Ubiquiti PRO-XG-AGGREGATION | UniFi Pro XG Aggregation Switch

A professional-grade Layer 3 aggregation switch for high-capacity SFP28 uplinks, suited to larger UniFi deployments where access-layer switches need a central aggregation point.

Why this one

• SFP28 connectivity sits above standard SFP+ aggregation, which means it keeps pace with access-layer switches that have already outgrown conventional uplink speeds.
• Layer 3 switching lets you route between VLANs at the switch itself rather than sending that traffic up to a gateway, which reduces latency on inter-VLAN traffic in larger flat-floor or multi-building deployments.
• Etherlighting on each port gives you per-port status at a glance across the chassis — useful when you're tracing a specific uplink in a populated rack without pulling a laptop.
• Staying within the UniFi ecosystem means it's managed through the same Network console as your gateways, access points and access-layer switches, with no separate management plane to operate.

Good fit if you're running a UniFi network at a scale where access-layer switches are feeding high-capacity uplinks into a central rack, and you need a single aggregation point that handles routing, VLAN segmentation and high-throughput inter-switch links without leaving the UniFi controller.

Worth considering something else if your deployment is small enough that a UniFi gateway with SFP+ uplinks handles everything in one box — the USW-PRO-AGGR suits mid-scale aggregation needs and sits in a lower price band if the SFP28 port density here exceeds what you'll actually use.

What you'll also need

Compatible SFP28 or SFP+ transceivers or DAC cables to connect your access-layer switches, a UniFi gateway or Cloud Gateway to act as the network controller, rack space and appropriate power, and structured cabling or fibre from each access-layer switch to the aggregation point.
