How to decrypt Cisco firmware?

Question

Cisco

People and nonhumans. Rshiel is getting ready for certification. I found the firmware, but it’s not clear, however, in this diabolical letter. Can someone decipher what and how?

Answer 1

The general principle of naming is well explained here:

Judging by the screenshot, you are interested in how to determine the so-called FeatureSet by name - the easiest way to do this is in their own Web utility :
tools.cisco.com/ITDIT/CFN/jsp/SearchBySoftware.jsp
ipbase - the most basic functionality of
adventerprise - one of the broadest FeatureSet
spservices - specific functionality for
k9 providers - strong encryption
, etc. - See link above for details.
