Cisco ISR 4431 4GE 3NIM 8G Flash 4G DRAM | Enterprise Router — CON-L14OS-UCSS3260

Keep critical branch services online with a router built for sustained WAN edge performance. Cisco ISR 4431 brings 4 Gigabit Ethernet interfaces, 3 NIM slots, 8 GB of flash, and 4 GB of DRAM into a compact platform designed for enterprise routing, segmentation, and secure connectivity. This configuration is well suited for teams that need more than basic branch forwarding. The additional memory and modular expansion support help the platform handle richer services, more complex traffic patterns, and future interface requirements without forcing an immediate refresh. That makes it a stronger fit for environments where uptime, consistency, and lifecycle planning matter. For infrastructure teams standardizing on Cisco ISR platforms, this model offers a practical balance of performance and expandability. It is a credible choice for branch offices, distributed sites, and network edge deployments where reliability and service continuity justify the investment. Ideal For Branch office WAN edge routing Distributed site network aggregation Secure enterprise connectivity at remote offices Modular branch infrastructure expansion Why This Product 1 More modular than fixed-port branch routers 2 Better suited for expansion with 3 NIM slots 3 Stronger memory profile with 4 GB DRAM 4 Designed for enterprise WAN edge use
