I have a brand new Cisco 2801. It is currently loaded with C2801-ADVSECURITYK9-M, Version 12.4<15>T4. The IOS image is c2801-advsecurityk9-mz.124-15.T4.bin.
I want to go ahead and update it to the latest IOS but I was curious what all the different types of IOS images would have on my router.
Will i screw up the router if I try to flash it with c2801-adventerprisek9-mz.124-23.bin? Or should i just stick with c2801-advsecurityk9-mz.124-23.bin?
Any help is appreciated. Here is the downloads page I was getting my IOS images.
