ISR4461/K9 Use Case
Branch Office SD-WAN and Secure Connectivity with Cisco ISR 4461
In a national retail chain, deploying Cisco ISR 4461 with 4 onboard GE ports, 3 NIM slots for 4G LTE backup, 1 ISC slot for content security, and 3 SM slots for SFP uplinks—backed by 8 GB flash, 2 GB data-plane DRAM, and 4 GB control-plane DRAM—enables up to 4 Gbps of encrypted SD-WAN traffic. Benefit: 40% reduction in MPLS costs, sub-50 ms failover, and centralized management via Cisco DNA Center.
Data Center Edge Security and VPN Aggregation
A financial services data center uses Cisco ISR 4461 to consolidate multi-site VPN, firewall, and intrusion prevention. Four onboard GE ports handle LAN trunking, 3 NIM slots host encryption accelerators, 1 ISC slot runs Firepower services, and 3 SM slots provide SFP uplinks. With 8 GB flash, 2 GB data-plane DRAM, and 4 GB control-plane DRAM, it delivers 3 Gbps of SSL VPN and IPS throughput. Outcome: 50% rack-space savings, PCI-DSS compliance, and unified policy enforcement.
IoT Edge Aggregation and Segmentation for Smart Manufacturing
In a smart factory, Cisco ISR 4461 serves as an IoT edge gateway using 4 onboard GE ports for sensor networks, 3 NIM slots for wireless modules, 3 SM slots for fiber-optic machine links, and 1 ISC slot for edge analytics. Equipped with 8 GB flash, 2 GB data-plane DRAM, and 4 GB control-plane DRAM, it processes real-time telemetry and enforces segmentation. Outcome: 30% faster anomaly detection, enhanced OT security, and a 25% boost in production uptime.
