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.

CGNA is a subsystem running on IOS which provides connectivity and manageability with network management system like FND and IOT Operations Dashboard. Complete documentation sets for IoT Field Network Director and IoT Industrial Network Director can be found in the following links:
The majority of features are implemented on the IR1800 including basic profile, execution profile, heartbeat profile, and firmware download. Some features like bspatch will not be imported on the IR1800 due to the limitation on the IOS image.
CGNA has four different profiles for different use cases. They are:
Profile - This is the basic profile. It can be configured to support tunnel provision, registration, and periodic update.
Execution profile - This can be configured to execute CLI commands
Heartbeat profile - This can be configured to send heartbeat messages
Transport profile - This can be configured to provide different transport protocol for the basic profile to use. Currently only supports WebSocket.
CGNA also provides CLIs for resumable image retrieval from network management system and simple SNMP server for redirecting events to WebSocket connection.
Traditional IOS provided the WebSocket service in the IOSd kernel. Polaris IOS-XE moves the WebSocket service out of the IOSd kernel for improved performance. The websocket version will be upgraded to 3.2.3.
