Cisco MacSec HW Right-to-Use per 400G for 8000 Series — Per-400G License | MACsec, RTU — MACSEC-400G-RTU-2

Protect high-speed interconnects by enabling hardware MACsec on Cisco 8000 Series platforms using a per-400G right-to-use license. The MACSEC-400G-RTU-2 SKU grants entitlement to enable MacSec encryption on eligible 400G ports, letting teams satisfy link-level confidentiality and integrity requirements at line rate without forklift upgrades. Licensing at the 400G granularity aligns procurement to port capacity: buy only the entitlements you need for spine, leaf, or aggregation links. Implementation is operationally straightforward—apply the RTU license to the targeted interface and configure MacSec policies in the device control plane. For infrastructure leaders, this SKU reduces project risk by preserving existing hardware investments and providing a vendor-supported path to encrypted fabric links required for regulated traffic or inter-data-center confidentiality policies. Ideal For Encrypt east-west data center fabric links between spine and leaf on 400G ports Protect inter-data-center 400G links to meet regulatory confidentiality requirements Enable secure peering and transit on 400G external links License selective ports for staged deployment to control cost and scope Why This Product 1 Per-400G licensing avoids bulk port purchases vs. per-chassis licensing 2 Right-to-Use preserves existing hardware vs. purchasing new MACsec-capable line cards 3 Hardware MACsec supports line-rate encryption vs. CPU-based approaches 4 Vendor RTU entitlement simplifies compliance vs. unmanaged third-party encryptors
