[c-nsp] speed and duplex change of remote router

[Mike Hale]

Not without taking the link down.

If you don't mind taking the link down for a little bit, you can run a
script locally that telnets into the router, changes the speed/duplex,
then tries to ping out.  If it can't for more than a minute, telnet
back into the box and change the speed/duples back.

Another way is to use a scheduled reload (e.g. reload in 5) and then
cancel the reload if the change worked.

I know if you change the speed and its wrong you will lose connectivity.  I have a link that is setup auto, but my isp has their end setup 10 full.  I would prefer not to drive all the way to this place to change the speed to 10 full on the wan interface.
