Cisco-Catalyst WS-C3850-12S-S
The Cisco Catalyst WS-C3850-12S-S is a 12-port Gigabit Ethernet Layer 3 managed switch designed for enterprise campus, aggregation, and fiber-based access networks. It provides 12 × 1G SFP fiber ports, advanced Layer 2/Layer 3 switching, StackWise-480 technology, enterprise security, QoS, and Cisco IOS XE software.
Description
The Cisco Catalyst WS-C3850-12S-S is part of the Cisco Catalyst 3850 Series, an enterprise-class switching platform designed to provide secure, scalable, and high-performance connectivity for campus and business networks.
The switch provides 12 Gigabit Ethernet SFP interfaces, making it particularly suitable for fiber-based network deployments. These interfaces can be used to connect aggregation switches, distribution infrastructure, servers, remote network segments, or other fiber-enabled devices.
Unlike copper-based Catalyst 3850 models, the WS-C3850-12S-S is optimized for deployments where fiber connectivity is required at the access or aggregation layer. Compatible SFP transceivers can be selected according to the required fiber type, distance, and network speed.
The switch runs Cisco IOS XE, providing integrated Layer 2 and Layer 3 networking capabilities. It supports VLANs, trunking, STP/RSTP/MST, EtherChannel, IPv4/IPv6 routing, OSPF, EIGRP, VRF-Lite, QoS, multicast, and advanced network security.
The Catalyst 3850 platform supports StackWise-480, allowing multiple compatible switches to operate as a single logical switching system. This provides up to 480 Gbps of stack bandwidth, improving scalability, simplifying management, and increasing network resiliency.
The -S designation identifies the IP Base software license level for this model, while advanced routing and security functionality can depend on the installed software release and licensing configuration.
The WS-C3850-12S-S is housed in a 1U rack-mount chassis, making it suitable for enterprise server rooms, network cabinets, distribution environments, and campus infrastructure.
