Cisco WS-C3850-12XS-E Switch – High-Performance 10G Aggregation with IP Services

The Cisco WS-C3850-12XS-E is an advanced, enterprise-grade stackable Layer 3 switch designed for high-bandwidth enterprise environments. As part of the Cisco Catalyst 3850 Series, this model offers 12 ports of 10 Gigabit SFP+, built-in IP Services software, and integrated wireless controller functionality—all in a 1U rack-mountable form factor.

Key Features and Benefits

The Cisco WS-C3850-12XS-E combines high-speed 10G connectivity, robust Layer 3 routing, and wireless convergence. Its 12-port 10G SFP+ configuration delivers efficient data transmission for bandwidth-heavy applications. The integrated IP Services image enables advanced routing features including OSPF, EIGRP, BGP, and IPv6.

The built-in wireless LAN controller allows unified wired and wireless network management, supporting up to 100 wireless access points and 2,000 clients per switch (or 3,600 APs in a stack). With Cisco StackWise-480, the switch supports up to 480 Gbps of stacking bandwidth, ensuring scalability and high availability.

Additional features include modular uplink flexibility, redundant power supply support, hot-swappable fans, comprehensive QoS, and enterprise-grade security (TrustSec, MACsec), making it ideal for modern enterprise network environments.

1. High-Speed 10G Access with Enterprise Routing Features

Equipped with 12 x 10Gbps SFP+ fiber ports, this switch fits perfectly in aggregation or distribution layers. It runs Cisco IOS XE with the IP Services feature set, supporting advanced routing protocols like OSPF, EIGRP, BGP, PBR, and IPv6. It also offers 1 modular uplink slot supporting up to 4 additional 10G uplink ports.

2. Integrated Wireless LAN Controller for Full Network Convergence

The built-in wireless controller supports up to 100 APs and 2,000 clients per switch, or 3,600 APs in a stack. This enables centralized management of both wired and wireless infrastructure, enhancing network visibility and efficiency.

3. StackWise-480 Scalability and Resilient Hardware Design

Cisco StackWise-480 enables up to 480 Gbps stacking bandwidth across multiple switches. The WS-C3850-12XS-E supports redundant power supplies, hot-swappable fans, and modular uplinks, ensuring uptime and performance in mission-critical scenarios.

4. Advanced Security, QoS, and Management
