SNMP Operations
SNMP itself is a simple request/response protocol. NMSs can send multiple requests without receiving a response.
 Get -- Allows the NMS to retrieve an object instance from the agent.
 Set -- Allows the NMS to set values for object instances within an agent.
 Trap -- Used by the agent to asynchronously inform the NMS of some event. The SNMPv2 trap message is
designed to replace the SNMPv1 trap message.
SNMP community
An SNMP community is the group that devices and management stations running SNMP belong to. It helps define where
information is sent. The community name is used to identify the group. A SNMP device or agent may belong to more than
one SNMP community. It will not respond to requests from management stations that do not belong to one of its
communities. The normal SNMP default communities are as below when configured:
 Write = private
Read = public

permitted as part of a name. The first character must be an alpha character. And
the first or last character must not be a minus sign.
The allowed string length is 0 to 255.
