Cisco ASR 9000 MACsec 40G RTU License | ASR 9000, Security — L-A9K-MACSEC-40=

Secure 40G transport links on Cisco ASR 9000 infrastructure with a MACsec right-to-use license built for environments where traffic confidentiality matters. This spare PAK is intended for teams extending encryption capabilities across carrier, enterprise edge, and aggregation deployments without changing the underlying platform. MACsec adds link-layer protection to help safeguard data in motion across trusted network segments. For organizations carrying sensitive workloads, regulated traffic, or inter-site backbone flows, licensing the feature on supported ASR 9000 systems can be the difference between basic connectivity and controlled, policy-aligned transport. Because this is a right-to-use license, it fits operational models that need precise feature activation rather than hardware replacement. That makes it a practical choice for infrastructure teams standardizing security controls across installed ASR 9000 assets while keeping procurement aligned to the exact capability required.
