Microsoft.Network.VirtualNetworkCombo UI element

A group of controls for selecting a new or existing virtual network.

UI sample

When the user picks a new virtual network, the user can customize each subnet's name and address prefix. Configuring subnets is optional.

Microsoft.Network.VirtualNetworkCombo new

When the user picks an existing virtual network, the user must map each subnet the deployment template requires to an existing subnet. Configuring subnets in this case is required.

Remarks

  • If specified, the first nonoverlapping address prefix of size defaultValue.addressPrefixSize is determined automatically based on the existing virtual networks in the user's subscription.
  • The default value for defaultValue.name and defaultValue.addressPrefixSize is null.
  • constraints.minAddressPrefixSize must be specified. Any existing virtual networks with an address space smaller than the specified value are unavailable for selection.
  • subnets must be specified, and constraints.minAddressPrefixSize must be specified for each subnet.
  • When you create a new virtual network, each subnet's address prefix is calculated automatically based on the virtual network's address prefix and the respective addressPrefixSize.
  • When you use an existing virtual network, any subnets smaller than the respective constraints.minAddressPrefixSize are unavailable for selection. Additionally, if specified, subnets that don't have at least minAddressCount available addresses are unavailable for selection. The default value is 0. To ensure that the available addresses are contiguous, specify true for requireContiguousAddresses. The default value is true.
  • Creating subnets in an existing virtual network isn't supported.
  • If options.hideExisting is true, the user can't choose an existing virtual network. The default value is false.
