RJ45 ports serve access-layer copper connections; SFP/SFP+ ports enable flexible 1G/10G uplinks; SFP28 delivers 25G for modern data centers; QSFP+ and QSFP28 support high-density 40G/100G spine–leaf fabrics. Ethernet switch port types define the performance, scalability, and architecture of modern networks. You can add a compatible SFP transceiver module to the SFP port of Ethernet. Ethernet switches are integral components of networking infrastructure, facilitating the efficient transfer of data across devices. This guide explains Ethernet switch ports, categorizes the main types, and outlines their applications, helping network professionals and IT. Cisco switch ports are categorized by their physical hardware interfaces (such as RJ45 copper, fiber-optic SFP uplinks, and console ports), their bandwidth speed capacities (Gigabit, 10G, 100G), and their logical operating modes. 1Q trunk ports are supported •Tunnel Ports: designed for service providers who carry traffic of multiple.
