function, you do not need to know the exact variable name you are looking for. 
The SNMP manager takes the variable you name and then uses a sequential 
search to find the desired variable.
Retrieve a number of values – a get-bulk action
The SNMP manager performs the number of get-next actions that you specify.
Change a setting on the agent – a set action
The SNMP manager requests the agent to change the value of the MIB variable. 
For example, you can run a script or an application on a remote device with a 
set action.
An agent can send an unsolicited message to the manager at any time if a 
significant, predetermined event takes place on the agent. This message is called 
trap
When a trap condition occurs, the SNMP agent sends an SNMP trap message to 
the device specified as the trap receiver or trap host. The SNMP Administrator 
configures the trap host, usually the SNMP management station, to perform the 
action needed when a trap is detected. 
SNMP Communities
Each SNMP device or member is part of a community. An SNMP community 
determines the access rights for SNMP devices. 
You supply a name to the community. After that, all SNMP devices that are 
assigned to that community as members have the same access rights. The access 
rights are:
read
 - Allows read-only access to the MIB tree for devices included in this 
community 
read-write
 - Allows both read and write access to the MIB tree for devices 
included in this community
trap
 – Allows traps to be sent between devices included in this community
