CISCO 1760 ROUTER

We need to update the ADSL  Broadband username & password on a UK installed Cisco 1760 router to reflect the new ISP - Gotadsl/Nildram account.

Both the current, and the new account use standard UK settings VC, 0, 38 etc so this information will not be changed.

We have command line console access - is there a simple menu command that will enable us to do this - and to confirm via the show command that the update has been made correctly?

Also - what is the console menu command to confirm the internal IP of the Router?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
