Re: CME upgrade issue

I ran into this once before..

I ended up having to do a write erase (twice), reloading and reconfiguring from scratch.


Re: CME upgrade issue

That means you earsed the startup completely... got the router to factory settings and the installed the latest IOS as fresh or did u upgrade form the previous one. ... hope there is some other solution to this... does any one know what it would be?

Re: CME upgrade issue

I installed the latest IOS fresh .. and yes, it will erase the startup..

Make sure you copy your config to tftp or at least to a notepad file..
