Community is a String property that repesents the SNMP community name required to build an SNMP message. A pairing of an SNMP agent with some arbitrary set of SNMP application entities is called an SNMP community. 

Community is the value read from and/or written to ASN.1-encoded messages as represented in TSNMPInfo in the SendQuery or SendTrap methods. 

The default value for Community is 'public', as assigned during initialization of the component. 

Use Query, Reply, and Trap to access property values for objects in the Management Information Base (or MIB).
