statistical data and monitor status and performance.

13.6.2 SNMP Traps

The 1500WR Wireless Router will send traps to the SNMP manager when any one of the following

events occurs:

SNMP Traps
