I am totally new to mib and i have read about snmp on techdive and get the basic understanding of SNMP4J can anyone tell me how to use MIB in snmp4j ? Thank in Advance
Sure. You basically query a client for information giving an OID for the field in the MIB you require.
A basic sample taken from the referenced blog is:
PDU request = new PDU();
request.setType(PDU.GET);
OID oid= new OID("1.3.6.1.2.1.1.1.0");
request.add(new VariableBinding(oid));

Here is the java doc for the OID: http://www.snmp4j.org/doc/org/snmp4j/smi/OID.html
