脚本模版：
tclsh
foreach TEST {
116.228.7.174
192.168.1.1
} { ping 202.96.209.5 repeat 10 so $TEST }
Cisco IOS 提供强大的脚本和宏命令来帮助工程师来测试网络。提供一个高效，准确，简单的测试全网连通性的问题。
Cisco IOS 上路由器和交换机使用的命令不一样。先从路由器开始：
Router，使用的是脚本来测试。只用我们把这些脚本在一个记事本编辑好，然后贴到CLI 中就可以让设备自动完成了。路由器不能存放脚本。我们拿以下的例子来说，下面是脚本文件：
tclsh
foreach TEST {
192.168.255.1
192.168.255.2
192.168.255.3
192.168.255.4
192.168.255.5
192.168.255.6
192.168.255.7
192.168.255.8
192.168.255.9
192.168.255.10
} { ping $TEST repeat 5 }
上述中，TEST 是一个变量，你可以随便起。我们设定了ping 的次数为5 次。
然后在路由器的全局模式下按照以下操作：
Router>enable
Router#tclsh
Router(tcl)#
然后把上述的脚步复制到CLI 中。路由器会自动执行。
Rack17R1#tclsh
+>foreach TEST {
+>192.168.255.1
+>192.168.255.2
+>192.168.255.3
+>192.168.255.4
+>192.168.255.5
+>192.168.255.6
+>192.168.255.7
+>192.168.255.8
+>192.168.255.9
+>192.168.255.10
+>} { ping $TEST repeat 5 }

我们看到了全网都可达，如果不通，一定要找到时什么原因。如果不知道原因，就需要查找原因。这样你就可以用一个命令来测试全网的可达性。
==========================================================================================
交换机就使用使用宏命令来测试。宏命令是可以保存在交换机上的。
宏命令如下：（全局模式下使用）
macro name TEST
do ping 192.168.255.1
do ping 192.168.255.2
do ping 192.168.255.3
do ping 192.168.255.4
do ping 192.168.255.5
do ping 192.168.255.6
do ping 192.168.255.7
do ping 192.168.255.8
do ping 192.168.255.9
do ping 192.168.255.10
@
把上面的宏命令复制到CLI 中后。我们就可以调用它了。
Switch(config)#macro global apply TEST 就可以让交换机自己调用刚才创建的宏来测试。
=============================
Rack17SW1(config)#macro global apply TEST

这样在交换机上就可以测试全网可达性了。
那么我们怎么去复制网络中的地址呢？我有两种方式：
1. sh ip int bri
Rack17R1#sh ip int bri
Interface IP‐Address OK? Method Status Protocol
FastEthernet0/0 192.168.255.1 YES NVRAM up up
FastEthernet0/1 192.168.255.2 YES NVRAM up up
我们看到这种方式比较笨重。
2. sh ip alias
Rack17R1#sh ip alias
Address Type IP Address Port
Interface 192.168.255.1
Interface 192.168.255.2
Interface 192.168.255.3
我们看到第二种方式比较简单。我们可以直接使用记事本的替换功能将前面的单词替换掉。就可以直接使用了。
