Core Architecture and Performance Specifications

At its heart, the WS-C3750V2-24TS-E is built on Cisco's StackWise technology, a revolutionary backplane that unites individual switches into a single, logical, unified entity. This foundational capability is key to its value proposition.

StackWise Technology: Unified Management and Redundancy

Cisco's proprietary StackWise technology interconnects up to nine physical Catalyst 3750 switches using high-speed stack cables, creating a cohesive system with a unified 32 Gbps stacking interconnect. This architecture allows network administrators to manage the entire stack as a single unit—with one IP address, one configuration file, and one routing instance. From a redundancy perspective, StackWise provides enhanced resiliency; if the master switch in the stack fails, a subordinate switch automatically assumes the master role, minimizing network disruption and simplifying operational recovery.

Performance Metrics and Forwarding Capacity

The switch leverages a forwarding bandwidth of up to 38.7 Gbps and a packet forwarding rate of 26.8 Mpps (million packets per second). This ensures wire-speed performance across all ports, preventing bottlenecks at the network edge. The integrated switching fabric distributes bandwidth across the stack, ensuring consistent performance even as additional switches are added to meet growing demands.

Port Configuration and Connectivity Details

The "24TS" designation explicitly outlines its port makeup: 24 dedicated Ethernet ports and 2 Small Form-factor Pluggable (SFP) uplink ports.

24 x 10/100BASE-TX Copper Ports

These twenty-four RJ-45 ports support both 10 Mbps and 100 Mbps Ethernet speeds, making them ideal for connecting a wide array of legacy and modern devices such as desktop PCs, IP phones, printers, wireless access points, and surveillance cameras. Each port features auto-negotiation for speed and duplex mode, along with Auto-MDI/MDIX crossover detection, eliminating the need for special crossover cables during installation.

2 x SFP (1000BASE-X) Uplink Ports

The two built-in SFP slots provide flexible, high-speed uplink connectivity. Administrators can populate these slots with industry-standard SFP transceivers (sold separately) to support Gigabit Ethernet over fiber optic (multimode or single-mode) or copper cabling. This flexibility is critical for long-distance backbone connections, connecting to a core switch or router, or linking to another building where fiber is required. The uplinks can also be configured for link aggregation (EtherChannel) to provide up to 2 Gbps of resilient, load-balanced uplink bandwidth.

Advanced Software Features and Network Intelligence

Beyond hardware, the switch runs Cisco's fully-featured IOS software, bringing enterprise-class intelligence to the network edge. The "-E" in the model name signifies the "IP Base" feature set image, which includes a comprehensive suite of Layer 2 and Layer 3 functionalities.

Layer 2 Switching and VLAN Support

The switch delivers comprehensive Layer 2 features, including IEEE 802.1Q VLAN trunking for segmenting network traffic, IEEE 802.1s Multiple Spanning Tree (MST) and 802.1w Rapid Spanning Tree Protocol (RSTP) for creating loop-free topologies with fast convergence, and EtherChannel (802.3ad LACP) for bundling multiple physical links into a single logical channel for increased bandwidth and redundancy.

Quality of Service (QoS) for Traffic Prioritization

To support converged networks carrying voice, video, and data, the Catalyst 3750V2 employs sophisticated QoS mechanisms. It can classify, police, prioritize, and mark traffic based on Layer 2 (CoS), Layer 3 (DSCP), or Layer 4 (TCP/UDP ports) information. This ensures that delay-sensitive applications like VoIP and video conferencing receive the necessary bandwidth and low latency, even during periods of network congestion.

Layer 3 Routing Capabilities

The IP Base software provides essential static and dynamic routing protocols. It supports Routing Information Protocol (RIPv1 and v2), Open Shortest Path First (OSPF) for more complex network topologies, and Enhanced Interior Gateway Routing Protocol (EIGRP) for efficient, rapid-converging routing within Cisco environments. This capability allows the switch to perform inter-VLAN routing, eliminating the need for an external router for communication between VLANs and improving overall network performance.

Security and Access Control

Network security is multi-layered. Features include IEEE 802.1x port-based authentication for user and device identity validation, Access Control Lists (ACLs) for granular traffic filtering, DHCP snooping to prevent rogue DHCP server attacks, IP Source Guard to block IP address spoofing, and Dynamic ARP Inspection (DAI) to mitigate ARP poisoning attacks. These features work in concert to create a secure access layer.

Deployment Scenarios and Use Cases

The versatility of the Catalyst 3750V2-24TS-E makes it suitable for a multitude of networking environments.

Enterprise Branch Office and Wiring Closet

In a branch office, it serves as the primary access switch, providing connectivity for employees, IP telephony, and local servers. Its Layer 3 routing capability allows it to handle local inter-VLAN traffic efficiently, while the SFP uplinks connect back to the corporate data center via a WAN router or directly over a metro Ethernet fiber link.

Converged Network for Voice, Video, and Data

The integrated QoS and high throughput make it an excellent choice for networks deploying Cisco Unified Communications solutions. It can prioritize voice traffic (tagged with a specific CoS/DSCP value) from IP phones, ensuring call quality, while simultaneously handling standard data traffic and video streams from surveillance systems or conferencing equipment.

Medium Business Core or Aggregation Switch

For a small to medium-sized business, a stack of Catalyst 3750V2 switches can function as the network core, aggregating traffic from multiple access switches and providing routing between departments (VLANs). The stacking redundancy and Layer 3 features offer a resilient and capable infrastructure without the cost of a modular chassis switch.

Reliability and Sustainability

Cisco designs its Catalyst series for continuous operation, and the 3750V2 model incorporates several features to uphold this promise.

Hardware Resilience and Power Efficiency

The V2 series introduced improved power supplies and components for greater energy efficiency, potentially qualifying for Cisco's EnergyWise program for power management. While it does not support internal redundant power supplies (RPS), its stackable nature provides a level of system redundancy. For critical applications, an external RPS can be used to protect against a single switch's power supply failure.

Comprehensive Management Options

The switch can be managed through multiple avenues: a familiar Cisco IOS Command-Line Interface (CLI) accessed via console, Telnet, or SSH; a web-based graphical interface (Cisco Device Manager) for simpler configuration; and integration with Cisco network management platforms like Cisco Prime Infrastructure for centralized control of large deployments. SNMP v1, v2c, and v3 are fully supported for monitoring.

Longevity and Investment Protection

As a member of the Catalyst family, this switch benefits from Cisco's long-term software maintenance and hardware support lifecycle. Its modular uplink design via SFPs protects the investment by allowing the network media to be changed without replacing the entire switch. The stacking capability provides a graceful growth path, enabling network expansion one switch at a time while maintaining a single management domain.
