Questions & Answers
What are Cisco ISR 4000 Series licenses?
Cisco ISR 4000 Series licenses unlock software feature sets and throughput levels on ISR 4000 routers, enabling advanced routing, security, and application services.
Which license tiers are available for Cisco ISR 4000 routers?
Cisco ISR 4000 offers two main tiers—Cisco DNA Essentials and Cisco DNA Advantage—plus optional Performance on Demand and FIPS throughput licenses.
What does the Cisco DNA Essentials license include?
Cisco DNA Essentials provides enterprise routing, basic security, and automation capabilities, ideal for branch connectivity and simplified network operations.
What additional features come with the Cisco DNA Advantage license?
Cisco DNA Advantage adds advanced security, application optimization, SD-WAN, segmentation, and analytics on top of the DNA Essentials feature set.
How do I upgrade my Cisco ISR 4000 license from Essentials to Advantage?
Use Cisco Smart Software Manager or the router CLI to apply a new Advantage entitlement key, then reload the device to activate the upgraded feature set.
What is the Performance on Demand license for ISR 4000?
Performance on Demand dynamically increases router throughput by deploying temporary license tokens, allowing you to scale performance for peak workloads.
How do I activate a Cisco ISR 4000 license?
Register your router in Cisco Smart Software Manager, claim a license entitlement, and install the provided registration token on the ISR 4000 via CLI or web interface.
What is Cisco Smart Licensing and how does it work with ISR 4000?
Cisco Smart Licensing centrally tracks usage and consumption across devices by connecting the ISR 4000 to Cisco’s cloud, simplifying compliance and renewals.
Can I migrate from traditional PAK-based licensing to Smart Licensing on ISR 4000?
Yes. Redeem your Product Authorization Keys (PAKs) in Smart Software Manager and convert them to Smart Account entitlements for cloud-managed licensing.
What is the ISR 4000 FIPS Throughput License?
The FIPS Throughput License enables full hardware encryption throughput on the ISR 4000 in FIPS mode, meeting government security compliance requirements.
How can I check the current license status on my ISR 4000 router?
Run the CLI command 'show license all' to display installed licenses, usage, and expiration dates for all feature sets on the ISR 4000.
What happens if an ISR 4000 license key expires or is non-compliant?
If a license expires or falls out of compliance, the ISR 4000 will revert to a limited feature set or reduced throughput until you renew or correct the entitlement.
Are trial licenses available for Cisco ISR 4000 features?
Yes. Cisco offers 60-day evaluation licenses for DNA Advantage and Performance on Demand, which you can request through your Cisco account representative.
Can I combine multiple license entitlements on one ISR 4000 router?
Yes. Cisco ISR 4000 supports license stacking, allowing you to apply concurrent entitlements for DNA, Performance on Demand, and FIPS throughput on the same device.
How do I purchase additional throughput capacity for ISR 4000?
Order a Performance on Demand license token through your Cisco reseller, then install it via the router CLI to temporarily boost throughput.
Does ISR 4000 licensing support high-availability deployments?
Yes. In HA configurations, each ISR 4000 node requires the same license entitlements to ensure seamless failover and consistent feature availability.
