MikroTik CRS310-8G+2S+IN 8-Port 2.5G Cloud Router Switch with 2x 10G SFP+ (RouterOS & SwOS)

MikroTik CRS310-8G+2S+IN — 8-Port 2.5G Cloud Router Switch with 2x 10G SFP+ for ISP & HomeLab Networks

The MikroTik CRS310-8G+2S+IN is a compact, fanless 8-Port 2.5 Gigabit Cloud Router Switch with 2x 10G SFP+ uplink ports, delivering multi-gigabit switching performance in a desktop form factor. Running either MikroTik RouterOS or SwOS, this switch is equally at home as a Layer 3 ISP core switch, a WISP tower aggregator, or a high-performance home lab switch — all from the same hardware platform.

With 8x 2.5Gbps RJ45 ports and a 36 Gbps non-blocking switching fabric, the CRS310-8G+2S+IN eliminates the bottlenecks of standard Gigabit access switches, making it the right upgrade for ISP NOCs, multi-gig Wi-Fi 6 deployments, NAS and hypervisor backbones, and fibre ISP distribution layers across Uganda and East Africa.

RouterOS vs SwOS — Which Mode Should You Use?

The CRS310-8G+2S+IN ships with both operating systems and you can switch between them at any time:

• RouterOS v7 — choose this for full ISP-grade deployments requiring BGP, OSPF, MPLS, PPPoE server, RADIUS, firewall, QoS, and VPN. Ideal for ISP core switches and NOC infrastructure.
• SwOS — choose this for simple Layer 2 managed switching with VLAN, RSTP, and bandwidth limiting via browser GUI. Ideal for access layer aggregation where routing is handled upstream.

Ideal Use Cases for Uganda & East Africa ISPs

• ISP NOC core switching — connect edge routers, billing servers, NMS platforms, and monitoring tools at 2.5G with 10G uplinks to your fibre backbone
• WISP tower aggregation — aggregate multiple sector radio backhaul links at 2.5G with 10G uplink to your fibre POP
• Wi-Fi 6 multi-gig access layer — connect Wi-Fi 6 APs that support 2.5G uplinks to eliminate the bottleneck at the switch port
• NAS & hypervisor backbones — connect Proxmox, VMware, TrueNAS, and Synology servers at 2.5G for faster VM migration and NAS throughput
• ISP billing server infrastructure — dedicated 2.5G switching for RADIUS, billing, NMS, and monitoring VLANs in your NOC
• Home lab & enterprise lab networks — multi-gig switching for network engineers testing ISP configurations before production rollout

ISP Billing & Subscriber Management Integration

In RouterOS mode, the CRS310-8G+2S+IN supports PPPoE server, RADIUS authentication, and per-subscriber bandwidth queuing, making it a combined core switch and subscriber gateway for small-to-medium ISPs. Integrate it with our purpose-built ISP billing and subscriber management platform for automated PPPoE session control, invoicing, and real-time bandwidth reporting:

Frequently Asked Questions

Q: What makes the CRS310-8G+2S+IN different from a standard Gigabit switch?

All 8 access ports run at 2.5Gbps — 2.5x faster than 1G — plus two 10G SFP+ uplinks, and it runs full RouterOS with BGP, OSPF, PPPoE, RADIUS, QoS, and VLAN. No standard Gigabit switch can match that feature set.

Q: Should I use RouterOS or SwOS?

RouterOS for full ISP routing (BGP, OSPF, PPPoE, RADIUS, firewall). SwOS for simple Layer 2 VLAN and bandwidth management via browser. You can switch between modes anytime without new hardware.

Q: Can it run a PPPoE server for ISP subscriber management?

Yes — in RouterOS mode. Pair it with our ISP billing platform and the MikroTik hEX S router for a complete subscriber management stack.

Q: Does it support 10G SFP+ fibre uplinks?

Yes — both SFP+ ports support SMF, MMF, and DAC at 10G. MikroTik-branded SFP+ modules recommended for full compatibility.

Q: Is it available in Uganda?

Yes. NetEdge Supplies stocks it at UGX 726,000. Delivery to Kampala, Entebbe, Jinja, Mbarara, and Gulu. Bulk ISP pricing on request.

Q: Can it be powered via PoE?

Yes — Port 1 accepts passive PoE (16–57V) input, ideal for tower and field cabinet deployments without a separate DC power run.
