Cisco L-FLA1-MACSEC100G= ASR1000 MACsec 100G Per Port License | Enterprise — L-FLA1-MACSEC100G=

Keep sensitive traffic protected at line rate on Cisco ASR 1000 infrastructure with a per-port MACsec 100G license. Designed for teams that need encryption on high-capacity links, this spare e-delivery entitlement supports secure transport without changing the physical network design. For enterprise WAN, edge, and aggregation deployments, MACsec helps preserve confidentiality on links that carry critical application, voice, and control-plane traffic. The per-port model gives you precise control over where encryption is applied, which is useful when only specific uplinks or interconnects require protection. That makes it easier to align security spend with actual traffic paths. As a spare license, it fits environments that maintain standby entitlements for continuity, replacement, or operational flexibility. Cisco licensing is often chosen when procurement teams need a clear path for asset tracking and support alignment across installed infrastructure. This license is a practical fit for organizations standardizing on ASR 1000 platforms and looking to secure 100 GbE connections without overbuying capacity they do not need.
