I am trying to upgrade the license for 3750X-48P-S switch to latest 15.X release (15.2.1E1). but end up with the IOS uncompatable error. Presently the IOS image and version on the switch is C3750E-UNIVERSALK9NPE-M & 12.2(55)SE5
I downloaded multiple images from Cisco.com under switches section 3750X-48P-S (http://software.cisco.com/download/release.html?mdfid=282979366&flowid=2632&softwareid=280805680&release=15.2.1E1&relind=AVAILABLE&rellifecycle=ED&reltype=latest)
I use the command archive download-sw /safe tftp://x.x.x.x/iosname.tar flash: and it sucessfully uploaded the image but gave error while extracting and for other IOS at the time i enter the command and press enter it gave ios does not match error.
This switch has Permenent IPBase license and IPServices evaluation license. I have attached show version and show license all output. First time i am upgrading the IOS which has name npe in the name (C3750E-UNIVERSALK9NPE-M).
Kindly advise what will be the right IOS to upgrade the present 12.2(55)SE5 to the latest 15.x version.
Input in this regard will be highly appriciated.
Thanks in Advance.
