Introduction
This document describes the Cisco IOS Software that runs as a process within Cisco IOS XE in what is called the IOS daemon, or IOSd. While many of the infrastructure components have migrated from Cisco IOS to Cisco IOS XE such as High Availability, the features of Cisco IOS Software are exactly the same as those that run within the Cisco IOS XE as they do in a traditional Cisco IOS release.
This document is important to understand the mapping between Cisco IOS XE software versions and respective classic IOS version that run on Cisco Catalyst 3850 switches.
It also explains the suffix at the end of Catalyst 3850/3650 product ID and what it means.

Relation between Product ID and License Feature Set
When you navigate to the Cisco Software Download page for Catalyst 3850/3650 switches, you will find the full Product ID. However, it will not exactly match with your Product ID under the show version output. It will be without the last letter that is
Cisco page: Catalyst 3850-24P-S Switch
Show version: WS-C3850-24P
Final letter makes reference to a feature set that switch ships with, the show version or show license right-to-use output will show the current license.
Table 2 shows the possible letters and which feature sets they translate to.
