Release Notes for Cisco Embedded Wireless Controller on Catalyst Access Points, Cisco IOS XE Bengaluru 17.6.x
Introduction to Cisco Embedded Wireless Controller on Catalyst Access Points
 Caution |
Problem Description: Authentication fails when attempting to upgrade software using the "CCO mode" in Cisco Embedded Wireless Controller (EWC) on a Cisco Catalyst Access Point (EWC-AP). This issue occurs when attempting to upgrade from a software release prior to one of the following releases: 17.3.x, 17.6.x, 17.9.5, 17.12.3, and 17.14.1. Background: From May 1, 2024, onwards, Cisco Connection Online (CCO, known as cisco.com) will use a new authentication system for EWC-AP. This system is not backward compatible with the earlier EWC-AP software releases. EWC-AP software developed after January 31, 2024, will be able to authenticate with Cisco.com, before and after May 1, 2024. The releases include: 17.9.5 and later, 17.12.3 and later, and 17.14.1 and later. Workaround: Download the desired EWC-AP image and load it into the EWC-AP over TFTP, SFTP, or (Desktop) HTTP. Upgrade to one of the following releases:
After the upgrade, the CCO method for upgrades will work. For more information, see Field Notice: FN74124. |
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.

Automated Software Download Version 4 (ASDv4) Migration |
Cisco Embedded Wireless Controller on Catalyst Access Points requires Automated Software Download Version 3 (ASDv3) to download software from Cisco.com. However, ASDv3 is being replaced by ASDv4 from July 2022. Consequently, the software download feature will not work on older Cisco IOS XE releases. We recommend that you upgrade your device software image to Cisco IOS XE Amsterdam 17.3.5a, Cisco IOS XE Bengaluru 17.6.3, Cisco IOS XE Cupertino 17.8.1 (when available), or a later release to enable the software download feature with ASDv4. |
This release also includes critical bug fixes relating to scale and stability improvements.

Cisco Catalyst 9124AXE Outdoor Access Points is supported in EWC, from Cisco IOS XE Bengaluru 17.6.2 onwards. |
| Mesh and Mesh + Flex Support for Cisco Catalyst 9124AXE Outdoor Access Points |
Mesh feature and Mesh + Flex feature is supported in Cisco Catalyst 9124AXE outdoor Access Points. For more information, see the chapter Mesh Access Points. |
| Mesh and Mesh + Flex Support for Cisco Catalyst 9124AXI/D Outdoor Access Points |
Mesh feature and Mesh + Flex feature is supported in Cisco Catalyst 9124AXI/D outdoor Access Points. For more information, see the chapter Mesh Access Points. |
 Note |
The following is recommended for EWC deployments: In a normal EWC (EWC on AP) network, the controller image is transferred to all EWC capable APs. However, in a mesh topology, it adds additional traffic flow on the wireless backhaul when there are EWC capable MAPs. This could make the image download procedure slow and error prone. To alleviate the issue, an option has been added, where the controller image is not copied to the EWC capable MAPs, when they are in CAPWAP mode. Changing the EWC capable MAPs to CAPWAP APs, does not impact the EWC network redundancy design, as MAPs do not spawn the controller. |
What's New in Cisco Embedded Wireless Controller on Catalyst Access Points, Cisco IOS XE Bengaluru 17.6.1b

Note |
What's New in Cisco Embedded Wireless Controller on Catalyst Access Points, Cisco IOS XE Bengaluru 17.6.1

Description and Documentation Link |
|---|---|
|
Access Point Tag Persistency |
In Cisco IOS XE Bengaluru 17.6.1, AP tag persistency is enabled globally on the controller. When APs join a controller with the tag persistency enabled, the mapped tags are saved on the AP without having to write the tag configurations on each AP, individually. The following command is introduced:
For more information, see the chapter Access Point Tag Persistency. |
|
AP Group NTP Server |
The global NTP server configuration is replaced with per-AP group NTP server configuration. Now, you cannot configure the Cisco Hyperlocation feature without the per-AP group NTP server. The following commands are introduced:
For more information, see the chapter AP Group NTP Server. |
|
IPv6 Ready Certification |
The IPv6 feature is enhanced with the implementation of various IPv6 functionalities that are required to comply with the latest RFC specifications. For more information, see the chapter IPv6 Ready Certification. |
|
MAC Address Consistency |
The format of the MAC addresses of some of the fields in the following CLIs are updated from xx:xx:xx:xx:xx to xxxx.xxxx.xxxx.
|
|
Regulatory Compliance (Rest of World) for Domain Reduction |
This feature enhancement helps to reduce the number of regulatory domains by modifying the existing preprovision domain workflow to determine regulatory domain at runtime per country code. A new ROW domain is introduced and merged to include nine domains. Every AP can determine its own regulatory domain from one of the 9 domains with regulated power table and allowed radio channels. Until Cisco IOS XE Bengaluru 17.5.x, AP used the global controller country list to configure and validate all the country codes. For more information, see the chapter Regulatory Complaince Rest of the World for Domain Reduction. |
|
Mesh Support for Cisco Catalyst 9124AXI/D Outdoor Access Points |
From Cisco IOS XE Bengaluru 17.6.1 onwards, the mesh feature is supported in Cisco Catalyst 9124AXI/D outdoor Access Points with EFT quality. For queries on this feature, reach out to the mailer: wireless-9124-ithaca-mesh-eft-support For more information, see the chapter Mesh Access Points. |
|
Mesh support on Cisco Catalyst Wireless Mobile Application |
With the introduction of the mesh feature in the EWC platform for Cisco Catalyst 9124AXI/D outdoor Access Points with EFT quality, the mobile application supports the following mesh use cases:
For more information, see the EWC Mob App User Guide. |
|
Support for WiFi6 Pluggable Module in EWC |

Upgrading the Controller Software
This section covers the various aspects of upgrading the controller software.
For information on ASDv4 migration, see the What's New in Cisco IOS XE Bengaluru 17.6.3 section.
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 17.6.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.

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.
