The Cisco WS-C3750X-12S-E is a fixed-configuration Layer 3 Ethernet switch from Cisco's Catalyst 3750-X family with 12 SFP fiber ports that provide dense gigabit fiber connectivity in a single chassis. It offers Layer 3 routing capabilities, enabling inter-VLAN routing and routing-based traffic management within enterprise networks, making it suitable for distribution or edge deployments where fiber-based links are required. The model is identified as V05 and is specifically described as a 12-port gigabit fiber switch, emphasizing its high port density. Its 12 SFP ports are designed to support fiber-based links between switches, servers, or distribution devices in campus or small-to-medium data-center edge environments. This combination of routing capability and port density makes it a practical choice for organizations seeking a Cisco Catalyst solution with a compact footprint for fiber-connected networking.
