Release Notes for Cisco Embedded Wireless Controller on Catalyst Access Points, Cisco IOS XE Cupertino 17.7.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. In this solution, a Catalyst access point (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 Digital Network Architecture (DNA) Center, Netconf/Restconf, web-based GUI, or CLI.

What's New in Cisco Embedded Wireless Controller on Catalyst Access Points, Cisco IOS XE Cupertino 17.7.1

Table 1. New and Modified Software Features

Feature Name

Description and Documentation Link

Guest Anchor with Centralized EoGRE

The Guest Anchor with Centralized EoGRE feature for EWC allows you to provide internet services to wireless guest clients, with the help of the Guest Anchor with Centralized EoGRE feature.

For more information, see the chapter Guest Anchor with Centralized EoGRE.

Fast Teardown for a Mesh Access Point

This feature detects the Root Access Point (RAP) uplink failure and addresses the fast teardown of a mesh network when an uplink failure occurs.

The following commands are introduced:

fast-teardown
wireless profile mesh

Note

Fast Teardown for Mesh APs is not supported on Cisco Industrial Wireless (IW) 3702 Access Points.

For more information, see the chapter Mesh Access Points .

Smart Licensing Using Policy: Factory-installed Trust Code

For new hardware orders, a trust code is now installed at the time of manufacturing. Note: You cannot use a factory-installed trust code to communicate with CSSM.

Smart Licensing Using Policy: Support for Trust Code in Additional Topologies

A trust code is automatically obtained in topologies where the product instance initiates the sending of data to CSLU and in topologies where the product instance is in an air-gapped network.

Smart Licensing Using Policy: RUM Report Optimization and Availability of Statistics

RUM report generation and related processes have been optimized. This includes a reduction in the time it takes to process RUM reports, better memory and disk space utilization, and visibility into the RUM reports on the product instance (how many there are, the processing state each one is in, if there are errors in any of them, and so on).

Smart Licensing Using Policy: Support to Collect Software Version Through Smart License Agent

If version privacy is disabled (no license smart privacy version global configuration command), the Cisco IOS-XE software version running on the product instance and Smart Agent version information is included in the RUM report.

Smart Licensing Using Policy: Account Information Included in the ACK and show command outputs

A RUM acknowledgement (ACK) includes the Smart Account and Virtual Account that was reported to, in CSSM. You can then display account information using various showcommands. The account information that is displayed is always as per the latest available ACK on the product instance.

Smart Licensing Using Policy: CSLU Support for Linux

CSLU can now be deployed on a machine (laptop or desktop) running Linux.

Support for Federal Information Processing Standard (FIPS) Mode in Mesh Access Points

From this release onwards, FIPS mode is supported in Mesh Access Points.

Wi-Fi Protected Access 3 Hash-to-Element (H2E) Support for SAE Authentication

The Hash-to-Element (H2E) is new method for PWE (Password Element) generation which is used in the SAE protocol. It is a computationally efficient technique to mitigate side-channel attacks.

The following are the supported PWE methods in the WLAN configuration:

h2e—Hash-to-Element only; disables HnP.
hnp—Hunting and Pecking only; disables H2E.
Both-h2e-hnp—Both Hash-to-Element and Hunting and Pecking support (Is the default option).

The following command has been modified:

security wpa akm sae pwe {h2e | hnp | both-h2e-hnp}

For more information, see the chapter Support for Hash-to-Element for Password Element in SAE Authentication.

Note

Cisco Catalyst 9136 series Access Points do not run Cisco Embedded Wireless Controllers (EWC) and does not join EWC on access points.

Interactive Help

The Cisco Catalyst 9800 Series Wireless Controller GUI features an interactive help that walks you through the GUI and guides you through complex configurations.

You can start the interactive help in the following ways:

By hovering your cursor over the blue flap at the right-hand corner of a window in the GUI and clicking Interactive Help.
By clicking Walk-me Thru in the left pane of a window in the GUI.
By clicking Show me How that is displayed in various parts of the GUI. Clicking Show me How triggers a specific interactive help that is relevant to the context you are in.

For instance, Show me How in Configure > AAA walks you through the various steps for configuring a RADIUS server. Choose Configuration> Wireless Setup > Advanced and click Show me How to trigger the interactive help that walks you through the steps relating to various kinds of authentication.

The following features have an associated interactive help:

Configuring AAA
Configuring FlexConnect Authentication
Configuring 802.1x Authentication
Configuring Local Web Authentication
Configuring OpenRoaming
Configuring Mesh APs

Note

If the WalkMe launcher is unavailable on Safari, modify the settings as follows:

Navigate to Preferences > Privacy.
On the Website tracking field, uncheck the checkbox to disable Prevent cross-site tracking.
On the Cookies and website data field, uncheck the checkbox to disable Block all cookies.

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 17.7.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 DNAC.

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 Series 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

This section describes the interoperability of the controller software with client devices.

The following table describes the configurations used for testing client devices.
