Brief Introduction of Cisco Catalyst 3750-X Series Switches
Feb 15 , 2023 1349

Cisco Catalyst 3750-X series, as stackable switches, are enterprise-grade products. These switches provide continuous connectivity, scalability, security, energy efficiency and ease of operation through innovative features such as Cisco StackPower, IEEE 802.3at Enhanced Power over Ethernet (PoE+) configuration, optional network modules, redundant power supplies, and Media Access Control Security(MACsec), etc. The Cisco Catalyst 3750-X Series with StackWise Plus technology provides scalability, ease of management, and investment protection for growing business needs. The Cisco Catalyst 3750-X and 3560-X series enable applications such as IP phone, wireless, and video for a borderless network experience that increases productivity.

The features of Cisco Catalyst 3750-X and 3560-X Series Switches list as below,


  • 24 and 48 10/100/1000 PoE + and non- PoE models

  • Optional 4 Gigabit Ethernet(GbE) SFP or 2 10GbE SFP+ uplink network modules

  • The first PoE +, 30W on all ports, 1 rack unit form factor 

  • Dual redundant, modular power supplies and fans

  • Hardware-based encryption for MACsec 

  • IPv4 and IPv6 routing, multicast routing, advanced quality of service, and security features in hardware

  • Enhanced Limited Lifetime Warranty, advanced hardware replacement, and 90-day Cisco Technical Assistance Center support

  • Enhanced Cisco Energy Wise to measure and report actual power consumption of PoE devices and reduce network energy consumption to optimize operating costs

  • USB Type A and Type B ports, and out-of-band Ethernet management port.

    In addition to the features described above, Cisco Catalyst 3750-X switches also provide,

  • Cisco StackPower Technology: the first innovative feature to share power among stack members in this field

  • Cisco StackWise Plus Technology: 64 Gbps throughput for ease of use and recovery

  • Investment protection: backwards compatible with all other models of Cisco Catalyst 3750 Series Switches

Switch configuration

All switch models can be configured with 4 optional network modules. These PoE + and non-PoE switch models offer LAN Base or IP Base feature sets. The IP Services feature set will be available as an upgrading option at the time of order or by licensing at a later time. These GE SFP switch models offer IP Base or IP Services feature sets.

In addition to the IP Base and IP Services feature sets, the Cisco Catalyst 3750-X comes with a new LAN Base feature set. All Cisco Catalyst 3750-X and 3560-X Series Switches offer these three feature sets:

  • LAN Base: Enhanced Smart Services

  • IP Base: Essential Business Services

  • IP Services: Enterprise Services

The LAN Base feature set provides enhanced intelligent services, including comprehensive Layer 2 functions and Layer 3 static routing functions, and can support up to 255 VLANs. In addition to all LAN Base functions, the IP Base feature set provides basic enterprise services and can support 1K VLANs. IP Base also supports routed access and OSPF for routed access dynamic routing, StackPower (only available on Catalyst 3750-X series), MACsec and new Cisco Service modules. The IP Services feature set provides a complete set of enterprise services, including advanced Layer 3 features such as Enhanced Interior Gateway Routing Protocol, Open Shorter Paths Priority, Border Gateway Protocol, Protocol Independent Multicast and IPv6 routing such as OSPFv3 and EIGRPv6. All software feature sets support advanced security, QoS and management functions.

Cisco Catalyst 3750-X Series Switches with the LAN Base feature set can only be stacked with other Cisco Catalyst 3750-X Series LAN Base Switches. Mixed stacking with LAN Base switches with IP Base or IP Services feature set is not supported.

The most demanding applications are supported by Cisco Catalyst 3750-X Series Switches. These enterprise-class stackable switches offer the following advantages:

  • Providing industry-leading security

  • Defensing against malicious behavior with Flexible NetFlow

  • Data confidentiality ensured by MACSec layer 2 encryption

  • Providing identity-based access control via TrustSec

  • First-class patency

  • Providing self-healing capabilities and sub-second failover with StackWise Plus

  • Improving power supply continuity with StackPower

  • Supporting uninterrupted communication with redundant power supplies and cooling fans 

  • Minimizing downtime with hot-swappable power supplies, cooling fans, and network modules

  • Optimal Quality of Service

  • Prioritizing business-critical traffic such as video with strict priority queuing

  • Verifying network readiness and simplifying troubleshooting with Mediatrace and traffic simulators

  • Reducing operating costs

  • Reducing operating costs and improving business sustainability with Cisco EnergyWise power management capabilities

  • Simplifying deployment, configuration, and control with Cisco Catalyst Intelligent Operations

  • Recycling unused power with intelligent power management

  • Maximizing increase investment protection

  • Smooth transition to IPv6 with comprehensive hardware support

  • Minimizing the disruption required to upgrade the software platform or add new features

  • Leading the way in PoE aspect

  • Up to support 48 PoE + ports, providing up to 30 watts of power per port
