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.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

This document is not restricted to specific software and hardware versions.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

IOS XE to IOS Version Mapping

The Table 1 ilustrates the IOS XE to IOS mapping for Catalyst 3850/3650 platforms.

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.
