At the aggregation layer, a single uplink becoming saturated affects every device behind it, so the switch chosen there has to have real headroom rather than just enough capacity for today's load. The Pro XG Aggregation is built around that requirement: full Layer 3 routing lets it handle inter-VLAN traffic and static routes without a separate router, and its DC power backup input allows it to stay online through a primary power failure, which matters far more at the core than at the edge.
- 32x 25G SFP28 ports (25G/10G/1G): Every port can run at 25G, 10G, or 1G, so the switch can aggregate a mix of newer 25G access switches and existing 10G equipment without needing separate hardware for each speed.
- 1.6 Tbps switching capacity, 800 Gbps non-blocking throughput: All 32 ports are rated to pass traffic at full line rate simultaneously, giving the aggregation layer headroom as access-layer traffic grows.
- 1.2 Bpps forwarding rate: High packet-processing capacity keeps latency low even with dozens of 25G links active at once.
- Layer 3 routing (inter-VLAN, static routes, DHCP server/relay): Handles routing between VLANs directly, reducing the need for a dedicated router at the core.
- DC Power Backup input: Connects to a UniFi Smart Power RPS for redundant power, protecting against the single point of failure a core switch would otherwise represent.
- 32,000-entry MAC address table: Supports networks with a large number of connected devices without table exhaustion.
- 1.3" LCM touchscreen with Etherlighting: Displays live port status and speed, and illuminates ports to speed up physical troubleshooting on a fully populated rack.
Within Ubiquiti's aggregation lineup, the Pro XG Aggregation is the model built for pure 25G density, thirty-two SFP28 ports, rather than the mixed 10G/25G port layout of the Hi-Capacity Aggregation. That makes it the more direct fit where a network's access layer is already moving to 25G uplinks and the aggregation point needs to scale with it.
The Simplifi Advantage
Because a 25G aggregation switch sits at a point of the network where downtime affects everyone behind it, sourcing it through Ubiquiti's official channel matters. Simplifi Networks, an authorized Ubiquiti distributor for Kenya and Uganda, supplies genuine Pro XG Aggregation hardware and can advise on RPS-based power redundancy and Layer 3 configuration for teams building out a 25G core.
