cisco IOS software

Fly1Time · April 2005

I have a 2511 router with a IOS of 4.xx and a 2511 (newer router) with a version of 11.x on it. Can anyone tell me if it is possible to copy IOS ver. from one router to another, if so, then how?

sorry did you say ios version 4??? how old is this router?? Ive only seen version 10.x a couple of times and that was a few years back. I dont even know how old version 4 is! are you sure that is you IOS version and not your system bootstrap?

what happens when you issue a show version just in case id doesnt recognise it try write memory

you should get

you can backup the config of you 11.x router by running a tftp server and issue the command copy flash tftp

then you can load it in to the other router by using copy tftp flash, if this command isnt recognised try config memory
