You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity.

The 1th example of the child command would be to use it to 'ex 1   update an existing active directory connector using the kubernetes api', the syntax is: az arcdata ad-connector update --name arcadc  --k8s-namespace arc  --primary-ad-dc-hostname azdc01.contoso.local --secondary-ad-dc-hostname "azdc02.contoso.local, azdc03.contoso.local"  --nameserver-addresses 10.10.10.11,10.10.10.12,10.10.10.13 --dns-replicas 2  --prefer-k8s-dns false  --use-k8s. The 2th example of the child command would be to use it to 'ex 2   update an existing active directory connector through azure resource manager  arm', the syntax is: az arcdata ad-connector update --name arcadc --resource-group rg-name --data-controller-name dc-name --primary-ad-dc-hostname azdc01.contoso.local --secondary-ad-dc-hostname "azdc02.contoso.local, azdc03.contoso.local" --nameserver-addresses 10.10.10.11,10.10.10.12,10.10.10.13 --dns-replicas 2 --prefer-k8s-dns false.

The parameter '--dns-replicas' is optional. the number of copies for dns proxy service.. The parameter '--domain-service-account-secret' is optional. the name of the kubernetes secret containing the credentials for the pre-created active directory account with permissions to create and manage accounts in the given ou.. The parameter '--k8s-namespace -k' is optional. the kubernetes namespace containing active directory connector.. The parameter '--nameserver-addresses' is optional. list of active directory dns server ip addresses separated by ',' (e.g. 10.10.10.11,10.10.10.12,10.10.10.13).. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--prefer-k8s-dns' is optional. use kubernetes dns server responses over the active directory dns server responses for ip address lookup. allowed values are 'true' or 'false'.. The parameter '--primary-ad-dc-hostname' is optional. the hostname of the primary ad domain controller.. The parameter '--resource-group -g' is optional. the azure resource group of the arc data controller associated with this active directory connector..
