Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction to Cisco Sensor Connect for IoT Services

The Cisco Sensor Connect for IoT Services solution enables delivery of advanced BLE capabilities over Cisco Catalyst Wireless infrastructure. The key component of this solution is the IoT Orchestrator which is a Cisco IOx application that can be deployed on any existing Cisco Catalyst 9800 Wireless Controller platforms running software version Cisco IOS-XE 17.15.3 and later. With the Cisco Sensor Connect for IoT Services solution, you have capabilities to securely onboard and control BLE devices, and consume data telemetry using the Message Queuing Telemetry Transport (MQTT).

Note:

●     Cisco Catalyst 9115 AP is supported with Sensor Connect for IoT Services feature for scanning and advertising. Cisco does not recommend using this AP model for delivering high density, latency-sensitive, or mission critical BLE use cases due to known hardware performance limitations.

●     For information on the VIDs for the access points, see the How to Identify Affected Products section in the Field Notice.

Supported Platforms

●     Cisco Catalyst 9800-L Wireless Controller

●     Cisco Catalyst 9800-40 Wireless Controller

●     Cisco Catalyst 9800-80 Wireless Controller

●     Cisco Catalyst CW9800M Wireless Controller

●     Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllers

Software Features

New Software Features 1.1

Feature

Description

Support for MQTT Message Batching

To improve network efficiency and achieve high MQTT throughput in scale scenarios, the IoT Orchestrator application supports MQTT message batching. As a result, a new protobuf message called DataBatch has been introduced. It acts as a wrapper for multiple data subscription messages, and each DataBatch message can contain multiple DataSubscription messages.

The partner application that consumes MQTT messages from the IoT Orchestrator must update the data application protocol buffer from the Pre-GA Release prototype to the GA Release prototype.

For information on the Data Application Protocol Buffer (Pre-GA Release), see the https://github.com/ietf-wg-asdf/asdf-nipc/blob/nipc-asdf-01/proto/data_app.proto.

For information on the Data Application Protocol Buffer (GA Release), see the https://github.com/ietf-wg-asdf/asdf-nipc/blob/cisco-iot-orchestrator-1.1/proto/data_app.proto.

Support for Multiple MQTT Data Receivers with Shared Subscriptions

A Shared Subscription is a feature in MQTT that allows multiple clients (subscribers) to share the workload of receiving messages from a single topic.

It also helps achieve high MQTT throughput by preventing a single subscriber client from becoming a bottleneck.

For more information, see the Cisco Sensor Connect for IoT Services Programmability Guide.

Support for Application Events

Application events apply to use cases that require BLE device connection. If a BLE device is connected and any of the following scenarios occur:

• IoT Orchestrator application restarts

• Cisco Catalyst 9800 Wireless Controller reloads

• Cisco Catalyst 9800 Wireless Controller HA switchover

Then the partner application must register for the application_events topic to receive notifications such as Application Restarted or Application Stopped.

For more information, see the Cisco Sensor Connect for IoT Services Programmability Guide.

Bug ID

Headline

CSCwh56683

The BLE module of the AP experiences a memory leak when switching from Spaces Sensor Connect for IoT Services (IoT Orchestrator) to the Cisco Spaces Connector setup

CSCwo00821

 

The IoT Orchestrator application fails to start after upgrading or reloading the system

Note:      This bug affects only the C9800-L model and is intermittent occurring infrequently.

CSCwo08759

The GRPC connection status on AP is not reported correctly to the wireless controller after a sudden flap of the AP uplink even though the connection is up from the AP

 

CSCwo66172

Application Hosting Conflict: Guest Shell and IoT Orchestrator co-existence issue in Cisco Catalyst 9800 Wireless Controller

CSCwo66956

Cisco Catalyst 9800-L Wireless Controller may crash if more than 6 VirtualPortGroup interfaces are configured

CSCwo52685

The GRPC connection status on AP is not reported correctly to the wireless controller after a switchover or full stack reload

AP does not send the AP inventory message due to the BLE MAC address being unavailable, as the IoT radio was disabled on the AP via the IoT Orchestrator.

Workaround:

To address this issue, you can follow these steps:

1.     Reload the AP.

2.     Manually enable the IoT radios by running the following command: test iot ble poweron
