Release Notes for Cisco Embedded Wireless Controller on Catalyst Access Points, Cisco IOS XE 17.3.x1
What's New in Cisco IOS XE Amsterdam 17.3.2aTable 1: Software Features Introduced on Cisco Embedded Wireless Controller on Catalyst Access Points
Description and Documentation LinkFeature Name
An enhanced version of Smart Licensing, with theoverarching objective of providing a licensing solutionthat does not interrupt the operations of your network,rather, one that enables a compliance relationship toaccount for the hardware and software licenses youpurchase and use.
With this licensing model, you do not have tocomplete any licensing-specific operations, such asregistering or generating keys before you start usingthe software and the licenses that are tied to it. Onlyexport-controlled and enforced licenses require Ciscoauthorization before use. License usage is recordedon your device with timestamps and the requiredworkflows can be completed at a later date.
Multiple options are available for license usagereporting – this depends on the topology youimplement. You can use the Cisco Smart LicensingUtility (CSLU)Windows application, or report usageinformation directly to CSSM. A provision for offlinereporting for air-gapped networks, where youdownload usage information and upload to CSSM, isalso available.
Starting with this release, Smart Licensing UsingPolicy is automatically enabled on the device. This isalso the case when you upgrade to this release. Bydefault, your Smart Account and Virtual Account inCSSM is enabled for Smart Licensing Using Policy.
For more information, see the Smart Licensing UsingPolicy chapter.

What's New in Cisco IOS XE Amsterdam 17.3.1Table 2: Software Features Introduced on Cisco Embedded Wireless Controller on Catalyst Access Points
Description and Documentation LinkFeature Name
The Public Key Infrastructure (PKI) Managementpage now displays the following tabs:
Trustpoints tab: Used to add, create or enroll a newtrustpoint. This also displays the current Trustpointsconfigured on the controller and other details of thetrustpoint. You can also see if the trustpoint is in usefor any of the features.
CA Server tab: Used to enable or disable theCertificate Authority (CA) server functionality on thecontroller. The CA server functionality should beenabled for the controller to generate a Self-SignedCertificate (SSC).
Key Pair Generation tab: Used to generate key pairs.
Certificate Management tab: Used to generate andmanage certificates, and perform all certificate relatedoperations, on the controller.
Enhanced Certificate Management Through GUI
During AP image download, the Embedded WirelessController calculates the current percentage of thedownload and the estimated time of the completionof the download.
The Software Update Status section in the GUIdisplays the update status bar that shows the progressof the software update, such as, Initiate, ControllerImage Download, AP Image Download, NetworkUpgrade, Activate, and Reload.
The following commands were introduced:
• show wireless ewc-ap ap image predownloadstatus

Important Notes
Licensing Information Missing In Case of Simultaneous Dual Failure of the Active and Standby EmbeddedWireless Controller - AP Controller
In a network of Cisco Embedded Wireless Controller on Catalyst Access Points (EWC) - AP, one of the APswill be elected as the controller (you can configure the same by giving priority to one of the APs). If the activeand standby EWCs fail simultaneously, a couple of other APs become the new active and standby EWCs. Insuch a case, the licensing information stored in the original active and standby EWCs will not be available inthe new active-standby pair controllers.
To resolve this issue manually, do the following:
1. Recover the previously active or standby controller.
2. Wait for it to become the standby controller, and perform a failover to make it an active controller.

3. If this method fails, or if it is not possible due to the original failure, then install the trust code on thenewly active controller.
Supported Cisco Access Point PlatformsThe following Cisco access points are supported in the Cisco Embedded Wireless Controller on CatalystAccess Points network. Note that the APs listed as primary APs can also function as subordinate APs.

Upgrading the Controller SoftwareThis section covers the various aspects of upgrading the controller software.
For information on upgrading the controller software, see the "Software Management" section in the CiscoEmbedded Wireless Controller on Catalyst Access Points Online Help.
Before converting from CAPWAP to embedded wireless controller (EWC), ensure that you upgrade thecorresponding AP with the CAPWAP image in Cisco AireOS Release 8.10.105.0. If this upgrade is notperformed, the conversion will fail.
Note
Finding the Software VersionThe following table lists the Cisco IOS XE 17.3.x software for Cisco Embedded Wireless Controller onCatalyst 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 theAP from an unified wireless network CAPWAP lightweight AP to a Cisco EmbeddedWireless Controlleron Catalyst Access Points-capable AP (primary AP)
• AP software image bundle to be used either for upgrading the Cisco Embedded Wireless Controller onCatalyst Access Points software on the primary AP or for updating the software on the subordinate APsor both
Prior to ordering Cisco APs, see the corresponding ordering guide for your Catalyst or Aironet access point.
Guidelines and RestrictionsInternet Group Management Protocol (IGMP)v3 is not supported on Cisco Aironet Wave 2 APs.
Embedded Wireless Controller SNMP configuration is supported in DNAC.
Highmemory usage onAP running EmbeddedWireless Controller. Enabling crash kernel on the AP consumesadditional memory on the AP. Hence, if crash kernel is enabled, the overall memory usage of the device willincrease and will impact the scale numbers. On Cisco Catalyst 9130 Series Access Points, the memoryconsumption is a high of 128 MB.
While upgrading EWC, if you have enabled crash kernel on the AP, disable the feature and then enable itagain post upgrade. Ensure that you reboot the AP post enable or disable.
