About the Cisco Catalyst 3850 WS-C3850-12S-S Cisco Catalyst switch
The Cisco Catalyst 3850 WS-C3850-12S-S delivers 160 Gbps switching capacity and a forwarding rate of 130.95 Mpps, providing line-rate performance for demanding enterprise environments. This managed, stackable Layer 3 switch features 12 x SFP (Gigabit Ethernet) ports and supports up to 4 x SFP+ (10 Gigabit Ethernet) uplink ports via module slot expansion, making it ideal for organizations requiring flexible connectivity at scale. Built on Cisco's proven Catalyst 3850 series architecture, the WS-C3850-12S-S runs Cisco IOS XE with IP Base software imaging, supporting advanced routing protocols including OSPF, EIGRP (stub), and RIP, with optional BGP capability via IP Services licensing.
Network engineers will appreciate the StackWise-480 stacking technology, which enables up to 9 stack members and delivers an aggregate stack bandwidth of 480 Gbps for seamless multi-switch deployments. The switch maintains a 32,000-entry MAC address table and supports 4,094 VLANs with full IPv6 support, ensuring carrier-grade scalability across modern enterprise networks. Modular, field-replaceable power supplies are available in 350W AC, 715W AC, 1100W AC, and 350W DC configurations, with redundant power supply options to maximize uptime.
