Description
High-Density 2.5G PoE+ Switching with 10G Uplinks and Full Cloud Management
The TP-Link Omada SG3218XP-M2 is a rack-mountable L2+ managed switch designed for enterprise, campus, and ISP networks that demand high-throughput connectivity and centralised control. With 16 × 2.5G PoE+ ports, 8 of which deliver PoE+ power, and 2 × 10G SFP+ uplink ports, it provides the bandwidth and power headroom needed for modern Wi-Fi 6/6E access points, IP cameras, VoIP systems, and high-speed workstations — all managed through the Omada SDN platform from a single cloud interface.
Key Features
-
16× 2.5G RJ45 Ports — Full 2.5 Gbps per port for high-throughput connections to Wi-Fi 6/6E APs, NVRs, workstations, and other 2.5G-capable devices
-
8× PoE+ Ports (802.3at) — Powers PoE+ devices including access points, IP cameras, and VoIP phones directly over Ethernet; total PoE budget supports mixed deployments
-
2× 10G SFP+ Uplink Ports — High-speed fibre or DAC uplinks to core switches or routers, with backward compatibility for Gigabit SFP modules
-
Omada SDN Cloud Management — 100% centralised cloud management of switches, access points, and gateways from a single interface, accessible from anywhere via the Omada app or web portal
-
L2+ Static Routing — Enables inter-VLAN routing within the switch for efficient network segmentation without a dedicated router
-
Advanced QoS (L2–L4) — Prioritises voice, video, and critical data traffic by IP/MAC address, TCP/UDP port, or VLAN to ensure smooth, jitter-free performance
-
Comprehensive Security — IP-MAC-Port Binding, ACL (L2–L4), Port Security, DHCP Snooping, Storm Control, DoS protection, and 802.1X authentication with RADIUS/TACACS+ support
-
Full L2 Feature Set — 802.1Q VLAN, Port Mirroring, STP/RSTP/MSTP, LACP Link Aggregation, IGMP Snooping, Loopback Detection, and Cable Diagnostics
-
ISP-Grade Features — 802.3ah OAM, DDM (Digital Diagnostic Monitoring), sFlow, QinQ, L2PT, PPPoE ID Insertion, and IGMP Authentication for service provider deployments
-
IPv6 Ready — Dual IPv4/IPv6 stack, MLD Snooping, IPv6 ACL, DHCPv6 Snooping, and IPv6 Neighbour Discovery for next-generation network readiness
-
Multi-User Management — Role-based access control with multi-level permissions for flexible network operation across teams
-
Enterprise Management Interfaces — Web GUI, CLI, SNMP v1/v2c/v3, RMON, Dual Image, and Dual Configuration for maximum uptime and flexibility
Typical Use Cases
- Enterprise LAN distribution or access layer with high-density Wi-Fi 6/6E AP deployments requiring 2.5G PoE+ connectivity
- Commercial CCTV and IP surveillance installations with multiple PoE-powered cameras and a central NVR
- Education and campus networks requiring centralised Omada SDN management across multiple sites
- Hospitality venues (hotels, resorts) deploying high-density wireless with centralised guest network control
- ISP aggregation and edge deployments leveraging QinQ, OAM, sFlow, and PPPoE ID Insertion
- SME and mid-market offices upgrading from Gigabit to 2.5G for faster wired workstation and NAS connectivity

Frequently Asked Questions
What is the total PoE power budget?
The SG3218XP-M2 provides PoE+ (802.3at) on ports 1–8. For the exact total PoE power budget, refer to the datasheet linked above or the TP-Link product page, as the budget determines how many high-wattage devices (such as PTZ cameras or Wi-Fi 6 APs) can be powered simultaneously.
Can I manage this switch without the Omada cloud?
Yes. The SG3218XP-M2 supports standalone web GUI management, CLI, and SNMP without requiring cloud connectivity. Omada SDN cloud management is optional and adds centralised multi-site control via the Omada app or web portal.
Does it support inter-VLAN routing?
Yes. The L2+ static routing feature enables inter-VLAN routing directly on the switch, allowing traffic to pass between VLANs without a dedicated router — useful for segmenting IoT, camera, and corporate traffic on the same physical infrastructure.
Are the 10G SFP+ ports compatible with standard 1G SFP modules?
Yes. The SFP+ uplink ports are backward compatible with standard 1G SFP modules, giving you flexibility to use existing fibre infrastructure while leaving room to upgrade to 10G when required.
Is this switch suitable for CCTV and IP surveillance deployments?
Yes. The combination of PoE+ ports, IGMP Snooping for multicast video streams, QoS prioritisation, and Omada centralised management makes the SG3218XP-M2 well-suited for commercial IP surveillance installations with multiple cameras and an NVR.
What is DDM (Digital Diagnostic Monitoring)?
DDM allows you to monitor the real-time status of SFP/SFP+ modules inserted into the switch, including temperature, voltage, bias current, and TX/RX power levels. You can also configure alarm and warning thresholds to receive alerts before a module fails.
