Release Notes for Cisco Embedded Wireless Controller on Catalyst Access Points, Cisco IOS XE 17.15.x
Introduction to Cisco Embedded Wireless Controller on Catalyst Access Points
The Cisco Embedded Wireless Controller on Catalyst Access Points is a version of the Cisco IOS XE-based controller software on Catalyst access points (AP). In this solution, a Catalyst AP that is running the Cisco Embedded Wireless Controller on Catalyst Access Points software, is designated as the primary AP. Other APs, referred to as subordinate APs, associate to this primary AP.
The Cisco Embedded Wireless Controller on Catalyst Access Points provides enterprise-level WLAN features while maintaining operational simplicity and affordability. This solution is targeted at small and medium-sized business (SMB) customers or distributed enterprises, and can be run at single site deployments.
-
The controllers come with high availability (HA) and seamless software updates. This keeps your services on always, both during planned and unplanned events.
-
The deployment can be managed using a mobile application, Cisco Catalyst Center, Netconf/Restconf, web-based GUI, or CLI.

Upgrading the Controller Software
This section covers the various aspects of upgrading the controller software.
![]() Note |
Before converting from CAPWAP to embedded wireless controller (EWC), ensure that you upgrade the corresponding AP with the CAPWAP image in Cisco AireOS Release 8.10.105.0. If this upgrade is not performed, the conversion will fail. |
Finding the Software Version
The following table lists the Cisco IOS XE 17.15.x software for Cisco Embedded Wireless Controller on Catalyst Access Points.
Choose the appropriate AP software based on the following:
-
Cisco Embedded Wireless Controller on Catalyst Access Points software to be used for converting the AP from an unified wireless network CAPWAP lightweight AP to a Cisco Embedded Wireless Controller on Catalyst Access Points-capable AP (primary AP)
-
AP software image bundle to be used either for upgrading the Cisco Embedded Wireless Controller on Catalyst Access Points software on the primary AP or for updating the software on the subordinate APs or both
Prior to ordering Cisco APs, see the corresponding ordering guide for your Catalyst or Aironet access point.

Supported Access Point Channels and Maximum Power Settings
Supported access point channels and maximum power settings on Cisco APs are compliant with the regulatory specifications of channels, maximum power levels, and antenna gains of every country in which the access points are sold. For more information about the supported access point transmission values in Cisco IOS XE software releases, see the Detailed Channels and Maximum Power Settings document at https://www.cisco.com/c/en/us/support/ios-nx-os-software/ios-xe-17/products-technical-reference-list.html.
For information about Cisco Wireless software releases that support specific Cisco AP modules, see the "Software Release Support for Specific Access Point Modules" section in the Cisco Wireless Solutions Software Compatibility Matrix document.
Guidelines and Restrictions
Internet Group Management Protocol (IGMP)v3 is not supported on Cisco Aironet Wave 2 APs.
Embedded Wireless Controller SNMP configuration is supported in Cisco Catalyst Center.
High memory usage on AP running Embedded Wireless Controller. Enabling crash kernel on the AP consumes additional memory on the AP. Hence, if crash kernel is enabled, the overall memory usage of the device will increase and will impact the scale numbers. On Cisco Catalyst 9130 Access Points, the memory consumption is a high of 128 MB.
During the EWC HA pair selection, after a power outage, the standby AP fails to come up in the new EWC HA pair. Another EWC capable AP becomes the standby AP and fails to come up as well. To avoid this situation, ensure that the same IP address is enforced on the active or standby APs during HA pair selection.
Interoperability with Clients
