Cisco ASR1000 MACsec 40G Per Port License | Smart Version — FLSA1-MACSEC40G-SV

Secure 40G uplinks on Cisco ASR1000 platforms with a per-port MACsec license designed for encrypted transport at the edge and across critical WAN paths. This Smart Version license enables organizations to extend link-layer protection where traffic sensitivity, compliance requirements, or inter-site trust boundaries demand stronger control. Because the entitlement is applied per port, teams can align spend with actual deployment needs instead of overcommitting to broad platform licensing. That makes it a practical fit for environments where only specific high-value links require MACsec coverage. It also supports cleaner procurement and lifecycle management in Cisco-centric estates, where license precision matters as much as technical fit. For infrastructure teams protecting branch aggregation, campus interconnects, or provider handoffs, this license helps preserve throughput while adding encryption at the interface level. It is a targeted way to raise the security posture of ASR1000 deployments without introducing unnecessary hardware changes or broader software complexity. Ideal For Encrypting 40G WAN uplinks on Cisco ASR1000 routers Securing campus or data center interconnect links Applying MACsec to selected high-value circuits Meeting link-layer encryption requirements in Cisco-managed networks Why This Product 1 Per-port licensing avoids paying for unused encryption capacity 2 40G MACsec coverage suits high-throughput Cisco ASR1000 links 3 Smart Version delivery fits Cisco license management workflows 4 Targeted entitlement is better than broad platform licensing for selective deployments
