CAPWAP Message Aggregation and other features

Improvements

CAPWAP Message Aggregation

This feature aggregates the CAPWAP control messages of the same type waiting in the queue to be transmitted to the AP.

The following command is introduced:

• capwap aggregation

Cisco Catalyst 9800 Controller Automated Frequency Coordination (AFC) Support for Cisco Catalyst IW9167E Heavy Duty Access Point and Cisco Catalyst IW9167I Heavy Duty Access Point

Cisco Catalyst 9800 Series Wireless Controller serves as an AFC proxy to send the AP information to the AFC system.

Enhancing AP using BLE support on Cisco Catalyst IW9167E and IW9167I Heavy Duty Series Access Points

You can configure an AP as Bluetooth Low Energy (BLE) gateway. Based on the type of AP, there are two types of BLE gateways:

• Base BLE Gateway: This AP type allows you to choose between Transmit mode and Scan mode.
• Advanced BLE Gateway: This AP type comes with an installed IOx application. You use this application to set up floor beacons on the Cisco-partnered Device Manager website.

For Catalyst IW9167E AP, antenna 4 of 2.4 GHz and antenna 1 of 5 GHz shares the antenna with BLE radio.

BLE antenna sharing restrictions:

• When you enable BLE, the 2.4 GHz radio does not support the 4x4 antenna.
• When you enable a 5 GHz single-band antenna in slot 4, the BLE radio is disabled.

FlexConnect Central Web Authentication Central Switching L3 VLAN Override Support

From this release, L3 VLAN override in FlexConnect central web authentication (CWA) is supported for both local and guest clients.

gNMI: SubscribeResponse with sync_response

The sync_response is a boolean field that is part of the SubscribeResponse response message. The sync_response message is sent after the first update message.

gNMI Telemetry Support: Stream Subscriptions with On-Change Mode

This feature introduces gNMI telemetry support on-change subscriptions on the same set of models as other telemetry protocols

IOx Application support on Cisco Catalyst IW9167E and IW9167I Heavy Duty Series Access Points

The Cisco Internet of Experience (IOx) application enables and allows access points to run third-party applications in the CAPWAP mode. To enable IOx, you need an extra memory space up to 50 MB for DRAM and another 100 MB for each IOx application. You can install up to two applications on the AP.

The memory size requirement is based on the following components:

• Actual size of the application
• Run-time data storage
• Bundled IOx infrastructure into access point software (once IOx is bundled into the build, the file size increases by 9 MB)

Israel Domain Changes

From this release, for indoor Wi-Fi 6E APs, Israel and Turkey are moved to the -E regulatory domain and support 6-GHz radio bands. For outdoor APs, Israel is moved from -ROW to the new -I regulatory domain.

Kernel Minidump and Trustzone Upgrade

From this release, the Kernel Minidump and Trustzone Upgrade feature offers a more effective method for diagnosing kernel issues.

The following command is introduced:

• core-dump kernel type

New Countries for 6-GHz Radio Support

From this release, Argentina, Chile, Colombia, Dominican Republic, Israel, Mexico, Singapore, South Africa, Thailand, and Turkey are added to the list of countries that support 6-GHz radio band.

SDA IPv6 Underlay Support

From this release, this feature provides a wireless SDA IPv6 underlay support to enable IPv6-based communications in a fabric domain.

Show Technical Diagnostics for Appliances

From this release, the show tech-support diagnostic command is supported. This command is introduced to display the diagnostic technical support information of a system.

Support for Built-In GPS as Proxy GPS for other 6E APs on Cisco Catalyst IW9167E Heavy Duty Access Point and Cisco Catalyst IW9167I Heavy Duty Access Point

• These APs function as anchor APs with GPS functionality and help in providing geolocation data for other APs that do not have direct GPS signals, in geo-location derivation within the network.
• Additionally, in the absence of GPS coverage, these APs can utilize other 6E APs with GPS to derive their location.
• APs report the geolocation data to the controller via Global Navigation Satellite System (GNSS), ensuring that the network management system has accurate location details for each AP.
• Cisco Catalyst IW9165E Rugged Access Point and Cisco Catalyst IW9165D Heavy Duty Access Point also support this feature.
