The Cisco Catalyst 3750X 12 is a powerful and compact enterprise-class switch, designed specifically for networks that require high-speed fiber connectivity, advanced routing, and rock-solid reliability. Featuring 12 Gigabit SFP ports and an optional 4 x 1G SFP uplink module (via C3KX-NM-1G), this switch delivers flexible performance in data centers, branch offices, and campus environments.

Engineered with Cisco’s StackWise Plus technology and robust Layer 3 capabilities, the Cisco Catalyst 3750X 12 enables simplified network scaling and centralized management, making it a perfect fit for growing enterprise networks.

Key Features of Cisco Catalyst 3750X 12

✔️ 12 SFP-Based GE Ports with Optional Uplinks

The switch includes 12 built-in 1Gb SFP ports, providing the flexibility to support a variety of fiber or copper transceivers. Additionally, the device supports an optional C3KX-NM-1G module, offering 4 extra 1Gb SFP uplink ports, which are ideal for backbone or aggregation connections.

✔️ Advanced Layer 3 Switching

The Cisco Catalyst 3750X 12 is a full Layer 3 switch, supporting dynamic routing protocols like OSPF, EIGRP, and RIP, as well as static routing, policy-based routing, and IPv6 support. This ensures seamless communication between VLANs and improved traffic optimization across your network.

✔️ No PoE – Optimized for Fiber

As a non-PoE model, the Cisco Catalyst 3750X 12 is optimized for fiber-based connections where Power over Ethernet is not needed. This makes it ideal for environments where end devices (like servers or storage systems) don’t require inline power.

Scalability and Redundancy

With StackWise Plus support, you can stack up to 9 switches as one logical unit, greatly simplifying management and increasing redundancy. If a switch in the stack fails, the rest of the stack continues to operate seamlessly—ensuring minimal downtime and excellent business continuity.

The Cisco Catalyst 3750X 12 also supports redundant power supplies, with hot-swappable options to keep your network always online.

Security Features

Security is a top priority with the Cisco Catalyst 3750X 12. The switch supports:

• 802.1X Port Authentication

• DHCP Snooping

• Dynamic ARP Inspection

• IP Source Guard

• Access Control Lists (ACLs)

These features help safeguard your network from unauthorized access, man-in-the-middle attacks, and IP spoofing.

Energy Efficiency

The Cisco Catalyst 3750X 12 leverages Cisco EnergyWise technology to monitor and optimize energy usage across the network. Its efficient power design helps reduce operational costs without compromising performance, especially in fiber-only environments.

Management and Integration

The switch supports advanced management tools:

• Cisco IOS Software (CLI)

• SNMP and RMON

• NetFlow Lite

• Cisco Prime Infrastructure

• Cisco DNA Center Compatibility

These features make it easy to automate, monitor, and troubleshoot network operations from a single pane of glass.
