基于vlan连接到服务器的批处理文件

Question

这是我的自动化脚本的一个片段，用于基于vlan从特定服务器进行映像。该脚本检查其IP以及它所在的vlan，然后使用它连接到特定服务器。我的问题是我得到一个"如果此时意外"错误。请帮忙。

:getvlan
for /f "tokens=2 delims=:" %%a in ('ipconfig ^| find "IPv4 Address"') do set IP=%%a
for /f "tokens=3 delims=." %%j in ('echo %IP%') do set vlan=%%j

if %vlan% GEQ 100 (if %vlan% LEQ 119 (
   set servernowack=server1
   set seshtype=M
) if %vlan% GEQ 130 (if %vlan% LEQ 139 (
   set servernowack=server2
   set seshtype=D
) if %vlan% GEQ 140 (if %vlan% LEQ 149 (
   set servernowack=server3
   set seshtype=D
) if %vlan% GEQ 150 (if %vlan% LEQ 159 (
   set servernowack=server4
   set seshtype=M
) if %vlan% GEQ 160 (if %vlan% LEQ 169 (
   set servernowack=server5
   set seshtype=D
) else (
   goto fail
)
goto getserverip

开放比封闭括号多得多。因此 cmd.exe 无法确定每个块 if 在你的批处理代码中，一个简单的语法错误很容易解决。

@echo off
:getvlan
for /f "tokens=2 delims=:" %%a in ('%windir%\system32\ipconfig.exe ^| %windir%\system32\find.exe "IPv4 Address"') do set IP=%%a
for /f "tokens=3 delims=." %%j in ('echo %IP%') do set vlan=%%j

if %vlan% GEQ 100 (
   if %vlan% LEQ 119 (
      set servernowack=server1
      set seshtype=M
      goto getserverip
   )
)
if %vlan% GEQ 130 (
   if %vlan% LEQ 139 (
      set servernowack=server2
      set seshtype=D
      goto getserverip
   )
)
if %vlan% GEQ 140 (
   if %vlan% LEQ 149 (
      set servernowack=server3
      set seshtype=D
      goto getserverip
   )
)
if %vlan% GEQ 150 (
   if %vlan% LEQ 159 (
      set servernowack=server4
      set seshtype=M
      goto getserverip
   )
)
if %vlan% GEQ 160 (
   if %vlan% LEQ 169 (
      set servernowack=server5
      set seshtype=D
      goto getserverip
   )
)
echo Error: Failed to determine vlan!
goto :EOF

:getserverip
