Cisco Catalyst 3750X-24P Switch Layer 3 – 24 x 10

Cisco Catalyst WS-C3750X-24P-L – 24-Port Gigabit PoE+ Layer 3 Stackable Switch with LAN Base Software

The Cisco Catalyst WS-C3750X-24P-L is a high-performance, stackable Layer 3 managed switch from the proven Catalyst 3750-X Series, designed for enterprise access and distribution layers. Featuring 24 x 10/100/1000 Ethernet ports with PoE+ (IEEE 802.3at), this switch delivers intelligent power delivery, advanced security, and scalable networking capabilities—all in a compact 1U form factor.

Pre-installed with LAN Base feature set, the WS-C3750X-24P-L supports essential Layer 3 routing (static routes, RIP, EIGRP stub), robust QoS, IPv6, and Cisco StackWise Plus technology for seamless scalability and high availability. Ideal for campuses, branch offices, and mid-sized networks, it provides a cost-effective foundation for converged voice, video, and data applications.

Power over Ethernet Plus (PoE+) for Modern Workspaces

With 370W of PoE+ power, the WS-C3750X-24P-L can simultaneously power:

• IP phones (Cisco, Poly, Yealink)
• Wireless access points (Wi-Fi 5/6)
• IP cameras (including PTZ and HD models)
• Digital signage, IoT sensors, and thin clients

Each port delivers up to 30W, complying with IEEE 802.3at, ensuring compatibility with the latest high-power devices—without requiring midspan injectors or additional cabling.

Note: Total PoE budget is shared across all ports. Intelligent power management ensures critical devices stay powered during overload conditions.

Layer 3 Capabilities with LAN Base Software

Unlike basic Layer 2 switches, the LAN Base image enables essential Layer 3 features, including:

• Static routing between VLANs
• RIP v1/v2 and EIGRP stub for dynamic routing
• IPv6 host and routing support
• Policy-Based Routing (PBR) for traffic engineering
• VLAN ACLs (VACLs) and Router ACLs (RACLs) for granular security

This makes the 3750X ideal for distribution-layer deployments or collapsed core designs in smaller networks—eliminating the need for a separate router in many scenarios.

StackWise Plus: Scalability & Resilience

Cisco’s StackWise Plus technology allows up to 9 Catalyst 3750-X switches to operate as a single logical unit with:

• 64 Gbps bidirectional stack bandwidth
• Cross-stack EtherChannel and QoS
• Unified management (single IP address)
• NSF/SSO (Nonstop Forwarding/Stateful Switchover) for high availability

This simplifies network expansion, reduces management overhead, and provides redundancy—if one switch fails, traffic reroutes automatically.

Security & Manageability

The WS-C3750X-24P-L includes enterprise-grade security features:

• 802.1X authentication with RADIUS integration
• MACsec (802.1AE) for link-layer encryption (on uplinks)
• DHCP Snooping, Dynamic ARP Inspection (DAI), and IP Source Guard to prevent spoofing and man-in-the-middle attacks
• Flexible NetFlow Lite for traffic monitoring

Management options include:

• Cisco IOS CLI for granular control
• SNMPv3 for integration with NMS tools
• Cisco Prime Infrastructure for centralized lifecycle management

Ideal Use Cases

• Enterprise wiring closets powering VoIP, Wi-Fi, and surveillance
• Branch office core/access with integrated routing
• Education and healthcare networks requiring secure, reliable connectivity
• Retail and hospitality deployments with IoT and guest access
• Legacy network upgrades seeking PoE+, stacking, and Layer 3 in one platform
