Thanks for the output.

The appliance is a 3945, however, the IOS found in the directory output shows the file meant for a 3945e.

IOS for the 3945 can be found HERE.

Thank you for your help but im sorry for my stupidity can you please explain what the importance about the e is please???????

[Leo Laohoo]

"e" is the later model. 3945 is the first "series" that came out and about 18 months later the 3925e/3945e came out with bigger "grunt". Because of this, there are two different IOS files, one for the plain one and the other for the "e".
