Viewing a Subnet Topology Map

View a map that shows a visual representation of a subnet topology.

The subnet view provides resource information about the instances, load balancer, FSS, OKE clusters in a subnet. Whether you want to get an idea of the resources in the subnet or details about a specific resource, this view provides the flexibility to achieve that. The search capability using name, IP address or OCID comes handy to find a resource and get to the resource page in single click.

    1. While viewing a regional map, click a VCN. Wait briefly for the network map to generate.
    2. If you need to change compartment, click CHANGE COMPARTMENT and select a different compartment.
    3. Click any VCN resource on the map, and in the resource summary click either View VCN routing map or View VCN security map. While viewing one of these map modes, you can easily switch to the other map mode.
    4. Click any subnet resource on the map, and in the resource summary click either View subnet inventory map or View subnet security map. While viewing one of these map modes, you can easily switch to the other map mode.
    5. Click any resource on the map (the resource changes color to indicate the selection) to view basic information for that item in the right-hand column. The details presented vary depending on the component you selected.
    6. Elements in the control bar include, from leftmost to rightmost:
      • Map: Displays the selected subnet map.
      • To find a resource by name, enter the name in the search window. When a match is found and selected, the view zooms in to that resource.
      • Download Icon Export Map Data: Exports a zip file containing a high resolution .png map of the resources in the current region and compartment, and a .pdf file containing a lower resolution version of the map plus resource data (such as route tables). This PDF only includes resource information for elements seen in the map at the time of export.
      • Screen Refresh Icon Refresh: updates the view in the main map window. The view is refreshed every three minutes, but if a change was made since the last refresh you can manually trigger a refresh of the diagram.
      • Filter Icon Filter: Allows you to turn on and off the filters used in the current view.
      • Legend Icon Legend: Displays the symbols used in the map and their meaning.
      You can navigate back to the Network Topology regional map by clicking on the name of the region in the control bar, or by selecting one of the connected VCNs and clicking Go to Region Map in the resource information.

  • Use the subnet-topology get command and required parameters to get a virtual network topology for a subnet in the current region and specified compartment:

    oci network subnet-topology get --compartment-id compartment_OCID ... [OPTIONS]

    For a complete list of flags and variable options for CLI commands, see the CLI Command Reference.

  • Run the GetSubnetTopology operation to get a virtual subnet topology for the current region and specified compartment.

    The response body will contain a single SubnetTopology resource, which contains the following resources showing relationships between entities in the subnet:
