CXTM Topologies

CXTA and CXTM leverage the unicon framework of device control libaries to define how connections should be established to the devices in the testbed, such as routers, switches, and servers. The unicon framework stores the device connection parameters (protocols, IP addresses, ports, etc) and credentials in a testbed file in YAML format.

In this section, you'll 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 New Topology File field.

Step 3 - Create Topology File

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

Step 4 - Save Topology File

After pasting in the New Topology File above:

1. Click Save As

Step 6 - Name Topology File & Save

Step 7 - 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 8 - Return to your project's Test Cases page

Continue to the next section to edit your test cases to run in your ACI fabric.
