Overview
Overview
The Ubiquiti UniFi Enterprise Campus Aggregation is a 1U rack-mount Layer 3 core switch designed to sit at the top of an enterprise campus network — aggregating multiple ECS-24-POE and ECS-48-POE distribution switches into a unified, high-speed campus backbone. With 48 × 25G SFP28 ports and 6 × 100G QSFP28 uplinks, it delivers 3.6 Tbps switching capacity and 1.8 Tbps non-blocking throughput at a forwarding rate of 2.4 billion packets per second.
MC-LAG (Multi-Chassis Link Aggregation) provides active-active redundancy so traffic continues flowing even if one switch fails. Dual hot-swappable 550W PSUs and five hot-swappable fan modules mean the switch can be maintained without taking the network offline. NDAA compliant, CE/FCC/IC certified, and managed through the UniFi Network application with no per-device licensing fees.
Key highlights
- 3.6 Tbps switching capacity, 1.8 Tbps non-blocking throughput
- 48 × 25G SFP28 downlinks for connecting distribution switches and servers
- 6 × 100G QSFP28 uplinks for core or data centre interconnects
- MC-LAG — active-active redundancy between paired aggregation switches
- Dual hot-swappable 550W PSUs and five hot-swappable fans
- Layer 3 managed — DHCP, inter-VLAN routing, and static routing
- Etherlighting™ on all SFP28 and QSFP28 ports
- 1.3″ touchscreen LCM display for on-switch management
- NDAA compliant, CE/FCC/IC certified
Recommended for
- Enterprise campus core — aggregates ECS-24-POE and ECS-48-POE distribution switches into a unified high-speed backbone
- Data centre interconnect — 100G QSFP28 uplinks for high-bandwidth server and storage fabric connections
- High availability networks — MC-LAG pairs two aggregation switches for active-active redundancy with no single point of failure
- Government & regulated environments — NDAA compliant with full Layer 3 routing capabilities

Software
Managed by UniFi Network
The ECS-Aggregation is fully managed through the UniFi Network application — giving network administrators a single interface to configure, monitor, and manage the entire UniFi switching fabric from access layer to core. No per-device licensing fees, with full multi-site management available via UniFi Cloud.
Core management capabilities
- MC-LAG configuration — configure active-active link aggregation between paired aggregation switches for a resilient campus core.
- Port management — configure speed, VLAN assignment, and port profiles per SFP28 and QSFP28 port from the UniFi dashboard.
- VLAN & routing — create and manage VLANs, configure inter-VLAN routing, and define static routes directly in UniFi Network.
- Remote monitoring — real-time port statistics and switch health visible from anywhere via UniFi Cloud.
- Firmware updates — push updates remotely without on-site access.
Requirements
| UniFi Network | Version 8.5.6 or later |
| Hosting | Self-hosted or UniFi Cloud |
| Licensing | None — free with no per-device fees |
