CXTM Topologies

As previously mentioned, CXTM offers multiple options to create topology files. Now that you have leveraged the CXTM Devices page to create a topology file, you will learn how to create your own topology file through the Topologies page.

Step 1 - Navigate to Topologies

Step 2 - Review Topology Pane

Upon navigating to Topologies, you will see a blank topology file. If you had a pre-existing topology, you could open it using the Open button.

Step 3 - Create Topology File

1. Copy the following connection information into your New Topology File.

testbed:
  name: LTROPS-2711 Topology
  credentials:
    default:
      username: admin
      password: cisco.123

        via: ssh
      ssh:
        protocol: ssh
        ip: 10.15.103.21
      rest:
        class: rest.connector.Rest
        protocol: https
        ip: 10.15.103.21

      ssh:
        protocol: ssh
        ip: 10.15.103.23
      rest:
        class: rest.connector.Rest
        protocol: https
        ip: 10.15.103.23

    type: switch
    os: nxos
    platform: n9k
    connections:
      defaults:
        via: ssh
      ssh:
        protocol: ssh
        ip: 10.15.103.24
      rest:
        class: rest.connector.Rest
        protocol: https
        ip: 10.15.103.24
  L3:
    type: switch
    os: nxos
    platform: n9k
    connections:
      defaults:
        via: ssh
      ssh:
        protocol: ssh
        ip: 10.15.103.25
      rest:
        class: rest.connector.Rest
        protocol: https
        ip: 10.15.103.25
  L4:
    type: switch
    os: nxos
    platform: n9k
    connections:
      defaults:
        via: ssh
      ssh:
        protocol: ssh
        ip: 10.15.103.26
      rest:
        class: rest.connector.Rest
        protocol: https
        ip: 10.15.103.26

Step 4 - Save Topology File

After pasting in the New Topology File above:

1. Click Save As

Step 5 - Name Topology File & Save

In the Save As pop-up:

1. Name your topology file: LTROPS-2711 Topology
2. Then click Save

Step 6 - Confirm Topology Pane Changes

After saving, you will notice that the Topologies pane changes with different options now enabled, such as Save for future updates to manage your topology file.

Step 7 - Return to your project's Test Cases page

From your project's Topologies page:

1. Click on the Project LTROPS-2711 button




2. Click on VIEW TEST CASES

Continue to the next section to begin work with CXTM automation files, also called Job Files.
