Cisco ASR 900 10GE Port MACsec License | Enterprise Network Security — FLSASR900-10G-MS=

Secure high-speed transport links on Cisco ASR 900 platforms with a per-port MACsec license for 10GE interfaces. This entitlement is built for organizations that need to protect data in motion at the network edge and across critical uplinks while preserving the performance profile of the routing platform. It is a practical fit for enterprise WAN, campus aggregation, and service-provider-style edge designs where link encryption matters. The per-port model gives infrastructure teams a precise way to license only the interfaces that need MACsec, which helps keep deployments controlled and procurement aligned to actual port usage. That matters when you are standardizing security across multiple sites or rolling out encryption in phases. Instead of overbuying capacity, you can map licensing directly to the 10GE ports carrying sensitive traffic. For teams comparing options, this license stands out because it extends the value of the ASR 900 platform rather than forcing a platform change. It supports a cleaner security posture on existing infrastructure, with licensing that is easy to track, scale, and renew as network requirements grow. Ideal For Encrypting 10GE uplinks on Cisco ASR 900 routers Securing aggregation links between enterprise sites Adding MACsec to sensitive transport paths without platform replacement Phased rollout of link-layer encryption across distributed networks Why This Product 1 Per-port licensing is more precise than platform-wide security bundles 2 MACsec adds link-layer protection without changing the ASR 900 architecture 3 Designed for 10GE ports rather than generic Ethernet interfaces 4 Fits phased enterprise rollouts where only selected links need encryption
