Task 1: Install Services

Setup the ACI Simulator

Access the session overview and select the "acisim" option, then click "VM Console."

A new browser window will open with a setup wizard. Configure only these essential settings:

IP address: 198.18.134.11/18 Gateway: 198.18.128.1 Password: C1sco12345

Return to the Windows RDP session and open Chrome. Refresh the page to see the APIC login screen.

🥳 Congratulations! The first step is complete! 🥳
