You
can use the Netsh.exe tool to perform the following tasks:
- Configure interfaces.
- Configure routing protocols.
- Configure filters.
- Configure routes.
- Configure remote access behavior for Windows-based remote access routers that are running the Routing and Remote Access Server (RRAS) Service.
- Display the configuration of a currently running router on any computer.
- Use the scripting feature to run a collection of commands in batch mode against a specified router.
The
syntax for the Netsh.exe tool is:
netsh
[-r router name] [-a AliasFile] [-c Context] [Command | -f ScriptFile]
To
display a list of subcontexts and commands that can be used in a context, type
the context name followed by a space and a ? at the netsh> command prompt.
For example, to display a list of subcontext and commands that can be used in
the /routing context, type routing ? at the netsh> command prompt, and then
press ENTER.
Contexts
Context
strings are appended to the Netsh.exe tool command and are passed to an associated
helper. The helper may have one or more entry points that map to contexts. Some
of the contexts available in the Netsh.exe tool are:
Context Command: /dhcp
Result: Changes to the Dynamic Host Configuration Protocol (DHCP) context.
Context Command: /ras
Result: Changes to the Remote Access Server (RAS) context.
Context Command: /routing
Result: Changes to the routing context.
Context Command: /wins
Result: Changes to the Windows Internet Name Service (WINS) context.
Contexts may also nest within other contexts. For example, the following contexts operate within the netsh>ras context:
Context Command: /ip
Result: Changes to the Internet Protocol (IP) context.
Context Command: /ipx
Result: Changes to the Internetwork Packet Exchange (IPX) context.
Context Command: /netbeui
Result: Changes to the NetBios Enhanced User Interface (NETBEUI) context.
The following subcontexts operate within the netsh>routing ip context:
Context Command: /autodhcp
Result: Changes to the autodhcp subcontext.
Context Command: /dnsproxy
Result: Changes to the dnsproxy subcontext.
Context Command: /igmp
Result: Changes to the Internet Group Membership Protocol (IGMP) subcontext.
Context Command: /mib
Result: Changes to the Management Information Base (MIB) subcontext.
Context Command: /nat
Result: Changes to the Network Address Translation (NAT) subcontext.
Context Command: /ospf
Result: Changes to the Open Shortest Path First (OSPF) subcontext.
Context Command: /relay
Result: Changes to the relay subcontext.
Context Command: /rip
Result: Changes to the Routing Information Protocol (RIP) subcontext.
Context Command: /dhcp
Result: Changes to the Dynamic Host Configuration Protocol (DHCP) context.
Context Command: /ras
Result: Changes to the Remote Access Server (RAS) context.
Context Command: /routing
Result: Changes to the routing context.
Context Command: /wins
Result: Changes to the Windows Internet Name Service (WINS) context.
Contexts may also nest within other contexts. For example, the following contexts operate within the netsh>ras context:
Context Command: /ip
Result: Changes to the Internet Protocol (IP) context.
Context Command: /ipx
Result: Changes to the Internetwork Packet Exchange (IPX) context.
Context Command: /netbeui
Result: Changes to the NetBios Enhanced User Interface (NETBEUI) context.
The following subcontexts operate within the netsh>routing ip context:
Context Command: /autodhcp
Result: Changes to the autodhcp subcontext.
Context Command: /dnsproxy
Result: Changes to the dnsproxy subcontext.
Context Command: /igmp
Result: Changes to the Internet Group Membership Protocol (IGMP) subcontext.
Context Command: /mib

Netsh.exe Commands
The
following additional commands can be used with the Netsh.exe tool:
NOTE: Optional parameters are shown in brackets ([ ]). Alternative entries are shown with a pipe (|) character between them.
Context Command: /?
Result: Displays help.
Context Command: /abort
Result: Discards any changes made in offline mode. No effect in online mode.

Result: Installs the helper .dll file in netsh.exe.
Context Command: /alias [alias-name] [string1] [string2 ...]
Result: If /alias, lists all aliases. If /alias alias-name, displays the equivalent string. If /alias alias-name string1 string2 ..., sets alias-name to the specified strings.
Context Command: /bye
