Known issues and workaround


Set-SCVMSubnet -RemovePortACL job completes in VMM without removing portACL association from NC VMSubnet object, due to which Remove-PortACL job fails with NC Exception that it is still in use. 


Below script can be added as workaround to remove the ACL from NC: 

Import-Module NetworkController 

 $uri = "<NC FQDN or IP>" # Replace with the URI of the Network Controller REST IP or FQDN 

$cred = Get-Credential # Provide NC Admin credentials 

 #Identify the virtual network that contains the subnet. 

$vnet = Get-NetworkControllerVirtualNetwork -ConnectionUri $uri -ResourceId "Fabrikam_VNet1" -Credential $cred 

 #Identify the subnet for which the ACL needs to be removed. 

$vnet.Properties.Subnets[0].Properties = $vnet.Properties.Subnets[0].Properties | Select-Object -Property * -ExcludeProperty AccessControlList 


New-NetworkControllerVirtualNetwork -ResourceId "Fabrikam_VNet1" -ConnectionUri $uri –Properties $vnet.Properties -Credential $cred
