Cisco switch C 3750 24FS- S

The Cisco Catalyst 3750 24FS-S is a managed Layer 3 stackable Ethernet switch featuring 24 Fast Ethernet ports with integrated switch fabric technology, designed for enterprise network infrastructure requiring high availability and intelligent traffic management. Network administrators and IT professionals deploy this switch in medium to large-scale corporate environments, data centers, and campus networks where reliable switching performance and VLAN segmentation are critical operational requirements. This switch solves the challenge of managing complex network traffic patterns while maintaining low latency and high throughput in demanding production environments.

Product Overview

The Cisco Catalyst 3750 24FS-S operates as a Layer 3 intelligent switch with integrated routing capabilities, enabling it to perform both switching and routing functions simultaneously. The device utilizes Cisco's proprietary switching architecture with a distributed forwarding engine across its line cards, allowing wire-speed performance across all 24 Fast Ethernet ports. Each port operates at 100 Mbps full-duplex, delivering consistent 2.4 Gbps aggregate throughput. The switch supports Cisco StackWise technology, enabling up to 9 units to be stacked together with a dedicated 32 Gbps backplane connection, creating a single logical switching entity with simplified management and redundancy capabilities.

This model distinguishes itself through advanced Quality of Service (QoS) mechanisms, comprehensive VLAN support up to 4094 VLANs, and integrated security features including Access Control Lists (ACLs) and port-based authentication. The switch incorporates 32 MB of Flash memory and 128 MB of DRAM, providing sufficient resources for IOS image storage and runtime operations. Built-in redundancy features such as Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP) ensure network stability and prevent switching loops in complex topologies. The device operates with a mean time between failures (MTBF) exceeding 500,000 hours, demonstrating enterprise-grade reliability for mission-critical deployments.

• Manufacturing and Industrial Networks requiring deterministic QoS for real-time control systems while maintaining separate VLANs for operational technology (OT) and information technology (IT) networks

How to Use

Begin by physically installing the Cisco Catalyst 3750 24FS-S in a standard 19-inch equipment rack using the provided mounting brackets, ensuring adequate ventilation space above and below the device. Connect the power cable to a reliable power source with appropriate surge protection, and verify the power LED illuminates green indicating normal operation. Connect your network devices to the 24 Fast Ethernet ports using standard Cat5e or Cat6 Ethernet cables, and establish an out-of-band management connection via the console port (RJ-45) using a terminal emulation program such as PuTTY or Hyper Terminal at 9600 baud rate.

Access the switch's command-line interface (CLI) through the console connection and enter privileged EXEC mode using the enable command. Configure the management IP address by entering global configuration mode and assigning an IP address to VLAN 1 using the interface vlan 1 command followed by ip address [IP] [netmask]. Set up your VLAN structure by creating additional VLANs with the vlan [number] command and assigning ports to VLANs using the switchport access vlan [number] command in interface configuration mode. Enable StackWise functionality if stacking multiple units by connecting the dedicated stack ports with StackWise cables and configuring stack priority levels. Configure spanning tree parameters to prevent switching loops, enable SSH for secure remote management, and implement QoS policies by defining traffic classes and assigning priority queues. Save your configuration using copy running-config startup-config to ensure settings persist after device restart.

Frequently Asked Questions

What is the difference between the 3750 24FS-S and other 3750 models?

The 3750 24FS-S provides 24 Fast Ethernet ports with full Layer 3 capabilities and StackWise support. Other variants include the 3750 48TS-S with 48 ports and the 3750G with Gigabit Ethernet ports. The FS designation indicates Fast Ethernet with standard switching performance, making it ideal for access layer deployments where Gigabit speeds are not yet required but intelligent switching is essential.

Can I stack multiple 3750 24FS-S switches together?

Yes, the 3750 24FS-S supports StackWise technology allowing up to 9 switches to be stacked together using dedicated StackWise cables. Stacked switches operate as a single logical entity with a unified management interface, simplified configuration, and automatic failover capabilities. Each stack connection provides 32 Gbps of bandwidth, and the stack can be managed through any member switch, providing redundancy if one switch fails.

What are the power requirements for the 3750 24FS-S?

The Cisco Catalyst 3750 24FS-S requires approximately 150 watts of power under normal operating conditions. It operates from standard AC power (100-240V, 50-60Hz) and should be connected to a reliable power source with surge protection or uninterruptible power supply (UPS) for critical network deployments. Power consumption may vary slightly based on port utilization and connected device count.

Does the 3750 24FS-S support Power over Ethernet (PoE)?

The standard 3750 24FS-S does not include integrated PoE capability. However, Cisco offers PoE modules that can be installed in compatible slot configurations on certain 3750 variants. If PoE functionality is required, consider the 3750 POE models or deploy external PoE injectors for specific ports supporting VoIP phones or wireless access points.

What is the maximum number of VLANs supported?

The 3750 24FS-S supports up to 4094 VLANs, allowing extensive network segmentation for large enterprise environments. VLAN 1 is the default VLAN and cannot be deleted, while VLANs 2-4094 can be created and configured according to your network architecture requirements. Each VLAN operates as a separate broadcast domain, enabling traffic isolation and enhanced security.
