snmp4j 过滤错误的节点

1.主要代码如下： 开发包（snmp4j.jar）

// 省略了导入的包
public class SnmpTest1 {
    public static void main(String[] args) {
    try {
            Snmp snmp = new Snmp(new DefaultUdpTransportMapping());
            snmp.listen();
            
            CommunityTarget target = new CommunityTarget();
            target.setAddress(GenericAddress.parse("udp:192.168.100.61/161"));
            target.setCommunity(new OctetString("public"));
            target.setTimeout(1000);
            target.setRetries(2);
            target.setVersion(SnmpConstants.version1);
            
            PDU pdu = new PDU();
            pdu.add(new VariableBinding(new OID("1.3.6.1.2.1.1.2.0")));
            pdu.add(new VariableBinding(new OID("1.3.6.1.2.1.1.3.1")));
            pdu.add(new VariableBinding(new OID("1.3.6.1.2.1.1.3.2")));
            pdu.add(new VariableBinding(new OID("1.3.6.1.2.1.1.3.3")));
            pdu.add(new VariableBinding(new OID("1.3.6.1.2.1.1.3.4")));
            pdu.add(new VariableBinding(new OID("1.3.6.1.2.1.1.4.0")));
            
            PDU newpdu = getSucPDU(snmp,target,pdu);
            ResponseEvent event = snmp.get(newpdu, target);
            PDU resp = event.getResponse();
            for (int i = 0; i < resp.size(); i++) {
                VariableBinding vb = resp.get(i);
                System.out.println(vb.getOid().toString() +"^^^^"+ vb.getVariable());
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        
    }

    private static PDU getSucPDU(Snmp snmp, CommunityTarget target, PDU pdu) throws IOException {
        ResponseEvent event = snmp.get(pdu, target);
        PDU resp = event.getResponse();
        int errorIndex = resp.getErrorIndex();
        if(errorIndex != 0){
            VariableBinding vb = resp.get(errorIndex -1);
            OID errorOid = vb.getOid();
            System.out.println(errorOid + ":" + resp.getErrorStatusText());
            pdu.remove(errorIndex-1);
            getSucPDU(snmp,target,pdu);
            return pdu;
        }
        return null;
    }
}

2. 运行结果为：
