This section provides the purpose, elements, and actions performed on the Cloud Networks pages.

​
Purpose

The VPC/VNets & Subnets page displays and manages all Virtual Private Clouds (VPCs) and Virtual Networks (VNets) across cloud providers, showing their configuration details, network information, associated subnets, and resources. You can create new VPC/VNets from this page.

​
Elements

Cloud Networks: VPC/VNets & Subnets
  • + VPC/VNet button: Opens the Create VPC/VNet dialog to create a new VPC/VNet.
  • VPC/VNets & Subnets table: Shows a list of all VPC/VNet instances with their details including name, cloud provider, region, availability zones, account, IP address CIDR, virtual machine count, and management status. Columns such as ID and Billing ID may be hidden until you use Columns.
  • Actions menu: Bulk action Create SmartGroup for the selected VPC/VNets or subnets (disabled until at least one row is selected; select up to 20 rows).
  • Filter button: Button to show or hide filter options for the table.
  • Columns button: Button to select which columns to display in the table.
  • Download button: Button to download VPC/VNets & Subnets data.
  • Search box: Search box for filtering VPC/VNets and subnets in the table.
  • Default View dropdown: Dropdown that shows the active view (for example, Default View). Use it to select a saved view or click Manage Views to manage views.
  • Clear button: Button inside the view dropdown to clear the current view selection.
  • Open button: Button inside the view dropdown to open the list of saved views.
  • Save As New View button: Button to save the current view configuration as a new view. Appears only after you change the filters, columns, or sort order.
  • More Options button: Button next to Save As New View that opens a menu with Discard Changes. Appears only after you change the filters, columns, or sort order.
  • Table row checkboxes: Checkboxes for selecting individual VPC/VNets or subnets.
  • Table header checkbox: Checkbox in table header to select all VPC/VNets or subnets.
  • Delete action: Removes an individual deletable VPC/VNet row (shown for eligible Aviatrix-managed VPC/VNets without virtual machines).
  • Total count display: Text showing total number of VPC/VNets (e.g., “Total 18 VPC/VNets”).
  • Refresh status: Text showing last refresh time with a refresh button.
  • Check CIDR Overlap button: Opens the CIDR overlap workflow so you can compare VPC/VNet CIDR ranges in your inventory and find conflicts before they affect routing or peering.

​
Actions

To view VPC/VNets and subnets:
  1. Go to Cloud Resources > Cloud Networks.
  2. The VPC/VNets & Subnets page appears with the table listing all VPC/VNet instances.
  3. Optionally, use Search, Filter, Columns, or the Default View dropdown to customize the view.
  4. Optionally, use Open, Save As New View, or Clear to manage view settings.
  5. Optionally, click Download to download data or use the refresh control to refresh the table.
  6. Select rows with Table row checkboxes or Table header checkbox to use Actions for bulk operations, or use Delete action on an eligible row.
The table shows Name, VPC/VNet, Cloud, Region, Availability Zones, Account, IP Address CIDR, Virtual Machines, Cloud Tags, SmartGroups, and Aviatrix Managed for each VPC/VNet by default. Use Columns to show ID, Billing ID, or other fields.

Parameter Details

To create a new VPC/VNet:
  1. Go to Cloud Resources > Cloud Networks.
  2. Click + VPC/VNet to open the Create VPC/VNet dialog.
  3. Enter Name (must begin with a letter; letters, numbers, underscores, and dashes only; max 30 characters).
  4. Select Cloud (AWS, Azure, GCP, OCI, or Alibaba), Account, and Region.
  5. Specify VPC/VNet CIDR (labeled VPC/VNet IPv4 CIDR when IPv6 allocation fields are shown) and optionally click Check to validate the CIDR.
  6. If shown, configure IPv6 Allocation (AWS, Azure, and GCP when IPv6 support is enabled on the Controller).
  7. Select VPC Function (Default or Transit + FireNet).
  8. Optionally, expand Advanced Settings (Subnet Size, Number of Subnet Pair(s); Azure may include Resource Group).
  9. Click Save to create the VPC/VNet.
The new VPC/VNet appears in the VPC/VNets & Subnets table.
For GCP, Auto Assignment (External or Internal) is the recommended IPv6 allocation method.

​
Parameter Details

Use Check CIDR Overlap on the VPC/VNets inventory page to see whether any IP Address CIDR blocks used by your VPCs or VNets overlap. Overlapping CIDRs can break or complicate connectivity, peering, and firewall policy design.To run a CIDR overlap check:
  1. Go to Cloud Resources > Cloud Networks > VPC/VNets & Subnets.
  2. Click Check CIDR Overlap.
  3. Review Background Polling (Enabled or Disabled). Click Enable or Disable to turn automatic discovery of VPC/VNet CIDRs on or off.
  4. In VPC/VNet CIDR, enter the CIDR to check, then click Check.
  5. (Optional) Click Refresh CIDR Data to re-scan CIDRs across onboarded cloud accounts (confirm when prompted).
  6. Click Close when finished.
Check results appear in the dialog (success, warning, or error message). Some conflicts may open a separate details dialog.
