SOS - How to find out MTU on Windows

Hi,

Could some one please tell me how to find out MTU on Windows 2003?
'ipconfig /all' doesn't show that information.

Also, how to find out "path MTU", from one host to the other?

Thanks a lot!

There's not a lot of point cross-posting this to an OS/2 newsgroup, is
there? OS/2 is a completely different, and arguably superior, system
that has the great advantage of not coming from Microsoft. Most of us
don't use Windows at all.

 

Why not use the help file provided by 2003 windows.

Since I found this thread first during my quest to find a way to display (as opposed to derive) an IP interface's MTU, I figured I'd feed back the answer I found elsewhere.

First, make sure the service called "Routing and Remote Access" (aka. "RemoteAccess") is started. It doesn't have to be started automatically; just running before you type the next command.

In Windows XP, type the following command at the DOS/Command prompt:

C:\>netsh interface ip show interface

The output will show you all kinds of cool things, including:

For Vista, I've been told that the command is now 'netsh interface ipv4 show subinterface', but I have no proof of that.
