L2/L3 switching with BGP/OSPF routing and stateful firewall capabilities determines this switch's role as a high-performance edge or aggregation layer fabric component. The MikroTik CRS309-1G-8S+IN is a 9-port Cloud Router Switch engineered for data center operators, network engineers, and IT infrastructure teams requiring ultra-high-speed SFP+ connectivity with integrated Layer 3 intelligence. This compact, fanless appliance consolidates switching and routing in a single device, eliminating the need for separate hardware stacks in space-constrained deployments.
Built on the Marvell 98DX3236 ASIC, the CRS309-1G-8S+IN delivers wire-speed performance across eight 10 Gigabit SFP+ ports and one management Gigabit Ethernet port. MikroTik's RouterOS Level 5 license unlocks advanced routing protocols—OSPF, BGP, and MPLS—alongside comprehensive Layer 2 switching features including RSTP, LACP, and IEEE 802.1Q VLAN support. The integrated stateful firewall, NAT, IPsec, and ACL framework provide enterprise-grade security without external appliances. With 160 Gbps switching capacity and 119.05 Mpps forwarding throughput, this device handles mission-critical traffic while consuming just 13 W maximum power and operating entirely fanless. Flexible power input—12–57 V DC or 802.3af/at PoE via the RJ45 port—simplifies integration into diverse infrastructure environments. Part number CRS309-1G-8S+IN ships with 512 MB DDR3 RAM, 16 MB NAND Flash storage, and an 800 MHz ARM processor, delivering responsive management performance for complex configurations.
