SNMP ipAddrTable Windows、AIX和Linux的不同

Windows和 AIX返回5个项目：

 ipAdEntAddr    1.3.6.1.2.1.4.20.1.1
 ipAdEntIfIndex    1.3.6.1.2.1.4.20.1.2
 ipAdEntNetMask    1.3.6.1.2.1.4.20.1.3
 ipAdEntBcastAddr    1.3.6.1.2.1.4.20.1.4
 ipAdEntReasmMaxSize    1.3.6.1.2.1.4.20.1.5
--------------------- 
完整的实现了标准

LINUX返回4个项目：

php区别对待代码：

if($this->operating_system == 'windows')
        {
            $ipAd = array_chunk($result,count($result)/5);
        }
        if($this->operating_system == 'linux')
        {
            $ipAd = array_chunk($result,count($result)/4);
        }
        if($this->operating_system == 'aix')
        {
            $ipAd = array_chunk($result,count($result)/5);
        }        //print_r($if);
