Cisco Catalyst 3750 V2 24-Port PoE Switch

The Cisco Catalyst 3750 v2 Series is a line of energy-efficient, Layer 3, Fast Ethernet stackable switches designed for enterprise access layers. These switches support Cisco EnergyWise technology, enabling the monitoring and management of power consumption for reduced energy costs and environmental impact. They are backward compatible with Cisco Catalyst 3750 and 3750-E Series switches, allowing for network evolution and investment protection. The series offers various configurations, including models with Power over Ethernet (PoE) capabilities, suitable for powering devices such as IP phones and wireless access points.

### Technical Specifications

**Stacking Capabilities:**
* **Cisco StackWise Technology:** Creates a 32-Gbps switch interconnection, allowing up to nine switches to be stacked as a single logical unit.
* **Unified Management:** Stacks are managed as a single unit with a single IP address, simplifying management tasks such as fault detection, VLAN creation, network security, and QoS controls.
* **Backward Compatibility:** Stacks can include a mix of Cisco Catalyst 3750 v2, 3750, and 3750-E Series switches.
* **Hot-Swapping:** Switches can be added or removed from a stack without interrupting network service.
* **Maximum Ports per Stack:** Up to 468 Ethernet or PoE 10/100 ports when stacking nine switches.

**Layer 3 Features and Routing:**
* **Hardware-Based IP Routing:** Delivers high-performance IP routing using the Cisco Express Forwarding (CEF/dCEF) architecture.
* **Routing Protocols:** Supports a comprehensive range, including OSPF, IGRP, BGP-4, RIP-1, RIP-2, EIGRP, DVMRP, PIM-SM, static IP routing, and PIM-DM.
