Cisco DevNet Sandbox Free Virtual Lab

The Cisco DevNet Sandbox is a free online tool where you can test and develop various Cisco technologies, i.e. Cloud, Security, SD WAN, etc. without owning or setup any Cisco hardware or virtual server. You just register or use your existing CCO login.

There are a lot of Sandbox virtual labs to choose from. This is useful if you need to test a new IOS-XE or NX-OS feature without blowing up your production network. You can also do a Proof of Concept (POC) or Proof of Value (POV) without having to ask from your Cisco Account Manager for a loan hardware. It's also a great learning tool for those studying their Cisco certifications, i.e. CCNA, CCNP, etc.


Click a specific Sandbox Lab. In this case I chose the Cisco Modeling Labs (CML) Enterprise > click Reserve.

The Sandbox lab setup takes around 10 minutes to complete. You can check the time left on the Setup green icon on the top right corner. You'll receive an email about the Sandbox lab chosen and a download link for the Cisco AnyConnect VPN client software installer. I used Cisco AnyConnect version 4.x in my laptop.

Once the Setup is finished, the Sandbox Setup changed to Active (top right) and nodes will have a green dot. You'll also receive another email informing the Sandbox lab is ready and gives you a temporary username/password login.


Copy/paste the AnyConnect VPN address/URL > click Connect > type the username and password provided in the email.

 

Open an SSH client > select the Service: Telnet > type the Sandbox component IP address > click OK. I used TeraTerm in this case.


There's also a PDF network diagram you can view or download in the Instructions section.
