介绍
这个工具像Windows命令行工具arp.exe一样显示和修改IP/物理地址转表(ARP表).
该工具将做两件事情：
1）显示ARP表
2）添加、删除、修改ARP表
这两项工作通过SNMP(简单网络管理协议)扩展库来完成。
通过SNMP处理IP和MAC地址
你可以通过SNMP读取或修改ARP表，通过SNMP得到或设置对象信息。SNMP命令的请求与响应是依靠MIB（管理信息库）来完成的。
MIB为树装结构，MIB拥有所有为我们所用的可管理对象，更多的信息可以参考RFC1213(http://www.ietf.org/rfc/rfc1213.txt),
也可以查看文件：%SystemRoot%\system32\*.mib,您可以用notepad.exe打开并查看%SystemRoot%\system32\mib_ii.mib中的所有条目。
下面是MIB ipNetToMediaEntry条目
ipNetToMediaEntry OBJECT-TYPE
SYNTAX IpNetToMediaEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"Each entry contains one IpAddress to ~physical~
address equivalence."
INDEX { ipNetToMediaIfIndex,
ipNetToMediaNetAddress }
::= { ipNetToMediaTable 1 }
MIB通过OID(对象标识)数字来存取对象，每个对象拥有一个数字，子对象拥有父对象的数字和自己的数字，
数字之间用"."来分割。例如：父对象数字为"1",子对象数字为"3",则子对象OID为"1.3",子对象的子对象可以
是"1.3.6",..."1.3.6.1.2.1"等等...
下面是对象树的简单框图：
类的初始化
我们使用SnmpExtensionQuery函数来发送SNMP请求，使用之前我们必须调用SnmpExtensionInit来初始化SNMP扩展代理DLL。
这两个函数包含于Microsoft的inetmib1.dll中.
因此我们在类的构造函数中加载动态库并得到函数的地址，然后调用SnmpExtensionInit初始化SNMP扩展代理DLL。
下面是CARP类的构造函数
//////////////////////////////////////////////////////////////////////
// Construction/Destruction
//////////////////////////////////////////////////////////////////////
CARP::CARP()
{
// Load dynamic library: inetmib1.dll
hMIBLibrary = LoadLibrary(TEXT("inetmib1.dll"));
// If library loaded, get addresses of (SnmpExtensionInit, pfnSnmpExtensionQuery) functions
if (hMIBLibrary)
{
pfnSnmpExtensionInit = (PFNSNMPEXTENSIONINIT) GetProcAddress(hMIBLibrary, "SnmpExtensionInit");
pfnSnmpExtensionQuery = (PFNSNMPEXTENSIONQUERY) GetProcAddress(hMIBLibrary, "SnmpExtensionQuery");
// If success get addresses and initialize SNMP, bInitialized = true
if (pfnSnmpExtensionInit && pfnSnmpExtensionQuery)
{
HANDLE hPollForTrapEvent;
AsnObjectIdentifier aoiSupportedView;
bInitialized = pfnSnmpExtensionInit(0, &hPollForTrapEvent, &aoiSupportedView);
}
}
else
{
// If fail to get addresses, bInitialized = false
bInitialized = FALSE;
AfxMessageBox(_T("Load library fail"));
}
}
得到ARP条目
函数GetEntries类似arp.exe -a,可以得到ARP条目，函数有三个参数：
PTable指针指向arpTable结构数组，用于填充IP和MAC地址。
TableLength是数组长度
AdapterIndex是NIC适配器的编号。
我使用3个OID来得到ARP表条目：
OID[0] = "1.3.6.1.2.1.4.22.1.1" ，得到接口索引号。
然后和OID[1] = "1.3.6.1.2.1.4.22.1.2"比较，得到IP和MAC地址
OID[2] = "1.3.6.1.2.1.4.22.1.4", 得到条目类型(静态或动态)

// Function: GetEntries: Read ARP table for specific NIC interface.
//

int CARP::GetEntries(arpTable* pTable, int TableLength, int AdapterIndex)
{
// Be sure initialize SNMP true
if (!bInitialized)
return 0;

编辑ARP表条目
EditEntry函数可以添加、修改、删除ARP条目。
添加动态条目，就像：arp.exe 1.2.3.4 11-22-33-44-55-66
添加静态条目，就像：arp.exe –s 1.2.3.4 11-22-33-44-55-66
删除条目，就像：arp.exe –d 1.2.3.4
添加新条目，如果IP地址在ARP表中不存在则添加进去，如果已经存在则被更新。
删除条目，只需要提供NIC接口中的IP地址，MAC地址不需要提供。
函数有四个参数：4字节的IPAddress，6字节的MACAddress，条目类型（2：删除，
3：动态，4：静态）
AdapterIndex:NIC适配器编号
我使用4个OID设置ARP表条目：
OID[0] = "1.3.6.1.2.1.4.22.1.1", 设置接口编号
OID[1] = "1.3.6.1.2.1.4.22.1.2", 设置MAC地址
OID[3] = "1.3.6.1.2.1.4.22.1.3", 设置IP地址
OID[2] = "1.3.6.1.2.1.4.22.1.4", 设置条目类型 (静态或动态), 或删除
//-----------------------------------------------------------------------
// Function: EditEntry: Add/Modify/Remove ARP entry for specific NIC interface.
//
// Parameters:
// IPAddress Array of 4 BYTES, 4 octs of IP Address
// MACAddress Array of 4 BYTES, 6 octs of MAC Address
// Type Entry type (2:Remove, 3:Dynamic, 4:Static)
