Cisco ASR5K-03-CSXDNSS= Enterprise DNS Snooping License | Cisco Licensing — ASR5K-03-CSXDNSS=

Gain deeper DNS insight across the Cisco ASR 5000 platform with an enterprise-wide license built for DNS snooping and reverse DNS lookup. This entitlement adds visibility into name resolution activity, helping network teams trace traffic behavior, validate policy decisions, and accelerate root-cause analysis when application access depends on DNS performance. For service providers and large-scale network operators, DNS telemetry is often the difference between guessing and knowing. By enabling DNS snooping and reverse lookup capabilities at enterprise scope, this license supports more informed operations across distributed environments where subscriber density, traffic volume, and troubleshooting demands are high. It is a practical fit for teams that need to correlate network events with DNS activity, improve operational clarity, and reduce time spent chasing ambiguous session data. Because it is an enterprise-wide license, it is suited to organizations standardizing visibility across a broader deployment rather than adding point features one node at a time. Ideal For Service provider operations teams monitoring DNS activity across ASR 5000 deployments Network engineers correlating subscriber sessions with reverse DNS results Troubleshooting teams investigating application access issues tied to name resolution Large enterprises standardizing DNS visibility across distributed infrastructure Why This Product 1 Enterprise-wide entitlement instead of node-by-node licensing 2 Adds DNS snooping and reverse DNS lookup capabilities 3 Built for Cisco ASR 5000 environments 4 Targets operational visibility rather than hardware expansion
