Cisco WS-C3750X-12S-S Layer 3 Gigabit Ethernet Managed Switch

The Cisco WS-C3750X-12S-S is a 1U, rack-mountable managed fiber Ethernet switch in the Cisco Catalyst 3750-X Series that provides Layer 2 and Layer 3 switching with high-speed fiber connectivity for enterprise campuses and data centers. It directly provides 12 Gigabit Ethernet SFP ports for fiber links, supports Cisco StackWise Plus for unified management and redundancy, and offers up to 160 Gbps switching capacity with a forwarding rate of up to 65.5 Mpps. Uplink flexibility comes from Cisco C3KX module support (SFP/SFP+), while management is via CLI, SNMP, or Web-based interfaces, making it suitable for deployment at distribution or fiber aggregation layers to interconnect servers, storage networks, and other distribution switches.
