There is a command group 'az_networkcloud_trunkednetwork'. This group of commands could 'manage trunked network'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. 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. Use --debug for full debug logs.'. This group contains a child command 'az_networkcloud_trunkednetwork_create'.The syntax is: az networkcloud trunkednetwork create --extended-location
                                      --isolation-domain-ids
                                      --name
                                      --resource-group
                                      --vlans
                                      [--interface-name]
                                      [--location]
                                      [--no-wait {0, 1, f, false, n, no, t, true, y, yes}]
                                      [--tags]. The 1th example of the child command would be to use it to 'create or update trunked network', the syntax is: az networkcloud trunkednetwork create --resource-group "resourceGroupName" --name "trunkedNetworkName" --extended-location name="/subscriptions/subscriptionId/resourceGroups/resourceGroupName/providers/Microsoft.ExtendedLocation/customLocations/clusterExtendedLocationName" type="CustomLocation" --location "location" --interface-name "eth0" --isolation-domain-ids "/subscriptions/subscriptionId/resourceGroups/resourceGroupName/providers/Microsoft.ManagedNetworkFabric/l2IsolationDomains/l2IsolationDomainName" "/subscriptions/subscriptionId/resourceGroups/resourceGroupName/providers/Microsoft.ManagedNetworkFabric/l3IsolationDomains/l3IsolationDomainName" --vlans 12 14 --tags key1="myvalue1" key2="myvalue2". The parameter '--extended-location' is required. It is used to the extended location of the cluster associated with the resource.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--isolation-domain-ids' is required. It is used to the list of resource ids representing the network fabric isolation domains. it can be any combination of l2isolationdomain and l3isolationdomain resources.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--name --trunked-network-name -n' is required. It is used to the name of the trunked network.. The parameter '--resource-group -g' is required. It is used to name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--vlans' is required. It is used to the list of vlans that are selected from the isolation domains for trunking.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--interface-name' is optional. the default interface name for this trunked network in the virtual machine. this name can be overridden by the name supplied in the network attachment configuration of that virtual machine.. The parameter '--location -l' is optional. the geo-location where the resource lives  when not specified, the location of the resource group will be used.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--tags' is optional. resource tags.  support shorthand-syntax, json-file and yaml-file. try "??" to show more..
