The USW-Aggregation-Pro is a fully managed Layer 3 switch featuring four 25G SFP28 ports and 28 10G SFP+ ports. It is equipped with a 1.3-inch touchscreen and supports high-bandwidth links to enable link aggregation for increased capacity and better availability. The USW-Aggregation-Pro is managed via the UniFi Controller and the mobile app, allowing you to easily build, scale, and monitor your enterprise networks. The four SFP28 ports do not support mixed speeds in 25 Gbps mode. Once one of the SFP28 ports is configured in 25 Gbps mode, the others will also be limited to 25 Gbps. The SFP28 ports only support mixed speeds when all ports are set to 1 Gbps or 10 Gbps.
