Deploying network infrastructure inside a hypervisor introduces unique virtualization challenges. Use these troubleshooting baselines if you encounter issues. 1. Throughput Capped or License Violations
To install a regular license, you must obtain a Product Authorization Key (PAK) and generate the license on the Cisco Software Licensing portal (https://www.cisco.com/go/license).
If you are starting a fresh greenfield virtual deployment, it is highly recommended to deploy the Catalyst 8000V OVA instead of the legacy CSR 1000V. The Catalyst 8000V offers modernized licensing via Cisco Smart Licensing Using Policy, vastly improved SD-WAN integration, and higher throughput scaling capabilities optimized for modern multi-cloud data centers. Transitioning existing setups involves migrating configurations to the new Cat8000V platform, as configuration syntax remains highly consistent due to both platforms utilizing Cisco IOS-XE. cisco csr1000v ova
