The error is due to Command Runner in Cisco DNA Center being designed to support only the execution of ‘show’ commands or other read-only commands. When an engineer tries to execute configuration commands or any commands that are not read-only, they will be blocklisted as these are not supported by Command Runner. This ensures that Command Runner is used strictly for retrieving information without making any configuration changes to devices. References := (Automating Cisco Enterprise Solutions Official Cert Guide)

The provided exhibit likely shows a POST request setup in an API testing tool like Postman, with JSON formatted data specifying commands for configuring a network device interface. These commands are not supported by Command Runner as it does not allow configuration changes, only read operations.

YANG-push telemetry data offers several benefits over traditional data collection methods such as SNMP polling. One significant advantage is that it uses less bandwidth because it sends updates only when there’s a change in subscribed data, rather than repeatedly polling all devices at regular intervals regardless of changes. This makes it more efficient and reduces unnecessary network traffic. Additionally, YANG-push telemetry scales better than SNMP because it can handle more frequent updates from a large number of devices without overwhelming the network or management systems. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

 The statement ‘D’ is used to assign the list of interfaces from the JSON response to the variable ‘interfaces’. This allows the script to iterate over each interface and print the IP addresses of all loopback interfaces.
