The Cisco Catalyst 8000V Edge Software offers a 30-day free trial that includes a Cisco DNA Advantage subscription with a throughput of 250 Mbps. This trial can be accessed on platforms like Amazon Web Services or Microsoft Azure.

To run the Catalyst 8000V, your server should have an Intel Nehalem or AMD Barcelona CPU with a clock frequency above 2.0 GHz, 4 to 16 GB of memory, and at least 8 GB of disk space. It also requires specific virtual CPUs and network interfaces depending on whether you're using VMware ESXi or Red Hat KVM.

After the 30-day trial period, you can continue using the Catalyst 8000V by purchasing a license through your Cisco account manager or a Cisco reseller.
