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
6
).
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.

to complete your settings.
Version

Select “Disable” to disable the snmp trap function of the corresponding item.
Version1: SNMP Version1

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.
