SNMP初涉备忘(For Windows2003)

1、安装Windows2003的SNMP组件
2、在服务->SNMP Service->陷阱 中增加一个团体名称public
3、增加陷阱目标127.0.0.1
4、在安全中，增加一个“接受团体名称”，把public加入进去
5、下载snmp4j.jar后(依赖包见附件)，测试的Java代码如下

package nj.snmpstudy;

import java.io.IOException;
import java.util.Vector;
import org.snmp4j.CommunityTarget;
import org.snmp4j.PDU;
import org.snmp4j.Snmp;
import org.snmp4j.TransportMapping;
import org.snmp4j.event.ResponseEvent;
import org.snmp4j.mp.SnmpConstants;
import org.snmp4j.smi.Address;
import org.snmp4j.smi.GenericAddress;
import org.snmp4j.smi.OID;
import org.snmp4j.smi.OctetString;
import org.snmp4j.smi.VariableBinding;
import org.snmp4j.transport.DefaultUdpTransportMapping;

public class First {
	private Snmp snmp = null;

	private Address targetAddress = null;

	public void initComm() throws IOException {

		// 设置Agent方的IP和端口
		targetAddress = GenericAddress.parse("udp:127.0.0.1/161");
		TransportMapping transport = new DefaultUdpTransportMapping();
		snmp = new Snmp(transport);
		transport.listen();

	}

	public void sendPDU() throws IOException {

		// 设置 target
		CommunityTarget target = new CommunityTarget();
		target.setCommunity(new OctetString("public"));
		target.setAddress(targetAddress);

		// 通信不成功时的重试次数
		target.setRetries(2);

		// 超时时间
		target.setTimeout(1500);
		target.setVersion(SnmpConstants.version1);

		// 创建 PDU
		PDU pdu = new PDU();
		
		pdu.add(new VariableBinding(new OID(new int[] { 1, 3, 6, 1, 2, 1, 1, 5, 0 })));
		//pdu.add(new VariableBinding(new OID(new int[] {1,3,6,1,2,1,25,3,3,1,2,2})));
		//pdu.add(new VariableBinding(new OID(new int[] {1,3,6,1,2,1,25,2,1,2})));
		
		//pdu.add(new VariableBinding(new OID(new int[] {1,3,6,1,2,1,1,8,0})));
		
		// MIB的访问方式
		pdu.setType(PDU.GET);

		// 向Agent发送PDU，并接收Response
		ResponseEvent respEvnt = snmp.send(pdu, target);

		// 解析Response
		System.out.println("解析Response");
		if (respEvnt != null && respEvnt.getResponse() != null) {
			Vector<VariableBinding> recVBs = respEvnt.getResponse().getVariableBindings();
			for (int i = 0; i < recVBs.size(); i++) {
				VariableBinding recVB = recVBs.elementAt(i);
				System.out.println(recVB.getOid() + " : " + recVB.getVariable());
			}

		}

	}

	public static void main(String[] args) {
		try {
			First util = new First();
			util.initComm();
			util.sendPDU();
		} catch (IOException e) {
			e.printStackTrace();
		}

	}
}

6、执行结果为：
解析Response
