# Topology Property Reference

> Aviatrix Cloud topology property reference

The following tables describe the properties of managed and unmanaged resources
displayed in the map at Cloud Fabric > Topology.

## Spoke Gateway VPC/VNet Property Descriptions

You can filter your VPC/VNet topology in the topology map using the following
fields for both Aviatrix-managed and unmanaged VPCs and VNets (second from
innermost circle of the topology map).

| **VPC/VNet Property** | **Description** |
| - | - |
| Name | The name of the VPC or VNet (cannot be determined for unmanaged resources) |
| Type | The Topology construct type (in this case, VPC or VNet) |
| Account Name | The CSP Account associated with this VPC or VNet |
| Cloud | The CSP that this VPC or VNet belongs to (AWS, Azure, etc.) |
| Region | The CSP region where the VPC or VNet is located |
| VPC/VNet ID | The unique identifier for the VPC or VNet |
| VPC/VNet CIDR | List of the CIDRs associated with the VPC or VNet |
| NAT Gateways | List of the VPC or VNet NAT Gateways |
| Virtual Machines | Number of VMs (instances) the VPC or VNet contains |
| S2C Connections | List of the VPC or VNet Site2Cloud tunnels |
| Peer Connections | List of the VPC or VNet peer connections |
| Status | Up/Down: Denotes whether the VPC or VNet is running (cannot be determined for unmanaged resources) |
| Managed | true/false: Indicates whether or not this VPC or VNet is managed by an Aviatrix Gateway |

## Subnet Property Descriptions

You can filter your Subnet topology in the topology map using the following
fields for subnets that are Aviatrix-managed or unmanaged (third from outermost
circle on the topology map).

| **Subnet Property** | **Description** |
| - | - |
| Name | The name of the subnet (cannot be determined for unmanaged resources) |
| Subnet CIDR | The CIDR of the subnet |
| Type | The Topology construct type (in this case, Subnet) |
| Interface ID | The ID of the gateway interface the subnet is on (cannot be determined for unmanaged resources) |
| Subnet ID | The ID of the instance's subnet |
| Cloud | The CSP that this VPC or VNet belongs to (AWS, Azure, etc.) |
| Account Name | The CSP Account associated with this VPC or VNet |
| Region | The CSP region in which the instance is located |
| VPC/VNet ID | The ID of the instance's VPC or VNet |
| VPC/VNet Name | The name of the instance's VPC or VNet (cannot be determined for unmanaged resources) |
| Tags | The tags assigned to the selected resource |
| Managed | true/false: Indicates whether or not this VPC or VNet is managed by an Aviatrix Gateway |

## Virtual Machine Property Descriptions

You can filter your Virtual Machine topology in the topology map using the
following fields for virtual machines that are in Aviatrix-managed or unmanaged
VPCs or VNets (second from outermost circle on the topology map).

| **Virtual Machine Property** | **Description** |
| - | - |
| Name | The name of the instance |
| Type | The Topology construct type (in this case, Virtual Machine) |
| Region | The CSP region in which the instance is located |
| Instance ID | ID of the image from which the instance was built |
| Cloud | The CSP that this VPC belongs to (AWS, Azure, etc.) |
| Account Name | The CSP Account associated with this VM |
| VPC/VNet ID | The ID of the instance's VPC or VNet |
| VPC/VNet Name | The name of the instance's VPC or VNet |
| Subnet ID | The ID of the instance's subnet |
| Instance Status | Denotes whether the instance is running (cannot be determined for unmanaged resources) |
| Managed | true/false: Indicates whether or not this VPC or VNet is managed by an Aviatrix Gateway |
| Public IP | The Public IP of the instance (cannot be determined for unmanaged resources) |
| Private IP | The private IP of the instance (cannot be determined for unmanaged resources) |
| Public DNS Name | The Public DNS name of the instance (cannot be determined for unmanaged resources) |
| Private DNS Name | The Private DNS name of the instance (cannot be determined for unmanaged resources) |
| Launch Time | The timestamp when the VM was launched (cannot be determined for unmanaged resources) |
| Image ID | ID of the image from which the instance was built (cannot be determined for unmanaged resources) |
| Instance Size | The size of the instance (e.g. "t2.micro,") |
| Hypervisor | The instance's hypervisor (cannot be determined for unmanaged resources) |
| Kernel | The Linux kernel version of the Gateway instance (cannot be determined for unmanaged resources) |
| Tags | The tags assigned to the selected resource |
| High Performance | yes/no: Denotes whether the gateway has high performance encryption active |
| Source NAT | true/false: Denotes whether Source NAT is active on this gateway |
