SNMP

Short for Simple Network Management Protocol, a set of protocols for managing complex

networks. SNMP works by sending messages, called protocol data units (PDUs), to different parts

of a network. SNMP-compliant devices, called agents, store data about themselves in Management

Information Bases (MIBs) and return this data to the SNMP requesters.

5.7.1 SNMP Community

SNMP Community provides a simple kind of password protection. Access to the SNMP

device is controlled through community names. The community name can be thought of as a

password. If you don’t have the correct community name you can’t retrieve any data (get) or make

any changes (sets). Multiple SNMP managers may be organized in a specified community. You can

change your SNMP community settings on this screen. Check the “Enable” check box to enable the

SNMP function. Click

APPLY

to complete your change.

Validity:

You can enable or disable the SNMP function of the corresponding community item.

Access Right:

Select a access right for the corresponding SNMP community

(Deny

4

/Read

5

/Write

).

Community:

Specify the name of community for the SNMP manager( Private/Public). By

convention, “Public” community is with a read-only access right.

4

Deny community will not allow a remote device to read information from a device or to modify settings on that

device.

5

Read-only community enables a remote device to retrieve "read-only" information from a device.

6

Read-Write community allows a remote device to read information from a device and to modify settings on that

device.

SNMP TRAP message can be sent to a host. Click

APPLY

to complete your settings.

Version

: Select the SNMP Version.

Select “Disable” to disable the snmp trap function of the corresponding item.

Version1: SNMP Version1

Version2: SNMP Version2

IP Address:

Specify the IP Address of the SNMP Manager for SNMP Trap Report.

Community:

Specify the name of community ( public/Private) for SNMP manager.

Following are the traps supported in the access point:

Cold-start trap:

This trap indicates that the specified node’s power has just come on. The cold-start trap is

generated every time the access point is power-cycled. Cold-start traps are not generated

until three seconds after the access point is power-cycled. This allows time for the hardware

providing the low-level IP network interface to start up and stabilize before attempting to

send a packet.
